The following rules apply when selecting the memory configuration:

  • The server currently supports only RDIMMs.
  • Mixing of DIMM vendor is supported, but not in the same channel (see the table above)
  • 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.
  • Mixing of 3200 MHz and 2933 MHz DIMMs is supported, but not in the same channel
  • 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 SR635 supports 4x 3.5-inch or 16x 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.

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 three drive bay zones are as follows:

  • Front: 4x 3.5-inch hot-swap bays or up to 10x 2.5-inch hot-swap bays
  • Mid (internal): 4x 2.5-inch hot-swap bays
  • Rear: up to 2x 2.5-inch hot-swap bays

The server also supports one or two M.2 drives, installed in an M.2 adapter.

In this section:

NVMe drive support

No hot-swap support: NVMe drives currently do not support hot-swap functionality. An update to UEFI firmware to fix this restriction is planned for 4Q/2019.

The SR635 supports NVMe drives to maximize storage performance. The server supports up to 16 NVMe drives without oversubscription (that is, each x4 drive has a full x4 connection (4 lanes) to the processor):

  • 10x NVMe drives in the front bays
  • 4x NVMe drives in the mid bays
  • 2x NVMe drives in the rear bays

The specifics of these configurations plus other NVMe-rich configurations are covered in the Supported drive bay combinations and  Adapters selections sections.

15mm NVMe drives: 15mm NVMe SSDs are not supported in the mid or rear drive bays due to thermal requirements. Only 7mm NVMe drives are supported in those zones.

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

These configurations are shown in the following figure.

The use of drive bays in the mid-chassis area has the following configuration rules:

  • Only NVMe drives are supported in the mid chassis area. SAS and SATA drives are not supported.
  • The mid drive cage is only supported in conjunction with the 10x 2.5-inch AnyBay backplane (feature AUW9) or the 4x 3.5-inch SAS/SATA backplane (feature AUW8) for the front drives. The use of other front-drive backplanes with the mid cage is not supported.
  • The mid drive cage occupies the same physical space as the M.2 module, internal PCIe slot (slot 4) and two of the three holders for RAID power module (supercaps). As a result, the M.2 module, slot 4 and two supercaps cannot be installed.

Rear drive bays

The SR635 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

The configurations are shown in the following figure.

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 730-8i 2GB Flash PCIe 12Gb Adapter
  • ThinkSystem RAID 930-8i 2GB Flash PCIe 12Gb Adapter
  • ThinkSystem RAID 930-16i 4GB Flash PCIe 12Gb Adapter

There are three possible locations for supercaps, as shown in the following figure.

Location of all three supercaps
Figure 9. Location of all three supercaps in the SR635

The following configuration rules apply to the use of supercaps:

  • Locations 1 and 2 are not available if the mid-chassis drive cage is installed
  • Location 3 is only available with 2.5-inch front drive bays. It is not available if 3.5-inch front drives are used

When adding a RAID adapter and supercap as a field upgrade, order the supercap installation kit list listed in the following table.

Table 23. RAID Flash Power Module installation kit

4XH7A09847 B72A

ThinkSystem SR635/SR655 Supercap Installation Kit

  • 1x Bracket to hold two supercaps in their holders
  • 3x Supercap holders

The following figure shows the use of the components of the option kit to install 1 or 2 supercaps. The third supercap is installed in location 3 in front of the cooling fans and behind the front operator panel as shown in the preceding figure (2.5-inch chassis only; not available with 3.5-inch front drives).

Supercap Installation Kit
Figure 10. Supercap Installation Kit (locations 1 and 2)

M.2 drives

The server supports one or two M.2 form-factor SATA 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 adjacent to the internal storage controller slot as shown in the Components and connectors section.

M.2 restriction: The M.2 Module cannot be used in certain drive bay combinations:

  • When 12 SATA or AnyBay drive bays are configured (10 front, 2 rear) and the SATA drives are connected to the onboard SATA controller (onboard SATA and M.2 use the same connector)
  • When 4 mid-chassis drive bays are configured (M.2 occupies the same space)

See Adapter selections for the specific combinations where the M.2 Module is not supported.

There are two M.2 modules supported, as listed in the following table.

I/O expansion

The server supports a total of up to 4 PCIe 4.0 slots (3 with rear access, 1 internal for a RAID adapter or HBA) plus a dedicated OCP 3.0 SFF slot for networking. Slot availability is based on riser selection.

  • Slot 1: PCIe 4.0 x16 LP or FHHL
  • Slot 2: PCIe 4.0 x16 LP (not present if slot 1 is FHHL or rear drive bays are present)
  • Slot 3: PCIe 4.0 x16 LP (not present if rear drive bays are present)
  • Slot 4: PCIe 4.0 x8 LP (internal slot; physically a x16 slot)

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.

SR635 slots
Figure 11. SR635 slots

The slots and riser cards are as follows:

  • Riser 1: Slot 1 (PCIe x16)
    • Slot 1: Low Profile or FHHL, PCIe 4.0 x16 slot
  • Riser 2: Slots 2 & 3 (each PCIe x16)
    • Slot 2: Low Profile, PCIe 4.0 x16 (only available in 3x LP slot configuration)
    • Slot 3: Low Profile, PCIe 4.0 x16 (not available in configurations with rear drive bays)
  • Internal Riser: Slot 4 (PCIe x8)
    • Low Profile PCIe 4.0 x8 slot for internal drive controller (physically a x16 slot)

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.
