Lenovo Top Choice

Lenovo offers two “quick-ship” programs to make it easy for our customers to get quick delivery of our offerings:

Lenovo Top Choice Express: A Configure-to-Order (CTO) model that uses a "best of" subset of components. It allows for customization while maintaining significantly faster lead times than standard CTO.

Top Choice Express (TCE) is the way to get custom configurations as quickly as possible. It allows DCSC configurator users to configure systems in CTO Mode, selecting the required hardware components while still benefiting from faster turnaround than traditional CTO. These configurations are built and fully integrated by Lenovo Manufacturing, with simple configuration steps, instant pricing, and quicker delivery.

To see which components are TCE, check the TCE column in the various component tables in this product guide. Green cells mean that the component is enabled for ordering with Top Choice Express in all regions world-wide. Orange cells with the symbol mean that the component is enabled for Top Choice Express in only some regions. Mouse over or tap on the cell to see which regions have it enabled for TCE.

Note: Top Choice Express is for configure-to-order builds only, not for standalone option part numbers.

Lenovo Top Choice Stock: Pre-built, fixed-configuration units held in distribution. They are the "Ready-to-Ship" inventory options for customers who need a server quickly.

Top Choice Stock (TCS) is used in Preconfigured Mode in DCSC, starting from a standard pre‑built configuration and adding option components as needed. Systems are assembled and fulfilled by Lenovo partners, enabling quick order processing and fast shipment through distribution. This path supports rapid delivery while maintaining flexibility through add‑on options. For details of TCS models, see the Preconfigured Models section.

Note: Ship dates are estimates only; actual ship times may vary based on platform and component availability, order processing, logistics, and external factors beyond Lenovo’s control. Lenovo is not liable for delays.

ThinkSystem SR650 V4 models can be configured by using the Lenovo Data Center Solution Configurator (DCSC).

Configure-to-order (CTO) models are used to create models with factory-integrated server customizations. For CTO models, two types of base CTO models are available for the SR650 V4 as listed in the columns in the following table:

General purpose base CTO models are for general business (non-HPC) and is selectable by choosing General Purpose mode in DCSC.
AI and HPC base models are intended for Artificial Intelligence (AI) and High Performance Computing (HPC) configurations and solutions are enabled using the AI & HPC Hardware - ThinkSystem Hardware mode in DCSC. These configurations, along with Lenovo EveryScale Solutions, can also be built using System x and Cluster Solutions Configurator (x-config). Tip: Some HPC and AI models are not listed in DCSC and can only be configured in x-config.

Preconfigured server models may also be available for the SR650 V4, however these are region-specific; that is, each region may define their own server models, and not all server models are available in every region.

The following table lists the base CTO models of the ThinkSystem SR650 V4 server.

The SR650 V4 uses an additional machine type of 7DK2 for water-cooled servers using the Compute Complex Neptune Core Module, where memory is water-cooled in addition to the two CPUs, as listed in the following table.

Servers of machine type 7DK2 share components with machine types 7DGD, however the system board is different. Specifically, there are fewer DIMM slots and the DIMM slots are spaced wider apart to accommodate the heat-transfer components.

Processor features

Processors supported by the SR650 V4 include embedded accelerators to add even more processing capability:

QuickAssist Technology (Intel QAT)

Help reduce system resource consumption by providing accelerated cryptography, key protection, and data compression with Intel QuickAssist Technology (Intel QAT). By offloading encryption and decryption, this built-in accelerator helps free up processor cores and helps systems serve a larger number of clients.

Intel Dynamic Load Balancer (Intel DLB)

Improve the system performance related to handling network data on multi-core Intel Xeon Scalable processors. Intel Dynamic Load Balancer (Intel DLB) enables the efficient distribution of network processing across multiple CPU cores/threads and dynamically distributes network data across multiple CPU cores for processing as the system load varies. Intel DLB also restores the order of networking data packets processed simultaneously on CPU cores.

Intel Data Streaming Accelerator (Intel DSA)

Drive high performance for storage, networking, and data-intensive workloads by improving streaming data movement and transformation operations. Intel Data Streaming Accelerator (Intel DSA) is designed to offload the most common data movement tasks that cause overhead in data center-scale deployments. Intel DSA helps speed up data movement across the CPU, memory, and caches, as well as all attached memory, storage, and network devices.

Intel In-Memory Analytics Accelerator (Intel IAA)

Run database and analytics workloads faster, with potentially greater power efficiency. Intel In-Memory Analytics Accelerator (Intel IAA) increases query throughput and decreases the memory footprint for in-memory database and big data analytics workloads. Intel IAA is ideal for in-memory databases, open source databases and data stores like RocksDB, Redis, Cassandra, and MySQL.

Intel Advanced Matrix Extensions (Intel AMX)

Intel Advanced Matrix Extensions (Intel AMX) is a built-in accelerator in Xeon 6 P-core processors that significantly improves deep learning training and inference. With Intel AMX, you can fine-tune deep learning models or train small to medium models in just minutes. Intel AMX offers discrete accelerator performance without added hardware and complexity.

The processors also support a separate and encrypted memory space, known as the SGX Enclave, for use by Intel Software Guard Extensions (SGX). The size of the SGX Enclave supported varies by processor model. Intel SGX offers hardware-based memory encryption that isolates specific application code and data in memory. It allows user-level code to allocate private regions of memory (enclaves) which are designed to be protected from processes running at higher privilege levels.

‡ These processors not have UPI links and are rich one-socket (R1S) processors

One-processor configurations

The SR650 V4 can be used with one processor installed. Most core functions of the server (including the XClarity Controller) are connected to processor 1 as shown in the System architecture section.

With only one processor, the server has the following capabilities:

16 memory DIMMs
Riser 1 (slots 1 & 2) and Riser 2 (slots 3, 4, 5)
OCP slot 1
Up to 16x 2.5-inch NVMe drives using onboard NVMe connections (24x NVMe supported using Tri-Mode)
Up to 16x E3.S 1T NVMe drives
Up to 6x CXL memory modules in E3.S 2T drive bays
Internal RAID adapter or HBA (CFF form factor)
M.2 drives
Processor cooling

The SR650 V4 offers four implementations to remove heat from the processors:

Entry heatsinks, suitable for configurations that generate lower heat levels, and processors ≤ 205W
Standard heatsinks with integrated heat pipes, suitable for configurations that generate lower heat levels, and processors ≤ 330W
Performance heatsinks with separate radiator connected heat pipes, suitable for most configurations
Open-loop liquid cooling of the processors, as described in the Lenovo Processor Neptune Core Module section
Open-loop liquid cooling of the processors and memory, as described in the Lenovo Compute Complex Neptune Core Module section

The SR650 V4 also supports advanced direct-water cooling (DWC) capability with the Lenovo Processor Neptune Core Module. This module implements a liquid cooling solution where heat from the processors is removed from the rack and the data center using an open loop and coolant distribution units.

With the Processor Neptune Core Module, all heat generated by the processors is removed from the server using water. This means that the server fans and data center air conditioning units only need to remove the heat generated by the other components. This results in lower air conditioning costs and it enables the use of slower fans which results in lower overall power consumption.

Internal testing has shows a 63% fan power saving per node and 24.7% rack-level power saving with the use of open-loop liquid cooling. Power savings are configuration dependent.

The following figure shows the Lenovo Processor Neptune Core Module.


Figure 9. Lenovo Processor Neptune Core Module

The Processor Neptune Core Module also includes a leak detection module which can detect a leakage of more than 0.5ml (about 10 drops) along the length of the tube and then issue an event to the XClarity Controller. XCC will then post an error to the System Event Log and enable further actions. Once the liquid evaporates, a further event is issue to XCC.

Lenovo Compute Complex Neptune Core Module - Open-loop liquid cooling

The SR650 V4 also supports advanced direct-water cooling (DWC) of the processors, memory DIMMs, and voltage regulators (collectively called the compute complex) with the Lenovo Compute Complex Neptune Core Module. This heat is removed from the rack and the data center using an open loop and coolant distrubution units.

With this solution, all heat generated by the compute complex is removed from the server using water, which means that the server fans and data center air conditioning units only need to remove the heat generated by the other components. This results in lower air conditioning costs and it enables the use of slower fans which results in lower overall power consumption.

Internal testing has shows an 92% fan power saving per node and 35.9% rack-level power saving with the use of open-loop liquid cooling. Power savings are configuration dependent. A rack cabinet with 20x SR650 V4 servers using 100% air cooling (PUE 1.6) requires 44.8 kW of data center power, including data center cooling costs, whereas 20x servers with Compute Complex Neptune Core Module with 80% liquid cooling (PUE 1.05) and 20% air cooling (PUE 1.6) requires 28.7 kW of data center power. This represents a 35.9% power saving at the rack level.

The following figure shows the Lenovo Compute Complex Neptune Core Module. The water flows past all DIMMs in parallel and then passes across both processors.

The Compute Complex Neptune Core Module also includes a leak detection module which can detect a leakage of more than 0.5ml (about 10 drops) along the length of the tube and then issue an event to the XClarity Controller. XCC will then post an error to the System Event Log and enable further actions. Once the liquid evaporates, a further event is issue to XCC.

UEFI operating modes

The SR650 V4 offers preset operating modes that affect energy consumption and performance. These modes are a collection of predefined low-level UEFI settings that simplify the task of tuning the server to suit your business and workload requirements.

The following table lists the feature codes that allow you to specify the mode you wish to preset in the factory for CTO orders.

Limited choice for LCC processors: If you select a processor with an LCC topology (see the Die column in the Processor features table), you will only be able to select General Computing - Power Efficiency (C3JB) in DCSC. The other modes are still supported, however, they can only be set in the field, not in the factory. Note that this is the only mode that is ERP Lot9-compliant for EU and UK customers.

The preset modes for the SR650 V4 are as follows:

ThinkSystem General Computing - Power Efficiency (feature C3JB): This workload profile optimizes the performance per watt efficiency with a bias towards performance. This workload profile is analogous to “Efficiency – Favor Performance” operating mode on ThinkSystem V3 servers. This profile contains settings for ENERGY STAR® and ERP Lot9 compliance.
ThinkSystem General Computing - Peak Frequency (feature C3JA): This workload profile is defined by the requirement to drive the highest core frequencies out of a processor across a subset of cores available – not for all cores active. This workload profile benefits workloads requiring either high per core and / or overall CPU package frequency. These workloads may have variable resource demands, are relatively insensitive to overall platform latency, and are generally CPU clock constrained. Tuning a system for highest possible core frequency may mean allowing inactive cores to transfer in and out of sleep states (C-states), which allows active cores to run at higher frequency for different durations of time. Allowing cores to go into low power states allows for higher per core frequency but can introduce “jitter” in the systems clock frequency.
ThinkSystem General Computing - Max Performance (feature C3J9): This workload profile maximizes the absolute performance of the system without regard for power savings. Power savings features are disabled. This operating mode should be used when an application can sustain work across all cores simultaneously and is Non-uniform Memory Access (NUMA) aware.
ThinkSystem High Performance Computing (HPC) (feature C3J8): This profile is for customers running large-scale scientific and engineering workloads. These environments tend to be clustered environments where each node performs at maximum utilization for extended periods of time, and the application is Non-Uniform Memory Access (NUMA) aware.
ThinkSystem Low Latency (feature C9U8): This workload profile seeks to minimize overall transaction latency. Low wait times for core-to-core, core-to-cache, CPU-to-memory, and CPU-to-adapter communication are critical. Clock frequency is only important in so far as it minimizes intra- and inter-CPU latency. This profile is characterized by maintaining low processor clock variability and maintaining all external CPU links, memory and PCIe subsystems at maximum frequency.
ThinkSystem Virtualization - Power Efficiency (feature C9UA): This workload profile is for virtualization environments. The profile ensures that all available virtualization options are enabled. Power saving features are enabled.
ThinkSystem Virtualization - Max Performance (feature C9U9): This workload profile is for virtualization environments. The profile ensures that  all available virtualization options are enabled. Power saving features are disabled.

CXL memory

The following table lists the CXL memory that are currently supported by the SR650 V4. These memory options are installed in the front E3.S 2T drive bays at the front of the server.

OS support for CXL: CXL memory is not supported with Windows Server and VMware ESXi. See OSIG for specifics:

* Quantities supported depends on DIMMs installed and the CXL interleaving setting. See the Memory module installation rules page in the User Guide

For servers that have a combination of DDR5 memory and CXL memory, you can specify how you want to the memory spaces to be presented to the operating system. For CTO orders, you can specify the factory to set the memory mode, as described in the table below. The memory mode can also be changed in UEFI at a later stage.

Table 22. Interleaving choices for CTO orders (Memory tab in DCSC)
Part number Feature
code Description Top Choice
Express Purpose
CTO only C8VB* DDR5 and (volatile) CXL Memory interleaved together in one 12-way set TCE Hetero or Heterogeneous mode. This mode supports memory interleave between CXL memory and DDR memory. Interleaving of memory requests across a combination of native attach DDR5 channels and CXL-connected memory to increase aggregate bandwidth. The entire combined capacity of DDR memory and CXL memory is visible to the software as a single NUMA domain. As a result, no software changes are needed in the system to use heterogeneous interleave mode.
CTO only C8VC Native DDR5(1LM) and CXL Memory(volatile) visible to SW as separate tiers, separately interleaved TCE 1LM+Vol mode. This is a 2-tier memory mode, where the DDR5 memory and CXL memory are different address spaces and separate NUMA nodes. This mode is also referred to as Software Managed tiering because the application must manage the placement of data in separate tiers and must manage any desired movement of data between tiers. This management of placement and movement may be performed by the OS, or by a higher-level middleware or directly by an application.

* Not supported with LCC processors. See the Processor features section to see which processors have an LCC die.

For more information on this memory, see the following Lenovo Press paper,

Introduction to CXL 2.0 Memory
Memory rules

The following rules apply when specifying the memory configuration:

The tables above list the supported quantities per processor. For two processors, install the same number of DIMMs to each processor. Other quantities are not supported.
Only a subset of processors support MRDIMMs - see the table in the Processor features section for specifics.
All installed RDIMMs must be identical part numbers; mixing not supported

CXL-related rules:

See the SR650 V4 User Guide for the supported combinations of CXL memory and RDIMM memory:
https://pubs.lenovo.com/sr650-v4/memory_module_installation_order_cxl
CXL heterogenous mode (feature C8VB) is not supported with processors with an LCC die. See the Processor features section to see which processors have an LCC die.
In the DCSC configurator, you must first select a CXL memory mode (Memory tab) before CXL memory modules can be selected (Storage tab)
CXL memory is installed in E3.S 2T drive bays, however hot-swap functionality is not supported

For best performance, consider the following:

Ensure the memory installed is at least the same speed as the memory bus of the selected processor.
Populate all memory channels.

The following memory protection technologies are supported:

ECC detection/correction
Bounded Fault detection/correction
SDDC (for 10x4-based memory DIMMs; look for "x4" in the DIMM description)
ADDDC (for 10x4-based memory DIMMs)
Memory mirroring

See the Lenovo Press article "RAS Features of the Lenovo ThinkSystem Intel Servers" for more information about memory RAS features: https://lenovopress.lenovo.com/lp1711-ras-features-of-the-lenovo-thinksystem-intel-servers

If memory channel mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per processor), and both DIMMs in the pair must be identical in type and size. 50% of the installed capacity is available to the operating system.

Memory rank sparing is implemented using ADDDC/ADC-SR/ADDDC-MR to provide DRAM-level sparing feature support.

Memory DIMM filler

When a GPU (or another high-thermal component) is added as a field upgrade, all empty DIMM slots must have a DIMM filler (also called a dummy DIMM or DIMM blank) installed in each DIMM slot, to ensure the optimal air flow. Ordering information is in the following table. For CTO orders, the DIMM fillers are derived by the configurator.

Internal storage

The SR650 V4 has three drive bay zones and supports up to 16x 3.5-inch or 40x 2.5-inch hot-swap drive bays or a combination of drive bays, depending on the selected chassis and backplane configuration. The server also supports configurations with E3.S 1T and E3.S 2T drive bays including support for CXL memory in the E3.S 2T form factor. The server supports configurations without any drive bays if desired.

The three drive bay zones are as follows:

Front:
Up to 12x 3.5-inch hot-swap bays, or
Up to 24x 2.5-inch hot-swap bays, or
Up to 32x E3.S 1T or 12x E3.S 2T hot-swap drive bays (or a mix of 1T/2T drive bays)
Middle:
8x 2.5-inch simple-swap bays
Rear:
4x 3.5-inch hot-swap bays, or
Up to 8x 2.5-inch hot-swap bays

The server also supports one or two M.2 drives, in three possible locations, configuration dependent:

Installed in an M.2 adapter internal to the server (non-hot-swap)
Hot-swap in the rear of the server
Hot-swap in the front of the server

The SR650 V4 supports NVMe drives to maximize storage performance.

In a 2.5-inch drive configuration, the server supports up to 36 NVMe drives without oversubscription (that is, each x4 drive has a dedicated x4 (4 lanes) connection to the processor)
Up to 24 installed in front bays
Up to 28 installed in the front and rear bays
Up to 32 installed in front and mid bays
Up to 36 installed in front, mid and rear bays
In a 3.5-inch drive configuration, the server supports up to 4x 3.5-inch NVMe or 8x 2.5-inch NVMe drives without oversubscription
In a E3.S front drive configuration, the server supports up to 32x NVMe drives without oversubscription:
32x E3.S 1T NVMe drives at the front
12x E3.S 2T NVMe drives at the front
Combinations of E3.S 1T and 2T drive bays

In addition, the SR650 V4 supports two M.2 NVMe drives for use as boot drives, as described in the M.2 drives section

The specifics of these configurations are covered in the Storage configurations section. The tables in those sections indicate the number of NVMe drives in each configuration. The storage configuration tables also include a column that indicates the number of PCIe slots that are available.

The number of NVMe drives affects the number of PCIe slots that are available, as listed in the following tables. This is because the onboard PCIe MCIO connectors are used for both slots and NVMe drives.

Tri-Mode support - RAID 940 adapters

The RAID 940 adapters support NVMe through a feature named Tri-Mode support (or Trimode support). This feature enables the use of NVMe U.3 drives at the same time as SAS and SATA drives. Tri-Mode requires an AnyBay backplane. Cabling of the controller to the backplanes is the same as with SAS/SATA drives, and the NVMe drives are connected via a PCIe x1 link to the controller.

NVMe drives connected using Tri-Mode support provide better performance than SAS or SATA drives: A SATA SSD has a data rate of 6Gbps, a SAS SSD has a data rate of 12Gbps, whereas an NVMe U.3 Gen 4 SSD with a PCIe x1 link will have a data rate of 16Gbps. NVMe drives typically also have lower latency and higher IOPS compared to SAS and SATA drives. Tri-Mode is supported with U.3 NVMe drives and requires an AnyBay backplane.

Tri-Mode requires U.3 drives: Only NVMe drives with a U.3 interface are supported. U.2 drives are not supported. See the Internal drive options section for the U.3 drives supported by the server.

New as of July 2026: To enable Tri-Mode in CTO orders of the SR650 V4, use the following feature code:

Table 27. Tri-Mode Enablement
Feature code Description Lenovo
Top Choice
Express
CH5Z Tri-Mode Enablement TCE

The process to configure Tri-Mode for a CTO order in DCSC is as follows:

In the Storage tab, select one of the 940-8i or 940-16i controllers from the SAS/SATA RAID Controller group
In the Internal Storage tab, select select Tri-Mode Enablement (feature CH5Z)
You can then select either NVMe or SATA or SATA drives or any combination of these drives, up to the number supported by the server and the backplanes selected.

Tips:

Feature CH5Z is not selectable until one of the 940-8i or 940-16i adapters in SAS/SATA RAID Controller group is selected.
Feature CH5Z is not selectable if Non RAID NVMe (BC4V) is selected.
The existing Tri-Mode "for U.3" adapter feature codes (features BGM1, BGM0, BM36, BDY4) in the Tri-Mode Controller group are for existing orders only and are being phased out (deprecated)

Front drive bays

The front drive bay zone supports the following configurations:

8x or 12x 3.5-inch drive bays (hot-swap)
8x, 16x or 24x 2.5-inch drive bays (hot-swap)
Up to 32x E3.S 1T drive bays (hot-swap)
Up to 12x E3.S 2T drive bays for CXL memory (non-hot-swap)
No backplanes and no drives (supports field upgrades)

The specific combinations that are supported in the SR650 V4 are shown in the following figures. The feature codes listed are the backplane feature codes when ordering CTO and correspond to the feature codes listed in the table below the figure.

The following figure shows the supported 3.5-inch drive bay configurations.

Tip: The 8x 3.5-inch backplane (C4DB) is for GPU configurations only.

GPU configurations with 3.5-inch drives: The 8x 3.5-inch backplane (C4DB) is for use with GPUs only (see configurations 117-1 and 117-2 in the Storage configurations section). The use of a GPU with 3.5-inch front drive bays requires this backplane. In DCSC, the selection of this backplane requires a GPU.

Field upgrades: All front backplanes are available as part numbers for field upgrades along with require cable option kits, as described in the Field upgrades section below.

The use of front drive bays has the following configuration rules:

The SR650 V4 also supports configurations without any drive bays, allowing for drive bay upgrades as described in the field upgrades section.
If 3.5-inch front drive bays are used, an internal (CFF) RAID adapter or HBA is not supported as the adapter and bays occupy the same physical space
Backplane C4DB (ThinkSystem 2U V4 12x3.5" SAS/SATA Backplane (For GPU Configurations Only, 8 Drives Max)) only supports 8x drives even though it is a 12-bay backplane. This is so that the backplane can be configured with GPUs which require additional airflow. Since this is a 12-bay backplane, a 16i adapter is required for the proper cabling of the 8x active drive bays. An 8i adapter may be supported through special bid - see your sales representative for details.
Any of the following front drive configurations can be configured with front-mounted hot-swap M.2 drives, as described in the M.2 drives section:
Any 8x 2.5-inch and 16x 2.5-inch drive configuration (SAS/SATA, AnyBay, or NVMe)
Any E3.S configuration with 6 or fewer backplanes
Mid drive bays

The SR650 V4 supports simple-swap drives installed in the middle of the server chassis. The drive bays are accessible by removing the top lid of the server and levering the mid drive chassis up at the front.

The following configurations are supported:

8x 2.5-inch simple-swap SAS/SATA drive bays
8x 2.5-inch simple-swap NVMe drive bays

The drive bays in the open position are shown in the following figure.

Simple-swap drive bays: The drives that are installed in the mid-chassis drive bays are simple-swap, not hot-swap, even though the drives use hot-swap drive trays.

M.2 support: When mid drive bays are configured, the M.2 adapter is installed on the mid drive bay mechanical as shown in the images.

‡ 2.5-inch drive backplanes for the mid-chassis area must be installed in pairs. NVMe and SAS/SATA cannot be mixed.

Field upgrades: Backplanes are available as part numbers for field upgrades along with require cable option kits, as described in the Field upgrades section below.

The use of drive bays in the mid-chassis area has the following configuration rules:

All processors are supported. Higher TDP processors will require the performance heatsinks.
Full-length adapter cards are not supported
GPUs (including low profile GPUs such as the NVIDIA L4) are not supported
The mid drive bays and slots 2 & 10 share the same power connectors, so mid drive bays are mutually exclusive with slots 2 and 10. The only exception to this is config 27 with 8x mid drives and 8x rear drives - this configuration also supports slots 1 & 2.
Rear drive bays

The SR650 V4 supports hot-swap drives installed at the rear of the server chassis. Supported configurations are as follows:

3.5-inch hot-swap drives
4x SAS/SATA drive bays
2.5-inch hot-swap drives
4x SAS/SATA drive bays
4x NVMe Gen5 drive bays

Field upgrades

The SR650 V4 is orderable without drive bays, allowing you to add a backplane, cabling and controllers as field upgrades. The server also supports upgrading some configurations by adding additional front drive bays (for example, upgrading from 8 to 16x 2.5-inch drive bays).

Upgrade path: The key criteria for upgrade support is to ensure that the target configuration is one of the supported drive bay configurations as listed in the Supported drive bay combinations section.

To add drive bays you will need to order both drive backplanes and cable kits. Backplane kits do not include cables.

In this section:

Drive bay field upgrades - 3.5-inch chassis
Drive bay field upgrades - 2.5-inch chassis
Drive bay field upgrades - E3.S chassis
Drive bay field upgrades - Compute Complex Neptune water cooling
Adding an Internal (CFF) RAID adapter or HBA
Adding an Internal SAS Expander
Adding a RAID 960W-32i adapter
Replacement cable routing walls
RAID flash power module (supercap) support
2.5-inch drive bay fillers

When adding drive bays, you will also need to add the appropriate storage controller(s). Consult the tables in the Storage configurations section to determine what controller sections are supported and what additional controllers you will need. Controllers are described in the Controllers for internal storage section.

Drive bay field upgrades - 3.5-inch chassis

The table below lists the backplane kits and cable kits needed to build one of the supported 3.5-inch chassis configurations.

The Config numbers listed here match the configuration listed in the Storage configuration Overview and Details sections.

Return to Field upgrades.

Replacement cable routing walls

Cable walls are used to guide signal and power cables through the server and to maximize airflow across the components. The server comes with 1U cable walls at both side of the processor board. It is recommended to replace the 1U cable walls with 2U cable walls when there are more than five cables routed at one side.

The 2U cable walls are required for some E3.S configurations and will be automatically derived for CTO orders. For field upgrades, see the Drive bay field upgrades - E3.S chassis section, where the table indicates when replacement cable walls are required.

RAID flash power module (supercap) support

High-end RAID adapters such as the RAID 940 Series include a RAID flash power module (supercap) that needs to be mounted properly. Supercap holders are integrated into the air baffles and mid-chassis drive cage. No additional components are needed.

There are up to four possible locations for supercaps, depending on the air baffle or mid-chassis drive bays installed, as follows:

Standard air baffle: 4 supercaps
GPU air baffle: 4 supercaps
2.5-inch mid-chassis drive bays: 2 supercaps

Note: Configurations with mid-chassis drive bays only support two supercaps. As a result, such server configurations only support two RAID adapters if the adapters include supercaps.

See the following User Guide page for the specifics on the locations:
https://pubs.lenovo.com/sr650-v4/supercap_replacement

2.5-inch drive bay fillers

Backplane option kits include the necessary drive bay fillers, however if needed, additional blanks can be ordered as listed in the following table.

M.2 drives

The SR650 V4 supports one or two M.2 form-factor SATA or NVMe drives for use as an operating system boot solution or as additional storage.

M.2 drives can be installed in one of the following locations:

Internal to the server (non-hot-swap) on an M.2 module which is mounted horizontally in the server. RAID is either integrated or with the use of VROC, depending on the M.2 adapter selected.

Locations of the internal M.2 are as follows:

In servers without mid-chassis drives, the M.2 module is mounted on the air baffle
With a mid-chassis drive cage, the M.2 module is mounted on the drive cage, as shown in the Mid drive bays section.
Rear-mounted hot-swap M.2 drives with integrated RAID. Supported in slot 8 or slot 5.
Front-mounted hot-swap M.2 drives with integrated RAID. Only supported with E3.S and 2.5-inch front drive configurations.

In this section:

M.2 adapter features
M.2 field upgrades for internal M.2
M.2 field upgrades for hot-swap M.2

Hot-swap tips:

The bare M.2 drives (as listed in the Internal drive options section) are non-hot-swap drives. However, when they are installed in the assembly for front-mounted or rear-mounted M.2, the drives are hot-swap enabled.
When a hot-swap M.2 adapter is ordered in the DCSC configurator, non-hot-swap drives are displayed for selection. The configurator automatically includes the hot-swap assembly to covert the non-hot-swap drives to hot-swap.

The following figure shows the SR650 V4 with front and rear hot-swap M.2 drive bays.

Encryption Enablement

For CTO orders, the configurator allows you to specify that you want to create an "encryption-ready" server, and to ensure that only components that support encryption are selectable in the configurator. This is done in DCSC and x-config configurator tools by selecting the feature code listed in the following table.

Table 53. Encryption Enablement
Part number Feature code Description Top Choice
Express
CTO only CES1* Drive Encryption Enablement (not supported with vSAN) TCE

* In DCSC, this feature is in Storage > Internal Storage under the heading "Encryption Enablement"

Tip: This feature will not be selectable until an SED-capable drive is selected.

By selecting this feature code, the following requirements will be enabled in the configurator:

SED drives will be required
XCC3 Premier will be required
VROC NVMe RAID cannot be selected
440-8i and 440-16i HBAs cannot be selected

Configuration notes:

Do not use this feature code for VMware vSAN or Nutanix servers, since these virtualization offerings do not support HW RAID adapter-based encryption
Selecting this feature code does not enable encryption at the factory
If you don't select this feature code, you will still be able to enable encryption in your server, however you will need to ensure that you have suitable storage controllers and drives installed in the server

Controllers for internal storage

The SR650 V4 offers a variety of controller options for internal drives:

For 2.5-inch and 3.5-inch drives:
RAID adapters and HBAs for SAS/SATA drives (PCIe slot-based)
RAID adapters and HBAs for SAS/SATA drives (cabled in a dedicated space)
Onboard NVMe ports with RAID support using Intel VROC NVMe RAID
Tri-Mode support using RAID 940 adapters for NVMe drives, with RAID provided by the RAID adapter
RAID 960W-32i adapter for NVMe x2 support (max 16 drives per adapter)
For E3.S EDSFF drives:
Onboard NVMe ports with RAID support using Intel VROC NVMe RAID
For M.2 drives (see M.2 drives section)
SATA controller integrated on the M.2 adapters
NVMe controller integrated on the M.2 adapters (Intel VROC for RAID)

As well as supporting RAID adapters and HBAs that install in a PCIe slot, the SR650 V4 with 2.5-inch front drive bays supports a custom form factor (CFF) adapter that is mounted in the server and cabled to one of the onboard NVMe ports.

The following table lists the adapters used for the internal storage of the server. For VROC ordering information, see the Intel VROC section.

The table includes a Top Choice Express column; for CTO orders, select a TCE component for faster delivery. See the Top Choice section for more information.

No Onboard SATA support: The processors in the SR650 V4 do not offer onboard SATA support. For SATA drives, you will need either a RAID adapter or an HBA.

* CFF (custom form factor) is the name for the cabled internal adapter form factor that doesn't occupy a standard PCIe slot
† with Tri-Mode enabled, the adapter supports PCIe 4.0 x1 connectivity to NVMe drives with U.3 interface

Configuration notes:

Supercap support limits the number of RAID adapters installable: The table lists whether the adapter includes a power module (supercap) to power the flash memory. The server supports between 1 and 3 supercaps depending on the server configuration as described in the RAID flash power module (supercap) support section. The number of supercaps supported also determines the maximum number of RAID adapters with flash that can be installed in the server.
Field upgrades: If you are adding a RAID adapter with supercap to the server as a field upgrade, you may need a supercap holder as described in the RAID flash power module (supercap) support section.
Tri-Mode support and U.3 drives: The use of a RAID adapter with Tri-Mode enabled requires U.3 drives (U.2 drives are not supported). Also, in the DCSC configurator, 7500 PRO and 7500 MAX U.3 drives can only be selected when a Tri-Mode RAID adapter is also selected.

The onboard NVMe support has the following features:

Support integrated into the Intel processor
Each drive has PCIe 5.0 x4 host interface
Supports JBOD
Supports RAID using Intel VROC

Tri-Mode support - RAID 940 adapters

The RAID 940 adapters support NVMe through a feature named Tri-Mode support (or Trimode support). This feature enables the use of NVMe U.3 drives at the same time as SAS and SATA drives. Tri-Mode requires an AnyBay backplane. Cabling of the controller to the backplanes is the same as with SAS/SATA drives, and the NVMe drives are connected via a PCIe x1 link to the controller.

NVMe drives connected using Tri-Mode support provide better performance than SAS or SATA drives: A SATA SSD has a data rate of 6Gbps, a SAS SSD has a data rate of 12Gbps, whereas an NVMe U.3 Gen 4 SSD with a PCIe x1 link will have a data rate of 16Gbps. NVMe drives typically also have lower latency and higher IOPS compared to SAS and SATA drives. Tri-Mode is supported with U.3 NVMe drives and requires an AnyBay backplane.

Tri-Mode requires U.3 drives: Only NVMe drives with a U.3 interface are supported. U.2 drives are not supported. See the Internal drive options section for the U.3 drives supported by the server.

New as of July 2026: To enable Tri-Mode in CTO orders of the SR650 V4, use the following feature code:

Table 55. Tri-Mode Enablement
Feature code Description Lenovo
Top Choice
Express
CH5Z Tri-Mode Enablement TCE

The process to configure Tri-Mode for a CTO order in DCSC is as follows:

In the Storage tab, select one of the 940-8i or 940-16i controllers from the SAS/SATA RAID Controller group
In the Internal Storage tab, select select Tri-Mode Enablement (feature CH5Z)
You can then select either NVMe or SATA or SATA drives or any combination of these drives, up to the number supported by the server and the backplanes selected.

Tips:

Feature CH5Z is not selectable until one of the 940-8i or 940-16i adapters in SAS/SATA RAID Controller group is selected.
Feature CH5Z is not selectable if Non RAID NVMe (BC4V) is selected.
The existing Tri-Mode "for U.3" adapter feature codes (features BGM1, BGM0, BM36, BDY4) in the Tri-Mode Controller group are for existing orders only and are being phased out (deprecated)

Intel VROC onboard RAID

Intel VROC (Virtual RAID on CPU) is a feature of the Intel processor that enables Integrated RAID support.

On the SR650 V4, Intel VROC provides RAID functions for the onboard NVMe controller (Intel VROC NVMe RAID).

VROC NVMe RAID offers RAID support for any NVMe drives directly connected to the ports on the server's system board or via adapters such as NVMe retimers or NVMe switch adapters. On the SR650 V4, RAID levels implemented are based on the VROC feature selected as indicated in the following table. RAID 1 is limited to 2 drives per array, and RAID 10 is limited to 4 drives per array. Hot-spare functionality is also supported.

Performance tip: For best performance with VROC NVMe RAID, the drives in an array should all be connected to the same processor. Spanning processors is possible however performance will be unpredictable and should be evaluated based on your workload.

The SR650 V4 supports the VROC NVMe RAID offerings listed in the following table.

4L47A39164 B96G Intel VROC (VMD NVMe RAID) Premium TCE Yes Yes Yes Yes Yes Yes

Configuration notes:

If a feature code is ordered in a CTO build, the VROC functionality is enabled in the factory. For field upgrades, order a part number and it will be fulfilled as a Feature on Demand (FoD) license which can then be activated via the XCC management processor user interface.
SED functionality is not supported with VROC NVMe RAID

Virtualization support: Virtualization support for Intel VROC is as follows:

VROC (VMD) NVMe RAID: VROC (VMD) NVMe RAID is supported by ESXi, KVM, Xen, and Hyper-V. ESXi support is limited to RAID 1 only; other RAID levels are not supported. Windows and Linux OSes support VROC RAID NVMe, both for host boot functions and for guest OS function, and RAID-0, 1, 5, and 10 are supported. On ESXi, VROC is supported with both boot and data drives.
Internal drive options

VMware vSAN and Microsoft S2D configurations: Vendor Agnostic (VA) drives are based on drives from multiple vendors, and not all vendor variants are VMware vSAN or Microsoft S2D certified. Additionally, ISVs require a single drive vendor per host and cluster to ensure optimal performance; a requirement that VA drives may not consistently meet. To ensure certification compliance, hardware uniformity, and alignment with VMware and Microsoft best practices, use ThinkAgile VX or ThinkAgile FX for all vSAN configurations and ThinkAgile MX for all S2D configurations, instead of general purpose ThinkSystem servers.

The following tables list the drive options for internal storage of the server.

Internal backup units

The server does not supports any internal backup units, such as tape drives or RDX drives. External backup units are available as described in the External backup units section.

Optical drives

The server supports the external USB optical drive listed in the following table.

Part number Feature code Description Lenovo
Top Choice
Express
7XA7A05926 AVV8 ThinkSystem External USB DVD RW Optical Disk Drive TCE

The drive is based on the Lenovo Slim DVD Burner DB65 drive and supports the following formats: DVD-RAM, DVD-RW, DVD+RW, DVD+R, DVD-R, DVD-ROM, DVD-R DL, CD-RW, CD-R, CD-ROM.

I/O expansion

The SR650 V4 supports a total of up to 10x PCIe slots plus 2x OCP slots, all at the rear of the server. Slot availability is based on riser selection and drive bays configured.

Internal (CFF) RAID adapter/HBA: For configurations with 2.5-inch front drive bays, an internal RAID adapter or HBA (also known as CFF or custom form factor) can be installed in a dedicated space and cabled to a PCIe 4.0 x8 connector, thereby freeing up a slot for other purposes. E3.S configurations do not support a RAID adapter.

Topics in this section:

Slot ordering information
Slot configurations
Slot field upgrades
Serial port

The following figure shows the locations of the rear-accessible slots. The rear OCP slots are located below the PCIe slots. All slots are PCIe Gen 5.


Figure 24. SR650 V4 rear slots

The supported slot and riser card combinations are as follows:

Riser 1: Slots 1 & 2 (connects to CPU 1), low-profile slots (full height when configured with 8x 2.5-inch rear drive bays)
x8, x8
x8, x16 (only supported when configured with 8x 2.5-inch rear drive bays)
Riser 2: Slots 3, 4 & 5 (connects to CPU 1), full-height slots
x8, x16, x16 (most configurations)
Empty, x16, x16 (use with double-wide GPU in slot 4)
x16, x16, x16 (for configurations with 4x 2.5-inch rear drive bays)
Empty, Empty, x16 (use with 4x3.5-inch or 8x2.5-inch rear drive bays)
Other configurations available
Riser 3: Slots 6, 7 & 8 (connects to CPU 2), full-height slots
x8, x16, x16 (most configurations)
Empty, x16, x16 (use with double-wide GPU in slot 7)
Empty, Empty, x16 (use with any 2.5-inch or 3.5-inch rear drive bays)
Other configuraitons available
Riser 4: Slots 9 & 10 (connects to CPU 2), low-profile slots
x8, x8
x8, Empty

For details, see the Slot configurations section.

All x8 slots are open-ended slots, which means they can physically support x16 adapters even though only 8 lanes (x8) will be connected.

In addition, the server has two OCP slots:

OCP1 (connects to CPU 1)
Choice 1: x8
Choice 2: x16 (requires ThinkSystem SR650 V4/SR630 V4 x16 OCP Cable Kit, feature C1YK)
OCP2 (connects to CPU 2)
Choice 1: x8
Choice 2: x16 (requires ThinkSystem SR650 V4/SR630 V4 x16 OCP Cable Kit, feature C1YK)

Slots can be used in conjunction with rear 2.5-inch or 3.5-inch drive bays. Slot 8 can instead be configured as a pair of hot-swap M.2 drives. Combinations are shown in the following figure.

Riser 1 slots: With most configurations, slots 1 and 2 (Riser 1) are Low Profile slots, however with the 8x 2.5-inch drive configuration, the slots in Riser 1 are Full Height slots.

Slot ordering information

In the SR650 V4, slots are configured one slot at a time, based on customer need for PCIe slots. This is different to prior generations, where slots were configured at the complete riser level, not the slot level.

The DCSC configurator includes a new slot configuration wizard which will automate the selection of slots and riser cages, based on the adapters and rear drive bays selected. The wizard includes a visual representation of where each adapter is to be placed.

The SR650 V4 uses a modular riser card design for Riser 2 and Riser 3, in that risers start with only 1 slot (slot 5 or slot 8) and can be configured with additional slots as needed. Additional slots can be configured CTO and built in the factory, or can be added as field upgrades after delivery. Slots 5 and 8 are connected to riser slots on the system board. The other slots (slots 4 & 3 for Riser 2 and slots 7 & 6 for Riser 3) are connected via cables to additional PCIe connectors on the system board. This "pay-as-you-go" design ensures that your server configuration only includes the adapter slots you need, thereby minimizing the cost of the overall server solution.

Tip: For Riser 2 and Riser 3, you do not need to select the lower slots before selecting upper slots. For example, you can select slots for Slot 3 and Slot 4, but leave Slot 5 empty.

The two slots in Riser 1 and Riser 4 are installed as a pair. Both must be selected and installed at the same time.

The following table lists the ordering information for the rear slots. The table includes a Top Choice Express column; for CTO orders, select a TCE component for faster delivery. See the Top Choice section for more information.

GPU configuration rules

The following configuration requirements must be met when installing GPUs:

The table includes a Controlled GPU column. If a GPU is listed as Controlled, that means the GPU is not offered in certain markets, as determined by the US Government. If a GPU is listed as No, that means the GPU is not controlled and is available in all markets.
All GPUs installed must be identical
When a double-wide GPU is installed in slot 4 or 7, the adjacent slot 3 and 6 respectively is not available
Middle drive bays and Rear drive bays are not supported
For configurations with 3.5-inch front drive bays, the 8x 3.5-inch backplane (C4DB) is the only backplane supported (configurations 117-1 and 117-2 in the Storage configurations section); Backplanes supporting 12x 3.5-inch drive bays are not supported. In DCSC, the selection of this backplane requires a GPU.
GPUs are not supported with the ThinkSystem V4 1U/2U Compute Complex Neptune Core Module (machine type 7DK2)

For additional GPU requirements, see the Thermal rules page in the User Guide:

Configuration rules:

When 2x power supplies are installed, they form a redundant pair; power supplies must be identical part numbers
Most power supplies require that 2x PSUs be installed - See the Minimum Quantity column for specifics.

Supported voltage ranges are as follows:

The 230V/115V AC power supplies support both low-range (100-127V 50/60 Hz) and high-range (200-240V 50/60 Hz) power, except where noted. For China customers, all power supplies support 240V DC.
The -48V DC power supply supports voltage range -44V to -54V DC.
The HVAC/HVDC power supply supports voltage ranges 200-277V AC single phase, and 240-380V DC

For inlet current requirements, see the Physical and electrical specifications section.

Power supply options do not include a line cord. See the tables below for details about supported line cords, including the power cords for the DC power supplies. For server configurations, the inclusion of a power cord is model dependent. Configure-to-order models can be configured without power cords if desired.

The SR650 V4 supports both CRPS and CRPS Premium power supplies. CRPS Premium power supplies offer the following additional features:

Over-subscription
More accurate power metering
Virtual reseat
Enhanced fault detection
System cooling assist (fan override)
Fault LEDs
VPD support
Zero-output mode support (cold redundancy mode) (see the Zero-output mode section)

Power supply LEDs

CRPS Premium power supplies have two LEDs:

Power output/fault LED:
Green: The server is on and the power supply is working normally
Green, slow blinking (1 flash/sec): The power supply is in Zero-output/Standby mode (see below)
Green, fast blinking (5 flashes/sec): The power supply unit is in firmware update mode
Yellow: The power supply unit may have failed.
Off: The server is powered off, or the power supply is not working properly
Power input LED:
Green: The power supply is connected to the input power source
Off: The power supply is disconnected from the AC power source or a power problem has occurred

CRPS power supplies have one LED:

Green: The server is on and the power supply is working normally
Green, blinking: The power supply unit is in firmware update mode
Yellow: Either the power supply has failed, or two power supplies are installed but one is not connected to the input power source
Yellow, blinking: The power supply is indicating a warning such as over-temperature warning, over-current warning, or a slow fan speed
Off: The server is powered off, or the power supply is not working properly

Zero-output mode

Zero-output mode (also known as Standby mode or Cold Redundancy mode) allows a power supply to enter a low-power mode when it is not needed. Zero-output mode is only supported on CRPS Premium power supplies.

When Zero-output mode is configured in XCC and the server power load is sufficiently low, one of the installed power supplies enters into the Standby state while the other one delivers entire load. When the power load increases, the standby power supply will switch to Active state to provide sufficient power to the server.

Zero-output mode can be enabled or disabled in the XClarity Controller web interface, Server Configuration > Power Policy. If you select Disable, then both power supplies will be in the Active state.

Supported with CRPS Premium only: Zero-output mode is supported with CRPS Premium power supplies, but not with CRPS non-Premium power supplies

Power cords (C13 connectors)

Line cords and rack power cables with C13 connectors can be ordered as listed in the following table.

115V customers: If you plan to use the 1300W power supply with a low-range (100-127V) power source, select a power cable that is rated above 10A. Power cables that are rated at 10A or below are not supported with low-range power.

System I/O Board (DC-SCM)

The SR650 V4 implements a separate System I/O Board, also known as the DC-SCM (Data Center Secure Control Module, DCSCM), that connects to the system board as shown in the Internal view in the Components and connectors section. The System I/O Board contains connectors that are accessible from the exterior of the server as shown in the following figure.

Note: The NMI (non-maskable interrupt) button is no longer present on the board. Lenovo recommends using the NMI function that is part of the XCC user interfaces instead.


Figure 32. System I/O Board

The board also has the following components:

XClarity Controller 3, implemented using the ASPEED AST2600 baseboard management controller (BMC).
Root of Trust (RoT) module - implements Platform Firmware Resiliency (PFR) hardware Root of Trust (RoT) which enables the server to be NIST SP800-193 compliant. For more details about PFR, see the Security section.
MicroSD card port to enable the use of a MicroSD card for additional storage for use with the XCC3 controller. XCC3 can use the storage as a Remote Disc on Card (RDOC) device (up to 4GB of storage). It can also be used to store firmware updates (including N-1 firmware history) for ease of deployment.

Tip: Without a MicroSD card installed, the XCC controller will have 100MB of available RDOC storage.

Ordering information for the supported Micro SD cards are listed in the MicroSD for XCC local storage section.

Local management

The SR650 V4 offers a front operator panel with key LED status indicators, as shown in the following figure.

Tip: The Network LED only shows network activity of an installed OCP network adapter. The LED shows activity from both OCP adapters if two are installed.


Figure 33. Front operator controls are on the left and right side of the server

Front DisplayPort video port and Front/Internal USB ports

The rear USB ports and VGA video port are standard on all models of the SR650 V4, however the front and internal USB ports, and front MiniDP video port are optional, and can be configured in the factory in CTO orders, or as field upgrades using option part numbers.

Internal USB port: The internal USB port supports USB drives that have an overall length of less than 30mm. See the USB flash drive section for the supported drive.

For CTO orders, the feature codes are listed in the following table.

ThinkSystem 1U/2U V4 Front Media Bay Option kit (4X97A96850) is required to use XClarity Mobile, as described in the System status with XClarity Mobile section.
External Diagnostics Handset

The SR650 V4 optionally has a port to connect an External Diagnostics Handset as described in the preceding section. The External Diagnostics Handset has the same functions as the Integrated Diagnostics Panel but has the advantages of not consuming space on the front of the server plus it can be shared among many servers in your data center. The handset has a magnet on the back of it to allow you to easily mount it on a convenient place on any rack cabinet.


Figure 34. External Diagnostics Handset

The External Diagnostics Handset allows quick access to system status, firmware, network, and health information. The LCD display and the function buttons give you access to the following information:

Lenovo XClarity One

Lenovo XClarity One is a cloud-native unified Management-as-a-Service (MaaS) platform, engineered to modernize IT infrastructure. .

XClarity One is the next milestone in Lenovo’s portfolio of systems management products. Now you can leverage the benefits of a true next-generation platform for the deployment, management, and maintenance of your infrastructure through a single, centralized platform that delivers a consistent user experience across all Lenovo products.

XClarity One's primary architectural value is divided into three key areas:

How it predicts issues (AI/Analytics)
How it securely connects (Secure Management Hubs),
How it actually configures the hardware at scale (Template-Driven Lifecycle Control)

AI-powered Automation

XClarity One harnesses the power of AI and predictive analytics to enhance the performance and reliability of your infrastructure with proactive protection.

AI-Powered Predictive Failure Analytics - XC1 utilizes machine learning infrastructure to look at live device telemetries. The platform securely collects memory-diagnostic logs and pushes them into an active MPFA AI model infrastructure to analyze health patterns and predict probable hardware degradation before it manifests as a hard failure.
AI-Powered Call-Home - A Call-Home serviceable event opens a support ticket automatically, leveraging AI technology (in the case of MPFA) for problem determination and fast resolution automatically dispatching parts and services, reducing service costs and minimizing downtime.

Secure Management Hub

Lenovo’s proprietary Management Hub is an on-premises virtual appliance that acts as the bridge between your infrastructure and the cloud.

On-Premises Security with Cloud Flexibility - your infrastructure has no direct connection to the cloud, greatly reducing your attack surface from external threats while still having the deployment benefits, flexibility, and scalability of a cloud solution.
Authentication and Authorization - built on a Zero Trust Architecture and requiring OTP Application authentication for all users to handle the support of all customers’ servers and client devices. Role-based access controls help define and restrict permissions based on user roles.

Template-Driven Lifecycle Control

Lenovo’s unified management model eliminates fragmented server administration, allowing you to deploy, track, and maintain your entire infrastructure fleet from a single cloud-native dashboard.

Automated Configuration and Compliance: Leverage scalable, repeatable device templates to rapidly deploy firmware updates, operating systems, and core baseboard management controller (BMC/UEFI) simultaneously across multiple sites. XClarity One continuously analyzes hardware compliance, shifting out-of-compliance systems to a critical status until a template re-deployment aligns them back to corporate standards.
Global Asset Visibility and Fleet Telemetry: Centralize real-time tracking of component health, warranty status, and comprehensive hardware inventories. The platform aggregates live usage data, including memory allocation, power consumption, and processor thermal trends, giving you total operational awareness whether a server resides in a centralized data center or a remote edge environment.

Centralized management via Lenovo XClarity One can be integrated into your environment as an optional component. License information for XClarity One is listed in the following table.

Platform Firmware Resiliency - Lenovo ThinkShield

Lenovo's ThinkShield Security is a transparent and comprehensive approach to security that extends to all dimensions of our data center products: from development, to supply chain, and through the entire product lifecycle.

The ThinkSystem SR650 V4 includes Platform Firmware Resiliency (PFR) hardware Root of Trust (RoT) which enables the system to be NIST SP800-193 compliant. This offering further enhances key platform subsystem protections against unauthorized firmware updates and corruption, to restore firmware to an integral state, and to closely monitor firmware for possible compromise from cyber-attacks.

PFR operates upon the following server components:

UEFI image – the low-level server firmware that connects the operating system to the server hardware
XCC image – the management “engine” software that controls and reports on the server status separate from the server operating system
FPGA image – the code that runs the server’s lowest level hardware controller on the motherboard

The Lenovo Platform Root of Trust Hardware performs the following three main functions:

Detection – Measures the firmware and updates for authenticity
Recovery – Recovers a corrupted image to a known-safe image
Protection – Monitors the system to ensure the known-good firmware is not maliciously written

These enhanced protection capabilities are implemented using a dedicated, discrete security processor whose implementation has been rigorously validated by leading third-party security firms. Security evaluation results and design details are available for customer review – providing unprecedented transparency and assurance.

The SR650 V4 includes support for Secure Boot, a UEFI firmware security feature developed by the UEFI Consortium that ensures only immutable and signed software are loaded during the boot time. The use of Secure Boot helps prevent malicious code from being loaded and helps prevent attacks, such as the installation of rootkits. Lenovo offers the capability to enable secure boot in the factory, to ensure end-to-end protection. Alternatively, Secure Boot can be left disabled in the factory, allowing the customer to enable it themselves at a later point, if desired.

The following table lists the relevant feature code(s).

Lenovo Financial Services

Why wait to obtain the technology you need now? No payments for 90 days and predictable, low monthly payments make it easy to budget for your Lenovo solution.

Flexible

Our in-depth knowledge of the products, services and various market segments allows us to offer greater flexibility in structures, documentation and end of lease options.

100% Solution Financing

Financing your entire solution including hardware, software, and services, ensures more predictability in your project planning with fixed, manageable payments and low monthly payments.

Device as a Service (DaaS)

Leverage latest technology to advance your business. Customized solutions aligned to your needs. Flexibility to add equipment to support growth. Protect your technology with Lenovo's Premier Support service.

24/7 Asset management

Manage your financed solutions with electronic access to your lease documents, payment histories, invoices and asset information.

Fair Market Value (FMV) and $1 Purchase Option Leases

Maximize your purchasing power with our lowest cost option. An FMV lease offers lower monthly payments than loans or lease-to-own financing. Think of an FMV lease as a rental. You have the flexibility at the end of the lease term to return the equipment, continue leasing it, or purchase it for the fair market value. In a $1 Out Purchase Option lease, you own the equipment. It is a good option when you are confident you will use the equipment for an extended period beyond the finance term. Both lease types have merits depending on your needs. We can help you determine which option will best meet your technological and budgetary goals.

Ask your Lenovo Financial Services representative about this promotion and how to submit a credit application. For the majority of credit applicants, we have enough information to deliver an instant decision and send a notification within minutes.
