Thermal requirements by processor
For processors with a TDP of 320W or more (with some exceptions), the server must be configured as follows (one or both):
- Configure the closed-loop liquid-cooled heatsink (derived feature BSH6, enabled using feature BSWC), as described in the Closed-loop liquid-cooled heatsink section below
- Limit the drive backplanes used to only one of the 4-bay front drive backplanes (features BCGB or BPC9 as described in the Front drive bays section)
Exceptions to this rule (certain processor SKUs, drive-bay configurations, and ambient temperatures) are documented in the Thermal Rules section in the Lenovo Docs site for the SR635 V3:
https://pubs.lenovo.com/sr635-v3/thermal_rules
The SR635 V3 supports different processor heatsink solutions, depending on the configuration, as listed in the following table.
Feature code | Description |
---|---|
BQ26 | Performance heatsink - Neptune Thermal Transfer Module |
BSH6 | Closed-loop liquid-cooled heatsink - Neptune Liquid to Air Module |
The selection of the heatsink will be automatically derived by the configurator and depends on the processor and other components selected. Use the tables in the Lenovo Docs site to determine the requirements for each heatsink:
https://pubs.lenovo.com/sr635-v3/thermal_rules
Closed-loop liquid-cooled heatsink
The closed-loop liquid-cooled heatsink is primarily used for processors with a TDP of 320W or more. Without the closed-loop heatsink, the use of processors ≥ 320W TDP (except for 9654 and 9654P) requires that only 4x front 2.5-inch drive bays be configured. The use of the closed-loop heatsink allows for 10x SAS/SATA or NVMe drives bays.
The only exception to this rule is the use of the 9654 and 9654P 360W processors which allow the use of 10x 2.5-inch drive bays, provided the ambient temperature be no more than 25°C.
The following figure shows the placement of the components in the closed-loop system. A cold plate is mounted on top of the processor and it is connected via aluminum tubes to a radiator that is placed in front of the system fans. The tubes contain a mixture of water and ethylene glycol (EGW). The liquid is actively pumped through the pipes in a closed loop to remove the heat from the processors.
Figure 6. SR635 V3 with closed loop heatsink (feature BS34)
To enable closed-loop liquid-cooled heatsink in the DCSC configurator:
- In the Base tab, select Base as ThinkSystem V3 1U 10x2.5" Chassis (feature BLK4)
- Select Datacenter Environment of 25 Degrees Celsius (feature BL0H)
- In the Processor tab, select ThinkSystem SR635 V3 Neptune Liquid to Air Module (feature BSWC)
- Select a processor with TDP ≥ 320W
The closed-loop liquid-cooled heatsink has the following requirements:
- One of the following 2.5-inch front drive bay configurations:
- 10x 2.5" NVMe Gen4 (not Gen5)
- 10x 2.5" SAS/SATA
- 8x 2.5'' SAS/SATA
- 6x SAS/SATA + 4x AnyBay
- 6x SAS/SATA + 2x AnyBay + 2x NVMe
- EDSFF front drive bays are not supported
- If a RAID 940 or 9350 adapter is configured:
- RAID supercap must be installed in slot 3
- 7mm drives are not supported
- The following components are not supported:
- 256GB 3DS RDIMMs
- Rear 2.5-inch drives
- GPUs
- M.2 drives
- Any internal RAID/HBAs (CFF form factor)
For specific requirements, see the Thermal Rules page at https://pubs.lenovo.com/sr635-v3/thermal_rules.
UEFI operating modes
The SR635 V3 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.

9x4 RDIMMs (also known as Optimized or EC4 RDIMMs) are a new lower-cost DDR5 memory option supported in ThinkSystem V3 servers. 9x4 DIMMs offer the same performance as standard RDIMMs (known as 10x4 or EC8 modules), however they support lower fault-tolerance characteristics. Standard RDIMMs and 3DS RDIMMs support two 40-bit subchannels (that is, a total of 80 bits), whereas 9x4 RDIMMs support two 36-bit subchannels (a total of 72 bits). The extra bits in the subchannels allow standard RDIMMs and 3DS RDIMMs to support Single Device Data Correction (SDDC), however 9x4 RDIMMs do not support SDDC. Note, however, that all DDR5 DIMMs, including 9x4 RDIMMs, support Bounded Fault correction, which enables the server to correct most common types of DRAM failures.
For more information on DDR5 memory, see the Lenovo Press paper, Introduction to DDR5 Memory, available from https://lenovopress.com/lp1618.
The following rules apply when selecting the memory configuration:
- The SR635 V3 supports quantities 1, 2, 4, 6, 8, 10, 12 DIMMs per processor; other quantities not supported
- The server supports four types of DIMMs: 9x4 RDIMMs, 10x4 RDIMMs, x8 RDIMMs and 3DS RDIMMs; UDIMMs and LRDIMMs are not supported
- Mixing of DIMM types is not supported (for example, 9x4 DIMMs with 10x4 RDIMMs)
- Mixing x4 and x8 DIMMs is not supported
- Mixing of DIMM rank counts is supported. Follow the required installation order installing the DIMMs with the higher rank counts first.
- Mixing of DIMM capacities is supported, however only two different capacities are supported across all channels of the processor (eg 16GB and 32GB). Follow the required installation order installing the larger DIMMs first.
- The use of the 128GB 3D RDIMM feature BYEE has the following requirements for thermal reasons:
- Performance fans are required
- Rear 2.5-inch drives are not supported
- GPUs are not supported
- Additional ambient temperature requirements - see https://pubs.lenovo.com/sr635-v3/thermal_rules for information
Note: Memory mirroring and memory rank sparing are 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 12 memory channels with identical DIMMs (same Lenovo part number)
The following memory protection technologies are supported:
- ECC detection/correction
- Bounded Fault detection/correction
- SDDC (for x4-based memory DIMMs; look for "x4" in the DIMM description. Not supported with 9x4 RDIMMs)
- Patrol/Demand Scrubbing
- DRAM Address Command Parity with Replay
- DRAM Uncorrected ECC Error Retry
- On-die ECC
- ECC Error Check and Scrub (ECS)
- Post Package Repair
Internal storage
The SR635 V3 supports 12x 2.5-inch or 16x EDSFF drive bays, depending on the selected chassis and backplane configuration. The server also supports configurations without any drive bays if desired.
No 3.5-inch drive bay support: The SR635 V3 does not support configurations with 3.5-inch drive bays.
The two drive bay zones are as follows:
- Front:
- Up to 10x 2.5-inch hot-swap bays, or
- 16x EDSFF hot-swap bays
- Rear:
- 2x 2.5-inch hot-swap bays, or
- 2x 7mm hot-swap drives bays
All drives are hot-swap and are accessible from the front or from the rear.
The server also supports one or two M.2 drives, installed in an M.2 adapter internal to the server.
In this section:
NVMe drive support
The SR635 V3 supports NVMe drives to maximize storage performance:
- In 2.5-inch front drive configurations, the server supports up to 12 NVMe drives without oversubscription (that is, each x4 drive has a dedicated x4 connection (4 lanes) to the processor):
- 10x 2.5-inch NVMe drives at the front
- 2x 2.5-inch NVMe drives at the rear
- In EDSFF front drive configurations, the server supports up to 16 NVMe drives without oversubscription:
- 16x E1.S NVMe drives at the front
The specifics of these configurations are covered in the Storage configurations section.
In addition, the SR635 V3 supports two 7mm NVMe drives for use as boot drives. These two drives optionally support RAID via a separate RAID adapter installed in a PCIe slot.
The RAID 940-8i and RAID 940-16i adapters also 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. 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 in either 2.5-inch and 3.5-inch form factor 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.

Field upgrades
The SR635 V3 is orderable without drive bays, allowing you to add a backplane, cabling and controllers as field upgrades.
In this section:
- 2.5-inch, 3.5-inch and EDSFF field upgrades
- Upgrades to an Internal (CFF) HBA/RAID adapter
- 7mm drive bay field upgrades
2.5-inch, 3.5-inch and EDSFF field upgrades
Rear backplane kits included cables, however for front drive bays, the backplane kits do not include cables and must be ordered separately. The following table summarizes the option part numbers you will need to order for each available drive configuration.
For more information about the backplane kits and cable kits, see the Lenovo Server Options site:
https://serveroption.lenovo.com/cable_kit_options/
Tip: There is no upgrade path to add drive bays if the SR635 V3 already has a backplane, without removing the existing backplane. For example, you cannot upgrade a 4x 2.5-inch drive bay to 8 bays without first removing the existing backplane.

RAID flash power module (supercap) support
If you plan to add one of the RAID adapters that includes a RAID flash power module (supercap) as a field upgrade, then you will also need to order a supercap installation kit for the power module. For CTO orders, the components in the installation kit are automatically derived when you select the RAID adapter.
The adapters that this applies to are as follows:
- Any supported RAID 9350 adapter
- Any supported RAID 940 adapter (including 940 adapters with external ports)
There are three possible locations for supercaps. Details are summarized in the following table. Location references are shown in the figure below.
Processor heatsinks | Number of adapters & supercaps |
Locations of supercaps |
---|---|---|
High performance heatsink | 3* |

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 2 supercaps 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.
- 7mm drive support: The storage adapters listed in the table below do not provide connectivity to the 7mm drive bays that are optionally available at the rear of the server. The 7mm drives have their own independent RAID controller. See the Rear 2.5-inch and 7mm drive bays section for details.
- E810 Ethernet and X350 RAID/HBAs: The use of both an Intel E810 network adapter and an X350 HBA/RAID adapter (9350, 5350 and 4350) is currently not supported in ThinkSystem servers. For details see Support Tip HT513226. Planned support for this combination of adapters is 4Q/2023 (SI 23-2).
The RAID 940-8i and RAID 940-16i adapters also 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. 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 in either 2.5-inch and 3.5-inch form factor 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.
The onboard SATA controller has the following features:
- Controller integrated into the AMD processor
- JBOD only; no RAID support
- Supports up to 12 SATA drives in the SR635 V3
- Supports HDDs and SSDs; can be mixed
The onboard NVMe support has the following features:
- Controller integrated into the AMD processor
- Supports up to 16 NVMe drives direct connected to onboard ports
- Each drive has PCIe x4 host interface, up to PCIe Gen5 depending on the backplane and drive type
- Supports JBOD only - No RAID support
For specifications about the RAID adapters and HBAs supported by the SR635 V3, see the ThinkSystem RAID Adapter and HBA Reference, available from:

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 |
---|---|---|
7XA7A05926 | AVV8 | ThinkSystem External USB DVD RW Optical Disk Drive |
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 SR635 V3 supports a total of up to 5x PCIe slots, 3x at the rear and 2x at the front, plus 1x OCP 3.0 SFF slot for networking. The OCP slot can be either at the front or rear. Slot availability is based on riser selection and drive bays configured.
Topics in this section:
Rear slots
The following figure shows the locations of the rear-accessible and front-accessible slots for each configuration selection. The OCP slot is located below the PCIe slots.
Figure 11. SR635 V3 slot configurations
The rear-accessible slots and riser cards are as follows:
- Riser 1: Slots 1 & 2
- Slot 1: Low Profile, PCIe x16
- Slot 2: Low Profile or FHHL, PCIe x16 (only in configuration A, B, and E in the above figure)
- Riser 2: Slot 3
- Slot 3: Low Profile or FHHL, PCIe x16 (only in configuration A and C)
Depending on the riser selected, the slots are either PCIe Gen4 or PCIe Gen5. Some configurations are only available with Gen4 slots.
The following table lists the configuration and ordering information for the PCIe slots in the SR635 V3. The Cfg column matches the slot configurations shown in the preceding figure. The table is divided up into configurations with Gen5 slots with Gen4, and configurations with only Gen4 slots. Ordering information is as follows:
- For CTO orders, order the feature codes listed for the configuration, both riser and cage feature codes (2 or 4 feature codes, depending on the configuration)
- For field upgrades, order the part numbers listed for the configuration (1 or 2 part numbers, depending on the configuration). The part numbers include both the risers and cages needed for that configuration.
It is also possible to build a configuration without any slots, in which case slot fillers will be derived in the configurator. Slots can be added later as field upgrades using option part numbers as listed in the Field upgrades table.
Maximum 2x Gen5 slots: The maximum number of PCIe slots is 2, by selecting configuration C (LP + FH). It is not currently possible to configure 3x PCIe Gen5 low-profile slots, configuration A.

Supported power supplies are auto-sensing dual-voltage units, supporting both 110V AC (100-127V 50/60 Hz) and 220V AC (200-240V 50/60 Hz) power. For China customers, all power supplies support 240V DC. All supported AC power supplies have a C14 connector.
The supported -48V DC power supply has a Weidmuller TOP 4GS/3 7.6 terminal as shown in the following figure.
Figure 14. Connector on the ThinkSystem 1100W -48V DC Hot-Swap Gen2 Power Supply
Power supply options do not include a line cord. For server configurations, the inclusion of a power cord is model dependent. Configure-to-order models can be configured without power cords if desired.
Power supply LEDs
The supported hot-swap power supplies have the following LEDs:
- Power input LED:
- Green: The power supply is connected to the AC power source
- Off: The power supply is disconnected from the AC power source or a power problem has occurred
- Power output LED:
- Green: The server is on and the power supply is working normally
- Blinking green: The power supply is in Zero-output/Standby mode (see below)
- Off: The server is powered off, or the power supply is not working properly
- Power supply error LED:
- Off: The power supply is working normally
- Yellow: The power supply has failed
Zero-output mode: When Zero-output mode (also known as Standby mode or Cold Redundancy 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.
Power cords
Line cords and rack power cables with C13 connectors can be ordered as listed in the following table.
110V customers: If you plan to use the 1100W power supply with a 110V power source, select a power cable that is rated above 10A. Power cables that are rated at 10A or below are not supported with 110V power.

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 SR635 V3 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 SR635 V3 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).
Part number | Feature code | Description | Purpose |
---|---|---|---|
CTO only | BPKQ | TPM 2.0 with Secure Boot | Configure the system in the factory with Secure Boot enabled. |
CTO only | BPKR | TPM 2.0 | Configure the system without Secure Boot enabled. Customers can enable Secure Boot later if desired. |
Tip: If Secure Boot is not enabled in the factory, it can be enabled later by the customer. However once Secure Boot is enabled, it cannot be disabled.
