One-processor configurations

The SR645 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:

  • 16 memory DIMMs for a 2TB maximum
  • Slot 1 and Slot 2 are available; Slot 3 is not available

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

Thermal restrictions by processor

In the SR645, processors either use 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.

The use of higher-TDP processors may have restrictions on the use of GPUs, rear drives and network adapters, depending on the front drive backplane use. Specifics are listed in the following table.

4X77A12189 BCZZ ThinkSystem 64GB TruDDR4 Performance+ 3200 MHz (2Rx4 1.2V) RDIMM-A

The following rules apply when selecting the memory configuration:

  • The server supports RDIMMs and 3DS-RDIMMs.
  • Mixing of RDIMMs and 3DS-RDIMMs is not supported.
  • Mixing of Performance+ and non-Performance+ DIMMs is not supported
  • Mixing x4 and x8 DIMMs is supported, but not in the same channel
  • 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 32GB and 64GB). 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 memory DIMMs in quantities of 8 or 16, so that all memory channels are used.
  • Populate memory channels so they all have the same total memory capacity.

The following memory protection technologies are supported:

  • ECC detection/correction
  • SDDC (for x4-based memory DIMMs; look for "x4" in the DIMM description)
  • Patrol/Demand Scrubbing
  • DRAM Address Command Parity with Replay
  • DRAM Uncorrected ECC Error Retry
  • Post Package Repair

Internal storage

The SR645 supports 4x 3.5-inch or 12x 2.5-inch 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 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
  • 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.

In this section:

NVMe drive support

The SR645 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 full x4 connection (4 lanes) to the processor), 10 drives at the front and 2 drives at the rear.
  • In 3.5-inch front drive configurations, two 2.5-inch NVMe drives are supported at the rear of the server.

The specifics of these configurations are covered in the Supported drive bay combinations and Controller selections sections.

In addition, the SR645 supports two 7mm NVMe drives for use as boot drives. These two drives are connected via separate RAID controller connected to a single PCIe 3.0 x2 host interface. See the 7mm drives section for details.

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. Such support provides greater flexibility and allows the use of the low-latency and high-IOPS benefits of NVMe drives connected to a standard RAID adapter. Tri-Mode is supported with U.3 NVMe drives in either 2.5-inch and 3.5-inch form factor.

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:

  • 3.5-inch drive bays
    • No backplane and no drives (supports field upgrades)
    • 4x 3.5-inch SAS/SATA
    • 4x 3.5-inch AnyBay
  • 2.5-inch drive bays
    • No backplane and no drives (supports field upgrades)
    • 4x 2.5-inch hot-swap SAS/SATA
    • 8x 2.5-inch hot-swap SAS/SATA
    • 6x 2.5-inch hot-swap SAS/SATA + 4x hot-swap AnyBay
    • 6x 2.5-inch hot-swap SAS/SATA + 4x hot-swap NVMe
    • 6x 2.5-inch hot-swap SAS/SATA + 2x hot-swap AnyBay + 2x hot-swap NVMe
    • 10x 2.5-inch hot-swap SAS/SATA
    • 10x 2.5-inch hot-swap AnyBay
    • 10x 2.5-inch hot-swap NVMe
    • 8x 2.5-inch hot-swap NVMe + 2x hot-swap NVMe

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

Tip: The 8x 2.5-inch SAS/SATA drive configuration can be configured with or without an Integrated Diagnostics Panel with pull-out LCD display. See the Local management section for details.

Common backplanes: Some of the backplanes listed in the above table are shared:

  • Feature codes BHU8, B8MX, BCQN and BCQP all use a backplane with 6x SAS/SATA bays and 4x AnyBay bays. The difference is which connectors on the backplane are cabled for each of the four AnyBay bays - NVMe or SAS/SATA or both. These all use backplane SBB7A06903.
  • Feature codes BB3T, BCQQ, and BCQR all use the 10x AnyBay backplane. The difference is how the bays are cabled - NVMe only or both NVMe and SAS/SATA. These all use backplane SBB7A20714. 

Rear drive bays

The SR645 supports hot-swap drives installed at the rear of the server chassis. Supported configurations are as follows:

  • 2x 2.5-inch hot-swap SAS/SATA drive bays
  • 2x 2.5-inch hot-swap NVMe drive bays
  • 2x 7mm SAS/SATA drive bays
  • 2x 7mm NVMe drive bays

Field upgrades

The SR645 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.

Tip: There is no upgrade path to add drive bays if the SR645 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 Controller selections 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.

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:

  • ThinkSystem RAID 930-8i 2GB Flash PCIe 12Gb Adapter
  • ThinkSystem RAID 930-16i 4GB Flash PCIe 12Gb Adapter

* 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 7mm drives section for details.
  • RAID 530-8i firmware: If you plan to use the RAID 530-8i in the server, it must have firmware 50.3.0-1032 or later applied before it can be used in the server. If the adapter you plan to use has older firmware (for example, you are using an adapter you previously purchased), it must first be upgrade by installing it in another server and upgrading the firmware there. For more information, see Support tip HT509177.

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. Such support provides greater flexibility and allows the use of the low-latency and high-IOPS benefits of NVMe drives connected to a standard RAID adapter. Tri-Mode is supported with U.3 NVMe drives in either 2.5-inch and 3.5-inch form factor.

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
  • Supports HDDs and SSDs; can be mixed

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

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:

Table 48. USB memory key
Part number Feature Description
4X77A08621 B8NV ThinkSystem 32GB USB 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

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, CD-RW, CD-R, CD-ROM.

I/O expansion

The server supports a total of up to 3 PCIe 4.0 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.

  • Slot 1: PCIe 4.0 x16 LP (CPU 1)
  • Slot 2: PCIe 4.0 x16 LP or FHHL (CPU 1)
  • Slot 3: PCIe 4.0 x16 LP (CPU 2)

Slots 1 and 2 are also available as PCIe 3.0 adapter slots, using a lower-cost PCIe 3.0 riser, if desired.

Tip: 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 4.0 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.

SR645 slots
Figure 12. SR645 slot configurations

The slots and riser cards are as follows:

  • Riser 1: Slots 1 & 2
    • Slot 1: Low Profile, PCIe 4.0 x16
    • Slot 2: Low Profile or FHHL, PCIe 4.0 x16 (not available in configuration C in the above figure)
  • Riser 2: Slot 3 (requires CPU 2)
    • Slot 3: Low Profile, PCIe 4.0 x16 (only available in configuration A)

The riser cards and slot brackets used to provide the above slot combinations in configure-to-order (CTO) configurations are listed in the following table.

Tip: It is also possible to not have any slot selections, 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.

Use of the Mellanox HDR PCIe Aux Kit: The HDR Aux Kit (4C57A14179) enables a Socket Direct connection which allows the HDR adapter (4C57A15326) to have direct access to each of the two processors. Such a configuration ensures extremely low latency and CPU utilization in addition to higher network throughput. Socket Direct also maximizes AI and ML application performance, as it enables native GPU-Direct Technologies.

The following thermal requirement apply to ConnectX-6 adapters:

  • The high performance cooling fans must be installed. See the Cooling section for details.
  • The use of high-TDP processors may not be supported, depending on the configuration. See the Thermal restrictions by processor section for details.
  • The maximum ambient temperature supported is 35°C. If the adapter uses 100Gb Active Optical Cables (AOCs), the maximum ambient temperature supported is reduced to 30°C.

Configuration rules

The RAID 930-8e uses a flash power module (supercap), which can be installed in one of the locations as shown in the following figure.

Locations of supercaps
Figure 13. Potential locations of all supercaps in the SR645 (2.5-inch drive configuration and standard heatsinks)

The number of 930-8e RAID adapters supported is based on how many supercaps can be installed in the server. The number and location of the supercaps is determined based on the front drive configuration used and which processor heatsinks are installed, as listed in the following table.

Note: If an internal 930i RAID adapter with flash power modules is installed, the maximum number of 930-8e adapters supported is reduced by 1.
