Tip: Some HPC and AI models are not listed in DCSC and can only be configured in x-config.

Controlled GPU models: The "Controlled GPU" base CTO models listed in the table are the only models that support high-performance GPUs and accelerators. These models are classified under US Government ECCN regulations and have limited market and customer availability. All other base models do not support high-performance GPUs.

Preconfigured server models may also be available for the SR645 V3, 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 SR645 V3 server.

Thermal requirements by processor

For thermal requirements for processors, see the Thermal Rules section in the Lenovo Docs site for the SR645 V3:
https://pubs.lenovo.com/sr645-v3/thermal_rules

The SR645 V3 supports three different processor cooling solutions, depending on the configuration, as listed in the following table.

Table 14. Processor cooling options
Feature code Description Purpose
BQ26 ThinkSystem SR645 V3/SR635 V3 1U High Performance Heatsink (Neptune Thermal Transfer Module) Performance 1U heatsink with two satellite heatsinks. Automatically selected based on the server configuration.

BZGM ThinkSystem V3 Neptune Processor Direct Water Cooling Solution Enables open-loop liquid cooling of the processors. See the Lenovo Neptune Processor DWC Module section.

Lenovo Neptune Liquid to Air Module - Closed-loop liquid cooling

The Lenovo Neptune Liquid to Air (L2A) Module is a closed-loop liquid-cooled processor heatsink, and is primarily used for processors with a high TDP.

The use of the closed-loop heatsink allows the following configurations that the performance heatsink cannot support:

  • 9384X/9184X/9274F/9374F/9474F processors in the 2.5-inch chassis
  • 9684X processors with a 8x2.5-inch or 10x2.5-inch front drive backplane
  • 9734/9754 processors with a 10x2.5-inch front drive backplane
  • Support for up to 30°C ambient for all Group E processors (320W ≤ TDP ≤ 400W)

The following figure shows the placement of the components in the closed-loop liquid-cooled solution. Cold plates are mounted on top of each processor and these are 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.

SR645 V3 with closed water loop
Figure 7. SR645 V3 with closed water loop (feature BS34)

The Neptune Liquid to Air Module is only available in CTO orders, not as a field upgrade. Ordering information is listed in the following table.

Table 15. Ordering information

https://pubs.lenovo.com/sr645-v3/thermal_rules

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

Lenovo Neptune Processor DWC Module - Open-loop liquid cooling

The SR645 V3 also supports advanced direct-water cooling (DWC) capability with the Lenovo Neptune Processor DWC 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 distrubution units.

With the Neptune Processor DWC 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.

The following figure shows the Lenovo Neptune Processor DWC Module.

Lenovo Neptune Processor DWC Module
Figure 8. Lenovo Neptune Processor DWC Module

The Neptune Processor DWC 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.

The Neptune Processor DWC Module is only available in CTO orders, not as a field upgrade. Ordering information is listed in the following table.

Table 16. Ordering information

UEFI operating modes

The SR645 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 17. 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 SR645 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 SR645 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 feature code C18D as 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 18. Platform Secure Boot
Feature code Description Purpose
C0DF Platform Secure Boot Enable PSB is enabled in the factory and cannot later be disabled. Default choice in DCSC.
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 SR645 V3 uses Lenovo TruDDR5 memory operating at up to 4800 MHz. The server supports up to 24 DIMMs with 2 processors. The processors have 12 memory channels and support 1 DIMM per channel. The server supports up to 6TB of memory using 24x 256GB 3DS RDIMMs and two processors.

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 SR645 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 of DRAM technology (16Gb and 24Gb) is not supported. See the column in the above table.
  • Mixing of 128GB 3DS RDIMMs and 256GB 3DS RDIMMs is not supported
  • Mixing of 128GB 3DS RDIMMs (features BYEE and BQ3A) is not supported
  • Mixing of 256GB 3DS RDIMMs (features BZPN and BQ3B) is not supported
  • 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:

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 SR645 V3 supports 4x 3.5-inch or 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.

The two drive bay zones are as follows:

  • Front:
    • 4x 3.5-inch hot-swap bays, or
    • 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 SR645 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 3.5-inch front drive configurations, the server supports up to 6 NVMe drives without oversubscription:
    • 4x 3.5-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 SR645 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 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. All drives are hot-swap.

  • 3.5-inch hot-swap drive bays
    • 4x SAS/SATA 3.5-inch
    • 4x AnyBay 3.5-inch (PCIe Gen4)
    • 2x SATA + 2x SATA/NVMe 3.5-inch (PCIe Gen4)
  • 2.5-inch hot-swap drive bays without support for front PCIe slots
    • 4x SAS/SATA
    • 4x NVMe (PCIe Gen4 or Gen5)
    • 8x SAS/SATA
    • 10x SAS/SATA
    • 6x SAS/SATA + 4x AnyBay (PCIe Gen4 or Gen5)
    • 6x SAS/SATA + 2x AnyBay + 2x NVMe (PCIe Gen4 or Gen5)
    • 10x AnyBay (PCIe Gen4 or Gen5)
    • 10x NVMe (PCIe Gen4 or Gen5)
  • 2.5-inch hot-swap drive bays with support for front PCIe slots
    • 2x NVMe (PCIe Gen4)
    • 4x NVMe (PCIe Gen4 or Gen5)
    • 4x AnyBay (PCIe Gen5)
  • EDSFF drive bays
    • 16x E1.S (9.5mm or 15mm) hot-swap NVMe drive bays (PCIe Gen4)
  • Drive-less 2.5-inch configuration - No backplane and no drives (supports field upgrades)
  • Drive-less 3.5-inch configuration - No backplane and no drives (supports field upgrades)

These configurations are shown in the following three figures. The feature codes listed correspond to the feature codes listed in the table below the figures.

Field upgrades for drive bays

The SR645 V3 is orderable without drive bays, allowing you to add a backplane, cabling and controllers as 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 SR645 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.

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.

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 only 1 supercap, the location of which depends on the server configuration as described in the RAID flash power module (supercap) support section. The number of supercaps supported 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 3Q/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 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 SR645 V3
  • Supports HDDs and SSDs; can be mixed

For specifications about the RAID adapters and HBAs supported by the SR645 V3, see the ThinkSystem RAID Adapter and HBA Reference, available from:
https://lenovopress.lenovo.com/lp1288-thinksystem-raid-adapter-and-hba-reference#sr645-v3-support=SR645%2520V3

For more information about each of the adapters, see the product guides in the RAID adapters or HBA sections of the Lenovo Press web site:

https://lenovopress.com/servers/options/hba

Internal drive options

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

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

Internal backup units

The SR645 V3 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 57. 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 SR645 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 at the rear (but not both). Slot availability is based on riser selection and drive bays configured. The use of slot 3 and the front slots require that both processors be installed.

Internal (CFF) RAID adapter/HBA: For configurations with 2.5-inch front drive bays, an internal RAID adapter or HBA (CFF, 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.

Topics in this section:

Rear slots

The following figure shows the locations of the rear-accessible slots for each configuration selection. The OCP slot is located below the PCIe slots.

SR645 V3 rear slots
Figure 15. SR645 V3 rear slot configurations

The rear-accessible slots and riser cards are as follows:

  • Riser 1: Slots 1 & 2 (connect to CPU 1)
    • 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 (connects to CPU 2)
    • Slot 3: Low Profile or FHHL, PCIe x16 (only in configuration A and C)

The PCIe slots can be configured as PCIe 5.0 (Gen 5) or PCIe 4.0 (Gen 4) depending on your workload requirements, however slot 2 will always be PCIe 4.0.

The following table lists the ordering information for the rear PCIe slots in the SR645 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.

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 in the table below.

The following configuration requirements must be met when installing GPUs:

  • All GPUs installed must be identical
  • Rear drive bays bays are not supported
  • Flash storage adapters are not supported.
  • Maximum ambient temperature is 30°C
  • Performance fans are required and will be derived by the configurator for configure-to-order builds.
  • When adding GPUs as field upgrades, you will be required to replace all Standard fans with Performance fans. See the Cooling section for ordering information.
  • For details regarding supported combinations of front drive bays, processors, fans, and ambient temperature, see the Thermal Rules page of the User Guide:
    https://pubs.lenovo.com/sr645-v3/thermal_rules#server-models-with-gpus

Cooling

The SR645 V3 server has up to eight 40 mm dual-rotor hot-swap variable-speed fans. Six fans are needed when one processor is installed and eight fans are required when two processors are installed. The server offers N+1 rotor redundancy. The server also has one additional fan integrated in each of the two power supplies.

Depending on the configuration, the server will need either Standard fans (21K RPM) or Performance fans (28K RPM)

Under the following conditions, Standard fans can be used:

  • Processor with TDP ≤ 240W
  • No GPUs
  • Front drive bays ≤ 8x SAS/SATA drives
  • Rear drive bays SAS/SATA, 7mm or 2.5-inch
  • No NVMe drives, front or rear
  • No 256GB 3DS RDIMMs
  • None of the following network adapters:
    • Any 100Gb, 200Gb or 400Gb adapter

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

Systems management

The SR645 V3 contains an integrated service processor, XClarity Controller 2 (XCC), which provides advanced control, monitoring, and alerting functions. The XCC2 is based on the AST2600 baseboard management controller (BMC) using a dual-core ARM Cortex A7 32-bit RISC service processor running at 1.2 GHz.

Topics in this section:

System I/O Board

The SR645 V3 implements a separate System I/O Board that connects to the Processor Board. The location of the System I/O Board is shown in the Components and connectors section. The System I/O Board contains all the connectors visible at the rear of the server as shown in the following figure.

System I/O Board
Figure 19. System I/O Board

The board also has the following components:

  • XClarity Controller 2, implemented using the ASPEED AST2600 baseboard management controller (BMC).
  • Root of Trust (RoT) module - a daughter card that 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.
  • Connector to enable an additional redundant Ethernet connection to the XCC2 controller. The connector is used in conjunction with the ThinkSystem V3 Management NIC Adapter Kit (4XC7A85319). For details, see the Remote management section.
  • Internal USB port - to allow the booting of an operating system from a USB key. The VMware ESXi preloads use this port for example. Preloads are described in the Operating system support section.
  • MicroSD card port to enable the use of a MicroSD card for additional storage for use with the XCC2 controller. XCC2 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 XCC2 controller will have 100MB of available RDOC storage.

Ordering information for the supported USB drive and Micro SD card are listed in the following table.

Light path diagnostics

The server offers light path diagnostics. If an environmental condition exceeds a threshold or if a system component fails, the XCC lights LEDs inside the server to help you diagnose the problem and find the failing part. The server has fault LEDs next to the following components:

  • Each memory DIMM
  • Each drive bay
  • Each power supply

Integrated Diagnostics Panel for 8x 2.5-inch and EDSFF configurations

For configurations with 8x 2.5-inch drive bays or 16x EDSFF drive bays at the front, the server can optionally be configured to have a pull-out Integrated Diagnostics Panel. The following figure shows the configurations with the standard (fixed) operator panel and the optional Integrated Diagnostics Panel.

Operator panel choices for the EDSFF and 8x 2.5-inch drive bay configurations
Figure 21. Operator panel choices for the EDSFF and 8x 2.5-inch drive bay configurations

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

  • Active alerts
  • Status Dashboard
  • System VPD: machine type & mode, serial number, UUID string
  • System firmware levels: UEFI and XCC firmware
  • XCC network information: hostname, MAC address, IP address, DNS addresses
  • Environmental data: Ambient temperature, CPU temperature, AC input voltage, estimated power consumption
  • Active XCC sessions
  • System reset action

The Integrated Diagnostics Panel can be configured as listed in the following table. It is only available configure-to-order (CTO); not available as a field upgrade.

CTO only B8NH ThinkSystem 1U Integrated Diagnostics Panel

Configuration rules for the Pull-out operator panel:

  • Only supported with configurations with 8x 2.5-inch drive bays or with EDSFF drive bays
  • Not available as a field upgrade. The component is CTO or on pre-configured models only

Front VGA and External Diagnostics ports

The VGA port at the rear of the server is included in all models, however the VGA port at the front of the server is optional. The ThinkSystem V2/V3 1U Front VGA Cable Option Kit allows you to upgrade your server by adding a VGA video port to the front of the server (if the server does not already come with a front VGA port). When the front VGA is in use, the rear VGA port is automatically disabled.

The SR645 V3 optionally includes a port to connect an External Diagnostics Handset. To include in a server, ensure the appropriate feature code is included, based on the front drive configuration. Field upgrades to add the External Diagnostics port are not available.

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 SR645 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 SR645 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 82. 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.
