UEFI operating modes

The SR635 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.

UK and EU customers: For compliance with the ERP Lot9 regulation, you should select feature BFYA. For some systems, you may not be able to make a selection, in which case, it will be automatically derived by the configurator.

Table 15. 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 SR635 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 SR635, see the paper "Tuning UEFI Settings for Performance and Energy Efficiency on AMD Processor-Based ThinkSystem Servers", available from https://lenovopress.lenovo.com/lp1267.

* Supported in the SR635 only with an EPYC 7002 processor. Not supported with an EPYC 7003 processor.

The following rules apply when selecting the memory configuration:

  • The 128GB 2933 MHz 3DS RDIMM, 4ZC7A15113, is only supported in the SR635 with an EPYC 7002 processor.
  • The server supports RDIMMs and 3DS RDIMMs
  • Mixing of RDIMMs and 3DS RDIMMs 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.
  • Mixing of 3200 MHz and 2933 MHz DIMMs is supported. Installed memory will operate at the lower speed.
  • Memory mirroring and memory rank sparing are not supported.
  • When a GPU is added as a field upgrade, all empty DIMM slots must have a dummy DIMM blank installed in each DIMM slot, to ensure the optimal air flow. Ordering information is in the following table. For CTO orders, the dummy DIMMs are derived by the configurator.
Table 17. ThinkSystem Dummy DIMM Kit
Part number Description Quantity required
4M27A11810 ThinkSystem Dummy DIMM Package Kit
(contains 24 dummy memory DIMMs)		 1

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.
  • For more details on how to best configure the memory subsystem for performance, refer to the Lenovo Press paper “Balanced Memory Configurations with 2nd Gen and 3rd Gen AMD EPYC Processors” available from
    https://lenovopress.com/lp1268-balanced-memory-configurations-with-amd-epyc-processors

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

PM983 hot-swap support: To support hot-swap of PM983 NVMe drives, the server needs to have UEFI v2.0 (Build ID CFE108O) or later installed.

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.

The 10x NVMe drives at the front makes use of the 10-bay AnyBay backplane (feature B5VS) which requires SAS/SATA cabling and controllers as well as the NVMe cabling. However, if 16x NVMe drive bays are configured (ie all drive bays in the server populated with NVMe drives), then the server can be configured in the DCSC configurator without SAS/SATA cabling and controllers. Note that all 16x NVMe drive bays must be configured (using backplanes B5VS, B5VN and B5VQ); configurations of 10 or 12 or 14x NVMe drive bays will require SAS/SATA cabling and controllers.

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.

SR635 front drive bay configurations
Figure 6. SR635 front drive bay configurations

The backplanes used to provide these drive bays are listed in the following table.

10x NVMe drive support: The server supports 10x 2.5-inch NVMe-only drive bays in the front of the server. Such support makes use of the 10-bay AnyBay backplane (feature B5VS), however the SAS/SATA connectors on the backplane are not connected, and no SAS/SATA cabling or controllers are configured.

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.

Field upgrades

This section describes the available upgrades to the storage subsystem.

Backplane upgrades

The following table lists the option part numbers for the backplane kits that allow you to add additional drive bays as field upgrades. The table also lists what major components are included in each kit.

When adding drive bays, you will also need to add the appropriate storage controller(s). Consult the tables in the Adapter 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.

Use with X40 adapters: These backplane kits in the table below include SAS/SATA cables for use with the onboard SATA controller or with RAID 930, 730, 530 adapters and 430 HBAs (collectively called X30 adapters). If you are adding or upgrading to RAID 940 adapters or 440 HBAs (collectively called X40 adapters), you will need to also order an X40 cable kit. See the Cable kits for 440 HBAs and RAID 940 adapters section for details.

Cable kits for 440 HBAs and RAID 940 adapters

The backplane kits listed in the preceding table include cables for use with the onboard SATA controller or with RAID 930, 730, 530 adapters and 430 HBAs (collectively called X30 adapters). If you wish to use the backplane kits with RAID 940 adapters or 440 HBAs (collectively called X40 adapters), then you will also need to order an additional X40 cable kit to use instead of the cables in the backplane kit.

Unused cables: When adding an X40 adapter, you will order both the backplane kit and the relevant X40 cable kit, however the SAS/SATA data cable(s) in the backplane kit will not be used.

Upgrades from onboard SATA: If you are upgrading a system that currently uses the onboard SATA controller and has all necessary backplanes, simply order the relevant X40 cable kit as listed in the table.

Cable kit for Onboard SATA controller upgrades (X30 adapters only)

If your existing server is configured with drive backplanes that are connected to onboard SATA ports and you wish to upgrade to an X30 RAID adapter or SAS HBA (RAID 930, 730, 530 adapters and 430 HBAs), you will need to order the cable kit listed in the following table along with the adapter(s). The cable kit includes the additional cables you will need to connect the existing backplane to the new X30 adapter. Note that the kit includes the cables needed for all supported combinations of backplanes; this means that some of the cables in the kit will not be used.

For X40 RAID adapters and HBAs, instead order one of the X40 cable kits listed in the Cable kits for 440 HBAs and RAID 940 adapters section.

RAID flash power module (supercap)

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
  • ThinkSystem RAID 940-8i 4GB Flash PCIe Gen4 12Gb Adapter
  • ThinkSystem RAID 940-16i 4GB Flash PCIe Gen4 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.

Part number Description
4XH7A99569 ThinkSystem 2.5" 1x1 HDD Filler by 8 units (contains 8x single drive-bay fillers)

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. The table also includes the cable kit needed for field upgrades.

Field upgrades: When ordering either option part number as a field upgrade, you will also need to order the M.2 Cable Kit which includes the necessary cables to connect the M.2 modules to the server. For CTO orders, the cable kit is not required; the cable and brackets are automatically included in the order.

Configuration notes:

  • Tri-Mode not supported: In the SR635, the Tri-Mode (Trimode) feature of the RAID 940-8i and 940-16i adapters (support for NVMe U.3 drives) is not supported.
  • Field upgrades: If you are adding a RAID adapter to the SR635 as a field upgrade, you will need a Supercap Installation Kit as described in the Field upgrades section. For use of 940 RAID adapters or 440 HBAs, you will also need a cable kit. Take note of the configuration rules in that section.
  • RAID 530-8i firmware: If you plan to use the RAID 530-8i in the SR655, 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.

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 46. 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 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.

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

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
  • Rear drive bays and mid-chassis drive bays are not supported.
  • Flash storage adapters are not supported.
  • 1100W power supplies (or in some configurations, 750W power supplies) are required.
  • If the intrusion switch is installed, then only two GPUs can be installed, in slots 2 and 3. The intrusion switch and a GPU in slot 1 are mutually exclusive.

Additional rules when installing T4 GPUs:

  • With two GPUs installed, processor TDP greater than 200W not supported
    • If ambient temperature is 35°C, then processor TDP greater than 120W not supported
    • If ambient temperature is 30°C, then processor TDP greater than 200W not supported
  • With three GPUs installed, processor TDP greater than 120W not supported
  • The following additional drive backplane rules apply if 3 GPUs are installed (rules do not apply if only 2 GPUs installed):
    • 3.5-inch drive bay backplane (AUW8) is fully supported
    • 8x 2.5-inch drive backplane (B7K3) supported, however 2 drive bays (6, 7) must be empty
    • 6x 2.5-inch SAS/SATA + 4x AnyBay backplane (AUW9) supported, however all AnyBay bays (6, 7, 8, 9) must be empty
    • 10x 2.5-inch AnyBay backplane (B5VS), however 4 bays (6, 7, 8, 9) must be empty
    • Ambient temperature great than 30°C is not supported
    • Processor TDP greater than 120W is not supported

Additional rules when installing any quantity of P620 GPUs:

  • All front drive bay configurations are supported
  • Ambient temperature great than 35°C is not supported
  • Processor TDP greater than 240W is not supported

GPU field upgrades

When ordering GPUs as part of a CTO configuration, the necessary cooling features are automatically selected as part of the order. However when ordering the GPUs as field upgrades, you will need to also order 7 performance fans which will replace the standard fans already installed. 7 part numbers will need to be ordered per server.

Table 57. Performance fan ordering information
Part number Description Quantity required
4F17A14483 ThinkSystem SR635 Performance Fan Module 7

When a GPU is added as a field upgrade, all empty DIMM slots must have a dummy DIMM blank installed in each DIMM slot, to ensure the optimal air flow. Ordering information is in the following table.

Cooling

The SR635 server has seven 40 mm dual-rotor hot-swap variable-speed fans and either 6 or 7 fans are standard depending on the configuration. The fans are dual-rotor counter-rotating units, which means that the fans have two separate propellors, one in front of the other, and that the propellors rotate in opposite directions. The server offers N+1 redundancy. The server also has one additional fan integrated in each of the two power supplies.

Under all of the following conditions, only 6 fans are required:

  • No M.2 Module
  • No internal riser slot
  • No mid drive bays
  • No rear drives
  • No GPUs

For all other configurations, all 7 fans are required.

supported
4F17A12358 B5X1 ThinkSystem SR635 1U Fan Module 7
4F17A14483 B5X0 ThinkSystem SR635 Performance Fan Module 7

Some configurations, such as the use of high-TDP processors, GPUs, flash storage adapters, mid drive or rear drives, or Ethernet/InfiniBand adapters of 100Gb or higher, will require the use of high performance fans which have higher RPMs. For configure-to-order builds, the DCSC configurator will automatically select the required fans. For field upgrades, the option part numbers may include the upgraded components when they are needed, or you may need to order the performance fans separately.

See these sections for details:

Power supplies

The server supports up to two redundant hot-swap power supplies.

The power supply choices are listed in the following table. Both power supplies used in server must be identical.

Lenovo Financial Services

Why wait to obtain the technology you need now? No payments for 90 days and predictable, low monthly payments make it easy to budget for your Lenovo solution.

  • Flexible

    Our in-depth knowledge of the products, services and various market segments allows us to offer greater flexibility in structures, documentation and end of lease options.

  • 100% Solution Financing

    Financing your entire solution including hardware, software, and services, ensures more predictability in your project planning with fixed, manageable payments and low monthly payments.

  • Device as a Service (DaaS)

    Leverage latest technology to advance your business. Customized solutions aligned to your needs. Flexibility to add equipment to support growth. Protect your technology with Lenovo's Premier Support service.

  • 24/7 Asset management

    Manage your financed solutions with electronic access to your lease documents, payment histories, invoices and asset information.

  • Fair Market Value (FMV) and $1 Purchase Option Leases

    Maximize your purchasing power with our lowest cost option. An FMV lease offers lower monthly payments than loans or lease-to-own financing. Think of an FMV lease as a rental. You have the flexibility at the end of the lease term to return the equipment, continue leasing it, or purchase it for the fair market value. In a $1 Out Purchase Option lease, you own the equipment. It is a good option when you are confident you will use the equipment for an extended period beyond the finance term. Both lease types have merits depending on your needs. We can help you determine which option will best meet your technological and budgetary goals.

Ask your Lenovo Financial Services representative about this promotion and how to submit a credit application. For the majority of credit applicants, we have enough information to deliver an instant decision and send a notification within minutes.
