† The maximum single-core frequency that the processor is capable of operating

Thermal requirements by processor

In the SR655 V3, the processor either uses a standard heatsink or a performance heatsink depending on the TDP of the processor. Performance heatsinks include two satellite heatsinks that connect to the main heatsink via liquid filled copper tubes.

Additional ambient temperature restrictions may apply. See the Operating environment section for details.

UEFI operating modes

The SR655 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.

Table 10. UEFI operating mode presets in DCSC
Feature code Description
BFYA Operating mode selection for: "Maximum Efficiency Mode"
BFYB Operating mode selection for: "Maximum Performance Mode"

The preset modes for the SR655 V3 are as follows:

  • Maximum Efficiency Mode (feature BFYA): Maximizes performance/watt efficiency while maintaining reasonable performance
  • Maximum Performance Mode (feature BFYB): Achieves maximum performance but with higher power consumption and lower energy efficiency.

For details about these preset modes, and all other performance and power efficiency UEFI settings offered in the SR655 V3, see the paper "Tuning UEFI Settings for Performance and Energy Efficiency on AMD Processor-Based ThinkSystem Servers", available from https://lenovopress.lenovo.com/lp1267.

Platform Secure Boot

Platform Secure Boot (PSB) is a feature of AMD EPYC processors that helps defend against threats to firmware. It is designed to provide protection in response to growing firmware-level remote attacks being seen across the industry. AMD Secure Boot extends the AMD silicon root of trust to help protect the system by establishing an unbroken chain of trust from the AMD silicon root of trust to the BIOS. The UEFI secure boot helps continue the chain of trust from the system BIOS to the OS Bootloader. This feature helps defend against remote attackers seeking to embed malware into firmware.

With PSB enabled, the processor is cryptographically bound to the server firmware code signing key once the processors are installed in the server and the server is powered on. From that point on, that processor can only be used with motherboards that use the same code signing key.

Disabling PSB will stop the protection against remote and local attackers seeking to embed malware into a platform’s firmware, BIOS and even UEFI functions. Disabling PSB also allows you to install the processor in another server that you purchased from Lenovo, however, we do not recommend you do this by yourself. Please contact the Lenovo service team for further assistance. 

By default, the server has Platform Secure Boot enabled on the installed processors, however for factory orders, you can choose to have the server with PSB disabled. To do this, select the feature code listed in the following table. PSB can be later enabled in System Setup if desired.

Cannot be disabled once enabled: Once you enable PSB in a server, it cannot be disabled on those processors.

Table 11. Platform Secure Boot
Feature code Description Purpose
C18D Platform Secure Boot Disable PSB is not enabled in the factory. It can be later enabled in UEFI System Setup if desired.

If you add a second processor as a field upgrade and your server has PSB enabled, then as soon as you install the processor and power the server on, the processor is then cryptographically bound to the server, and can only be used in that server going forward.

Note: Platform Secure Boot (PSB) is different from the Secure Boot security feature described in the Platform Firmware Resiliency section.

Memory options

The SR655 V3 uses Lenovo TruDDR5 memory operating at up to 4800 MHz. The server supports up to 12 DIMMs. The processor has 12 memory channels and supports 1 DIMM per channel. The server supports up to 3TB of memory using 12x 256GB 3DS RDIMMs.

The following table lists the memory options that are available for the server.

Lenovo TruDDR5 memory uses the highest quality components that are sourced from Tier 1 DRAM suppliers and only memory that meets the strict requirements of Lenovo is selected. It is compatibility tested and tuned to maximize performance and reliability. From a service and support standpoint, Lenovo TruDDR5 memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.

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 SR655 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 128GB 3DS RDIMMs and 256GB 3DS RDIMMs 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.

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 SR655 V3 has three drive bay zones and supports up to 20x 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 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
  • Middle:
    • 4x 3.5-inch hot-swap bays, or
    • 8x 2.5-inch hot-swap bays
  • Rear:
    • Up to 4x 3.5-inch hot-swap bays, or
    • Up to 8x 2.5-inch hot-swap bays
    • Also supports 2x 7mm hot-swap drives bays

All drives are hot-swap and are accessible from the front, from the rear, or from drive bays that are located in the middle of the server (accessible when you remove the top cover of the server).

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 SR655 V3 supports NVMe drives to maximize storage performance.

  • Up to 24 NVMe drives in a 2.5-inch drive configuration, without oversubscription (that is, each x4 drive has a dedicated x4 (4 lanes) connection to the processor, either direct to the processor or via a retimer adapter)
    • Up to 24 installed in front bays
  • Up to 32 NVMe drives in a 2.5-inch drive configuration, with oversubscription (using NVMe switch adapters)
    • 24 installed in front bays
    • 8 installed in mid-chassis bays
  • Up to 8 NVMe drives in a 3.5-inch drive configuration, without oversubscription
    • All installed in mid bays

Riser 3 support: The use of the onboard NVMe ports is mutually exclusive with Riser 3, as these use the same PCIe connectors. See the System architecture 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.

In addition, the SR655 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. 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 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.

Front drive bays

The front drive bay zone supports the following configurations:

  • 8x or 12x 3.5-inch drive bays (all hot-swap)
  • 8x, 16x or 24x 2.5-inch drive bays (all hot-swap)
  • 4x 2.5-inch drive bays (all hot-swap) with support for front PCIe slots (planned for 2Q/2023)
  • No backplanes and no drives (supports field upgrades)

The specific combinations that are supported in the SR655 V3 are shown in the following figures. The feature codes listed in the figures are the backplane feature codes when ordering CTO and correspond to the feature codes listed in the table below the figure. In the figures, G4 refers to PCIe Gen4 and G5 refers to PCIe Gen5.

* Backplane has an onboard SAS expander that provides connectivity to SAS/SATA drive bays in a separate rear backplane (order the rear backplane separately). See also note below for BQ2T.

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

  • The SR655 V3 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
  • Any 8x 2.5-inch and 16x 2.5-inch drive configuration (SAS/SATA, AnyBay, or NVMe) can optionally be configured for use with the Integrated Diagnostics Panel as described in the Local management section. 3.5-inch drive configurations do not support the Integrated Diagnostics Panel. With the Integrated Diagnostics Display, 8-bay configurations can be upgrade to 16 bays, however 16-bay configurations cannot be upgrade to 24 bays.
  • If you are building a server configuration that includes the ThinkSystem 2U 24x2.5" SAS/SATA with Rear 4-Bay Expander Backplane (feature BQ2T) and the order also includes a rack cabinet, then you can configure at most 6 drives to be installed in the factory. The remaining drives must be ordered separately using the option part numbers for the drives. This requirement does not apply if the order does not include a rack cabinet. The requirement is due to the shock/vibration limits of the 24x 2.5-inch backplane.

Mid drive bays

The SR655 V3 supports hot-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:

  • 4x 3.5-inch hot-swap SAS/SATA drive bays
  • 8x 2.5-inch hot-swap SAS/SATA drive bays
  • 8x 2.5-inch hot-swap NVMe drive bays

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

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 and 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 T4) are not supported
  • The use of mid drive bays may require Riser 1 or Riser 2 be installed, since power for the mid bay backplanes comes from a riser

Rear drive bays

The SR655 V3 supports hot-swap drives installed at the rear of the server chassis. Supported configurations are as follows:

  • 3.5-inch hot-swap drives
    • 2x SAS/SATA drive bays
    • 4x SAS/SATA drive bays
  • 2.5-inch hot-swap drives
    • 4x SAS/SATA drive bays
    • 4x AnyBay drive bays
    • 8x SAS/SATA drive bays

The configurations are shown in the following figure.

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.

In addition, the server supports two 7mm-thickness hot-swap SSDs which are installed in place of either slot 3 or slot 6 (not both). These 7mm drives can be used in conjunction with any rear drive 2.5-inch or 3.5-inch bay combination. See the 7mm drives section for details.

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

  • The use of rear bays restricts the number of slots and the choice of risers that are supported. See the I/O expansion section for details.
  • The 7mm rear drive kit is supported in either slot 3 or slot 6 but not both at the same time.
  • The 7mm drive enclosure is connected to an onboard connectors and cannot be connected to any installed RAID adapter or HBA.

Storage configurations

This section describes the various combinations of front and rear drives that the server supports, as well as M.2 support.

Field upgrades

The SR655 V3 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).

For more information about the backplane kits and cable kits, see the Lenovo server options site:
https://serveroption.lenovo.com/cable_kit_options/

The upgrades are listed as follows:

2.5-inch and 3.5-inch chassis drive bay upgrades

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

In the case of 8x2.5" backplanes, there are cable kits for BP1, BP2 and BP3, which correspond to the backplanes as shown in the following figure. Select the cables related to the backplane location you wish to upgrade.

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.

Upgrades to Retimer adapters

If you are upgrading to a configuration that includes a Retimer adapter (see the Detailed tables in the Storage configurations section), then you will need to also order one of the following cable kits.

Table 21. Cable kits when upgrading to a Retimer configuration
Part number Description Quantity
required
4X97A86434 ThinkSystem SR655 V3 24 NVMe Cable Kit 1
4X97A86435 ThinkSystem SR655 V3 32 NVMe Cable Kit 1

Upgrades to an Internal (CFF) HBA/RAID adapter

If you want to add an internal (CFF) storage adapter (HBA, RAID adapter or SAS expander) to a configuration, you will need to order the cable kit as listed in the following table. Suitable upgrades are either replacing an existing adapter in a rear PCIe slot, or adding the CFF adapter to a server without any storage adapter installed.

The cable kit to order is listed in the following table.

Table 22. Cable kit when upgrading to an Internal HBA/RAID adapter
Part number Description Quantity
required
4X97A86433 ThinkSystem SR655 V3 Internal Raid Adapter Cable Kit 1

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 may also need to order a Supercap installation kit for the supercap, depending on the location where the supercap will be installed. For CTO orders, the components needed 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

The location of the supercaps depends on the mid-chassis drive cage used in the server, as shown in the following table.

Table 23. Supercap support
Mid drive cage Supercaps
supported		 Location of supercaps Supercap holder
No mid drive cage 4 Mounted on the air baffle Not needed
2.5-inch drives 2 Mounted on the left side of the mid drive cage Integrated into the left side of the 2.5-inch mid drive cage
3.5-inch drives 1 Mounted under the system fan cage Included with ThinkSystem SR655 V3 4x3.5" SAS/SATA Middle Backplane Option Kit (4XH7A86758) or order separately (see below)

For 3.5-inch drive bay configurations, if the server already has 3.5-inch mid-chassis drive bays, then the supercap holder is already present under the system fan cages. If you plan to add 3.5-inch mid-chassis drive bays by adding ThinkSystem SR655 V3 4x3.5" SAS/SATA Middle Backplane Option Kit (4XH7A86758), then the supercap holder is part of the option kit.

7mm drives

The SR655 V3 supports two 7mm drives, either both SATA or both NVMe, at the rear of the server. These drives go in place of either PCIe slot 3 (Riser 1) or PCIe slot 6 (Riser 2) as shown in the following figure.

SR665 rear 7mm drive bay configurations
Figure 13. Rear 7mm drive bay configurations

For CTO orders, the configuration includes the drive bays and the cage the the drive bays are mounted on to.The cage required depends on where the 7mm drives are located (Riser 1 or Riser 2) and whether there are PCIe slots above the 7mm drive bays. The following table lists the ordering information.

Tip for 4x 3.5-inch rear drives: If you wish to configure 4x 3.5-inch rear drives plus 7mm drives in a CTO configuration, the 7mm drives will install in slot 6. You should specify riser card BLKP for Riser 1 and then leave Riser 2 without a riser selected.

‡ These custom form factor (CFF) adapters are only supported with 2.5-inch front drive bays. Not supported in configurations with 3.5-inch front drive bays.
† Adapter also supports PCIe 4.0 x1 connectivity to NVMe drives (requires 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 4 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.
  • 7mm drive support: The storage adapters listed in the table below do not provide connectivity to the 7mm drive bays. The 7mm drives have their own independent RAID controller. See the 7mm drives 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 2Q/2024.

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. 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 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 16 SATA drives in the SR655 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 12 NVMe drives direct connected to onboard ports; additional drives through retimer/switch adapters
  • Each drive has PCIe 5.0 x4 host interface
  • Supports JBOD
  • No support for RAID

For specifications about the RAID adapters and HBAs supported by the SR655 V3, see the ThinkSystem RAID Adapter and HBA Reference, available from:
https://lenovopress.lenovo.com/lp1288-thinksystem-raid-adapter-and-hba-reference#sr655-v3-support=SR655%2520V3

Internal drive options

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

2.5-inch hot-swap drives:

2.5-inch 7mm hot-swap drives:

3.5-inch hot-swap drives:

M.2 drives:

M.2 drive support: The use of M.2 drives requires an additional adapter as described in the M.2 drives subsection.

SED support: The tables include a column to indicate which drives support SED encryption. The encryption functionality can be disabled if needed. Note: Not all SED-enabled drives have "SED" in the description.

USB memory key

For general portable storage needs, the server also supports the USB memory key option that is listed in the following table.

Table 48. USB memory key
Part number Feature Description
4X77A77065 BNWN ThinkSystem USB 32GB USB 3.0 Flash Drive

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.

Table 49. External optical drive
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 server supports up to 10x total PCIe slots, plus a slot dedicated to the OCP adapter (rear or front). The 10x slots are either 10x rear-facing slots, or a combination of 6x rear + 2x front PCIe slots.

The server also offers a dedicated OCP 3.0 SFF slot for networking, located either at the rear or front of the server. Slot availability is based on riser selection.

Topics in this section:

Slot layout and connections

The slots at the rear are provided by riser cards as follows:

  • Riser 1: Slots 1, 2 and 3, all full-height slots
  • Riser 2: Slots 4, 5, and 6, all full-height slots
  • Riser 3: Slot 7 and 8
    • Without Riser 4: both full-height slots
    • With Riser 4: both low-profile slots
  • Riser 4: Slots 9 and 10, both low-profile slots

The slots in each riser are either PCIe x16 or PCIe x8 depending on the riser card selected as listed in the table below. All x8 slots are open-ended and physically support x16 adapters. Depending on the risers selected, slots are either PCIe 5.0 or PCIe 4.0. OCP slot is PCIe 4.0 x16.

The SR655 V3 also supports front-accessible PCIe slots: 2x PCIe 4.0 x16 slots plus a dedicated OCP 3.0 SFF slot (PCIe 4.0 x16) for networking. When front slots are used, rear slots 7-10 (Riser 3 & Riser 4) are not available as they use the same connectors. Front-accessible slots are as follows:

  • Slot 11: PCIe 4.0 x16 FHHL
  • Slot 12: PCIe 4.0 x16 FHHL

Onboard NVMe support: When Riser 3 (or Riser 3+4) is configured, only 4 NVMe drives can be connected using onboard NVMe connectors. 

As discussed in the Internal storage section, the server supports drive bays in the rear of the server. Depending on the drive bays selected, the number of slots available for adapters is reduced. The figure below shows the supported combinations of slots and drive bays.

Internal HBA/RAID adapter: For configurations with 2.5-inch front drive bays, an internal RAID adapter or HBA can be installed in a dedicated space and cabled to a PCIe x8 connector, thereby freeing up a slot for other purposes.

The following figure shows the locations of the rear-accessible slots for each configuration selection. The OCP slot in located in the lower-left corner.

SR655 V3 slots
Figure 14. SR655 V3 rear slot configurations

The following figure shows the locations of the front-accessible slots.

SR655 V3 front slots
Figure 15. SR655 V3 front slots

Ordering information

The following table lists the riser cards available for CTO builds and for field upgrades.

No slots: 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 table.

* All PCIe x8 slots are open ended and will physically support x16 adapters
† In the configurator, when feature BQ2W is selected, BTMS is automatically derived and provides slots 9 & 10. 4XH7A87546 contains both risers. Note that in the SR655 V3, risers BQ2W and BTMS supply Gen4 slots, not Gen5, even though the feature codes are named "Gen5".
‡ When selecting the front riser BQ2X, you will also need to select feature BQB4 (ThinkSystem V3 2U Front I/O Module in the Others section of the configurator.

Configuration rules:

  • For best performance, install PCIe 5.0 adapters in PCIe 5.0 (Gen5) slots
  • The server only supports one OCP slot, either in the rear of the server or the front of the server, not both
  • Front slots are supported only with rear slots in Riser 1 and 2. Front slots cannot be used in combination with Riser 3 (or Riser 4) as they use the same connectors.
  • If you want to configure 4x low profile slots for slots 7-10, select feature BQ2W which provides riser 3 (slots 7, 8). Feature BTMS will then be automatically derived to provide riser 4 (slots 9 & 10), along with the necessary cables. Option part number 4XH7A87546 contains both of these risers and the cables.
  • If you want to add both a 7mm drive enclosure plus 2x PCIe slots above it, you will need to order the 7mm drive option (either 4XH7A85898 or 4XH7A85899) plus the x16/x16/E riser kit (4XH7A82900 for PCIe Gen 5 or 4XH7A82892 for Gen 4). The riser kit part number provides the 2-slot riser card.
  • All PCIe x8 slots are open ended and will physically support x16 adapters
  • To support Riser 3 (or Riser 3+4), the following must both apply:
    • No rear drives are configured
    • If the Onboard NVMe ports are used, then no more than 4 NVMe or AnyBay drive bays are configured (eg a 3.5-inch backplane of 8x SAS/SATA + 4x AnyBay is supported, or a 2.5-inch backplane of 6x SAS/SATA + 2x AnyBay is supported)
  • In the configurator, when you configure front PCIe slots, you will need to select two separate components:
    • ThinkSystem V3 2U Front x16/x16 PCIe G4 Riser, BQ2X (from the PCIe > Risers tab in DCSC)
    • ThinkSystem V3 2U Front I/O Module, BQB4 (from the Other tab in the Front IO section in DCSC)

Serial port

The SR655 V3 optionally supports a RS-232 serial port by adding a COM port bracket to either slot 3 or slot 6. Ordering information is shown in the following table.

Configuration requirements:

  • Adapters with a x16 host interface require a x16 slot to maximize performance
  • PCIe Gen5 adapters will require a Gen5 riser to maximize performance
  • 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 2Q/2024.

The RAID 940-8e uses a flash power module (supercap), which can be installed in one of up to four locations in the server depending on the server configuration. See the RAID flash power module (supercap) support section for details. The number of 940-8e RAID adapters supported is based on how many supercaps can be installed in the server. If an internal RAID adapter with flash power modules is installed, the maximum number of 940-8e adapters supported is reduced by 1.

For information about these GPUs, see the ThinkSystem GPU Summary, available at:
https://lenovopress.com/lp0768-thinksystem-thinkagile-gpu-summary

For CTO orders, the SR655 V3 also supports the selection of a placeholder for a GPU. This selection results in a "GPU ready" configuration which ensures that the server ships with the components needed for GPU installation (GPU power cables, air ducts, power supplies, fans, etc) without actually including the GPUs themselves. The following table lists the ordering information for CTO orders.

CTO only BVLL ThinkSystem NVIDIA H100 GPU-Ready Installation
CTO only BP4X ThinkSystem DW GPU-Ready Installation (for all other supported DW GPUs)

Configuration rules

The following configuration requirements must be met when installing GPUs:

  • Some NVIDIA A Series GPUs are available as two feature codes, one with a CEC chip and one without a CEC chip (ones without the CEC chip have "w/o CEC" in the name). The CEC is a secondary Hardware Root of Trust (RoT) module that provides an additional layer of security, which can be used by customers who have high regulatory requirements or high security standards. NVIDIA uses a multi-layered security model and hence the protection offered by the primary Root of Trust embedded in the GPU is expected to be sufficient for most customers. The CEC defeatured products still offer Secure Boot, Secure Firmware Update, Firmware Rollback Protection, and In-Band Firmware Update Disable. Specifically, without the CEC chip, the GPU does not support Key Revocation or Firmware Attestation. CEC and non-CEC GPUs of the same type of GPU can be mixed in field upgrades.
  • All GPUs installed must be identical
  • When a double-wide GPU is installed in slot 2, 5 or 7, the adjacent slot 1, 4 and 8 respectively is not available
  • Flash storage adapters are not supported.
  • Middle drive bays and Rear drive bays are not supported
  • GPUs are not supported with CPUs with a TDP of more than 300W

For additional requirements related to GPUs, see the GPU Configuration section of the Thermal Rules page in the Information Center:
https://pubs.lenovo.com/sr655-v3/thermal_rules

Riser selections for double-wide GPUs

When a double-wide GPU is installed in slot 2, 5 or 7, the adjacent slot 1, 4 and 8 respectively is not available. The riser cards listed in the following table are used with double-wide GPUs.

GPU cable kits

The following cable kits are offered to provide auxiliary power cables for GPUs that require one. See the Supported GPUs table to see which GPUs require an auxiliary power cable.

Configuration notes:

  • This cable kits are only required for field upgrades; factory (CTO) orders will automatically include any required cables.
  • For double-wide GPUs, The DW (double-wide) cable kit is only required if you are adding additional double-wide GPUs to a server that already has a DW GPU installed from a CTO order. If you are doing a field upgrade to install the first DW GPU to a server, order the ThinkSystem SR655 V3 GPU Enablement Kit, 4X67A86438 instead, since the Enablement Kit includes the necessary power cables.
  • The SW (single-wide) cable kit is required if you are doing any field upgrades to add a single-wide GPU that requires an auxiliary power cable (GPU power > 75 W), however, all currently supported GPUs do not require auxiliary power cables.

Cooling

The SR655 V3 server has up to six 60 mm hot-swap variable-speed fans. The server offers N+1 redundancy. The server also has one or two additional fans integrated in each of the two power supplies. Most configurations require 6 system fans. If Riser 3 is not configured, then only 4 system fans are needed.

Depending on the configuration, the server will need either Standard fans (single-rotor 17K RPM) or Performance fans (dual-rotor 21K RPM).

Under all of the following conditions, standard fans can be used:

  • CPU with TDP ≤ 240W
  • No GPUs
  • No 100GbE or higher network adapters
  • No 3DS RDIMMs
  • Front drive bays not 12x 3.5-inch
  • No mid-chassis drive bays
  • No rear drive bays

If any conditions are not met, Performance fans are required.

Ordering information for the fans is listed in the following table.

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.

AC power supplies up to 1800W have a C14 connector. AC power supplies 2400W and above have a C19 connector.

The supported -48V DC power supply has a Weidmuller TOP 4GS/3 7.6 terminal as shown in the following figure.

ThinkSystem 1100W -48V DC v2 Power Supply
Figure 18. 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 SR655 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 SR655 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).

Table 77. Secure Boot options
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.

  • Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels in your installation depend upon a variety of factors, including the number of racks in the installation; the size, materials, and configuration of the room; the noise levels from other equipment; the room ambient temperature, and employee's location in relation to the equipment. Further, compliance with such government regulations depends on a variety of additional factors, including the duration of employees' exposure and whether employees wear hearing protection. Lenovo recommends that you consult with qualified experts in this field to determine whether you are in compliance with the applicable regulations.
