One-processor configurations

The SR645 V3 can be used with only one processor installed. Most core functions of the server (including the XClarity Controller) are connected to processor 1 as shown in the System architecture section.

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

  • 12 memory DIMMs
  • Slot 1 and Slot 2 are available; Slot 3 is not available

Drive support and controller support is as listed in the Storage configurations section - see the CPUs column in the tables for the configurations that support 1 processor.

Thermal requirements by processor

In the SR645 V3, most processors use a performance heatsink, which include two satellite heatsinks that connect to the main heatsink via liquid filled copper tubes. However, for processors with a TDP of 320W or higher, a new closed-loop liquid-cooled design is used to remove heat from the processors.

The use of processors with 320W or higher TDP has the following restrictions:

  • The closed water-loop heatsink is required (feature BS34) - see the figure below
  • Two processors are required
  • 3.5-inch and EDSFF front drive bays are not supported
  • The following 2.5-inch drive configurations are not supported:
    • 10x 2.5-inch AnyBay with Gen 4 or Gen 5 cabling
    • 10x 2.5-inch NVMe with Gen 5 cabling
  • The following components are not supported:
    • Rear drives (2.5-inch, 3.5-inch, 7mm)
    • GPUs
    • M.2 drives
    • Any internal RAID/HBAs (CFF form factor)

The following figure shows the placement of the components in the closed-loop system. Cold plates are mounted on top of each processor and these are connected via copper tubes to a radiator that is placed in front of the system fans. The liquid is actively pumped through the pipes in a closed loop to remove the heat from the processors.

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

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 7. 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.

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.

Optimized DIMMs (also known as 9x4 or EC4 RDIMMs) are a new lower-cost DDR5 memory option supported in the SR645 V3. Optimized 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 Optimized 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 Optimized RDIMMs do not support SDDC. Note, however, that all DDR5 DIMMs, including Optimized 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 server supports three types of DIMMs: Optimized (9x4) RDIMMs, RDIMMs, and 3DS RDIMMs; UDIMMs and LRDIMMs are not supported
  • Mixing of DIMM types is not supported (Optimized DIMMs with RDIMMs, Optimized DIMMs with 3DS RDIMMs, RDIMMs with 3DS RDIMMs)
  • Mixing of 128GB 3DS RDIMMs and 256GB 3DS RDIMMs 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.
  • 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.

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 Optimized 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. 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. 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 - 4 drive bays
    • 4x SAS/SATA
    • 4x NVMe (PCIe Gen4)
  • 2.5-inch hot-swap drive bays - 8 drive bays

    • 10x AnyBay (PCIe Gen4 or Gen5)
    • 10x NVMe (PCIe Gen4)
  • 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.

The use of rear 2.5-inch drive bays has the following configuration rules:

  • With 2.5-inch rear drive bays, only slot 1 is available. Slot 2 and 3 are not available
  • GPUs are not supported

The use of the 7mm rear drive bays has the following configuration rules:

  • The 7mm drive bays support either SATA drives or NVMe drives but not both. You specify SATA or NVMe in the configurator using feature codes BTTV (SATA) or BTTW (NVMe).
  • 7mm rear drive bays occupy slot 3; slots 1 and 2 are available and slot 2 is a low profile slot. Slot 3 is not available.
  • If RAID support is not required, the 7mm drives connect to an onboard port; No additional adapter is required
  • If RAID support is required, select feature code BS7A in the configurator to enable RAID
  • The support of RAID-1 with the 7mm drives requires an additional RAID adapter that is installed in PCIe slot 2:
    • RAID support for 7mm SATA drives requires a RAID 5350-8i adapter (feature BT7N)
    • RAID support for 7mm NVMe drives requires a RAID 540-8i adapter operating in Tri-Mode (feature BT7P)
  • The RAID adapter used for 7mm drive support cannot be configured for use with other drive bays (not even with M.2)
  • M.2 RAID and 7mm RAID are mutually exclusive: they are not supported together in the same configuration
  • GPUs are not supported

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 Information Center:
https://thinksystem.lenovofiles.com/help/topic/7D9C/system_options.html

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.

For field upgrades to add 7mm drive bays, order one of the part numbers listed in the following table.

RAID support: The 7mm Enablement Kit part numbers below do not include the RAID adapter needed for 7mm RAID support. You will also need to order either the 5350-8i for SATA RAID support or 540-8i for NVMe RAID support. In addition, the 540-8i, once installed, will need to be configured to operate in Tri-mode to enable NVMe RAID.

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

There are two possible locations for supercaps, depending on the front drive bays (2.5-inch or 3.5-inch) and the size of the processor heatsinks. Details are summarized in the following table. Location references are shown in the figure below.

M.2 drives

The SR645 V3 supports one or two M.2 form-factor SATA or NVMe drives for use as an operating system boot solution or as additional storage.

The M.2 drives install into an M.2 module which is mounted horizontally in the server in front of the fans as shown in the Internal view of the server. In configurations with 2.5-inch front drive bays, the M.2 module is position between the drive bays and the fans. In configurations with 3.5-inch front drive bays, the M.2 module is mounted on top of the front drive bays.

The supported M.2 modules are listed in the following table. For field upgrades see the M.2 field upgrades section below.

* 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 3 supercaps depending on the server configuration as described in the RAID flash power module (supercap) support section. The number of supercaps supported also determines the maximum number of RAID adapters with flash that can be installed in the server.
  • Field upgrades: If you are adding a RAID adapter with supercap to the server as a field upgrade, you may need a supercap holder as described in the RAID flash power module (supercap) support section.
  • 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 2Q/2023 (23A).

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 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/raid
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.

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 41. 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 3 PCIe slots, all with rear access, plus a dedicated OCP 3.0 SFF slot for networking. Slot availability is based on riser selection. The use of slot 3 requires that both processors be installed. The SR645 V3 also supports front-accessible PCIe slots (planned support 2Q/2023).

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.

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.

Front PCIe slots: Support for front PCIe slots (config F) is planned for 2Q/2023.

SR645 V3 slots
Figure 12. SR645 V3 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 front-accessible slots and riser cards are as follows (planned for 2Q/2023):

  • Slot 4: Low Profile, PCIe 4.0 x16 (connects to CPU 2)
  • Slot 5: FHHL, PCIe 4.0 x16 (connects to CPU 2)

The following table lists the ordering information for the 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 as listed in the Field upgrades table.

  • 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.

Cooling

The SR645 V3 server has up to eight 40 mm dual-rotor hot-swap fans. Six fans are needed when one processor is installed and eight fans are required when two processors are installed. The server offers N+2 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 (24K RPM)

Under the following conditions, Standard fans can be used:

  • Processor with 120W TDP, and the following requirements:
    • No GPUs
    • No rear drives (2.5-inch or 7mm)
  • Processor TDP ≤ 170W, and the following requirements:
    • No GPUs
    • No rear drives (2.5-inch or 7mm)
    • 4x 2.5-inch front drive backplane or 8x 2.5-inch front drive backplane

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. 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.

ThinkSystem 1100W -48V DC v2 Power Supply
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.

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 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

Standby mode: When Standby mode (also known as zero-output mode) is configured in System Setup 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. Standby mode can be enabled or disabled in System Setup (F1 at boot time) via System Settings > Power > Zero Output and select either Enable or Disable. 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 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 feature code to enable secure boot in the factory, or to leave it disabled.

Table 63. Secure Boot options
Part number Feature code Description Purpose
CTO only BPKQ TPM 2.0 with security 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.
