UEFI operating modes

The SR655 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 16. 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 SR655 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 SR655, 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 SR655 uses Lenovo TruDDR4 memory operating at up to 3200 MHz. The processors have 8 memory channels and support 2 DIMMs per channel, for a total of 16 DIMMs. The server supports up to 2TB of memory using 16x 128 GB 3DS RDIMMs.

The server supports these memory DIMMs:

  • 2933 MHz DIMMs, that operate at 2933 MHz both at 1 DIMM per channel and 2 DIMMs per channel
  • 3200 MHz DIMMs, that operate at 3200 MHz at 1 DIMM per channel, and at 2933 MHz at 2 DIMMs per channel

Note that if the processor selected has a memory bus speed of 2666 MHz, then all DIMMs will operate at 2666 MHz, even if the DIMMs are rated for a higher speed MHz.

The following table lists the memory options that are available for the server.

Lenovo TruDDR4 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.

* Supported in the SR655 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 SR655 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 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 18. 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 SR655 supports up to 20x 3.5-inch or 32x 2.5-inch drive bays, depending on the selected chassis and backplane configuration. Drives can be all SAS, all SATA, or all NVMe, or combinations of all three (not in the same RAID array, if configured). 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 zones are as follows:

  • Front: up to 12x 3.5-inch or 24x 2.5-inch, hot-swap bays
  • Mid (internal): up to 4x 3.5-inch or 8x 2.5-inch, hot-swap bays
  • Rear: up to 4x 3.5-inch or 4x 2.5-inch hot-swap bays

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

    • Slots 7 and 8 are not available, as described in the I/O expansion section
    • The intrusion switch may be support via Special Bid.
  • The use of NVMe drives in rear bays requires the use of a PCIe switch

Supported drive bay combinations

This section describes the various combinations of 3.5-inch and 2.5-inch drives that the server supports. The drive bay combinations are grouped based on the drive type at the front of the server, 3.5-inch or 2.5-inch.

3.5-inch drive bay chassis

The following table shows the supported combinations when the server is configured with a 3.5-inch chassis (where the front drive bays are 3.5-inch). In this configuration:

  • When the front bays are 3.5-inch bays, the mid bays are also 3.5-inch bays, however the rear zone can be either 2.5-inch SAS/SATA or 3.5-inch SAS/SATA
  • NVMe is only supported in the front bays, using the AnyBay backplane (which offers 4x NVMe-capable drive bays)

The choice of storage controller for each configuration is listed in the Adapter selections section.

2.5-inch drive bay chassis

The server has 36 drive bays in total, however up to 32 drives are supported in a configuration.

The following table shows the supported combinations when the server is configured with a 2.5-inch chassis (where the front drive bays are 2.5-inch). In this configuration:

  • With the 2.5-inch chassis, all drive bays are 2.5-inch bays. No 3.5-inch drives are supported with the 2.5-inch chassis.
  • Mid bays and Rear bays cannot be used concurrently

The choice of storage controller for each configuration is listed in the Adapter selections section.

Adapter selections

The following tables lists the supported drive bay combinations plus the list of supported controller combinations supported by each of those drive bay combinations. Information about the controllers can be found in the Controllers for internal storage section.

General rules for adapters:

  • The RAID 730-8i 1G cannot be used for connection to the rear drive bays
  • Only the RAID 530-8i or the 430-8i HBA can be selected when a separate controller is needed for the rear drive bays
  • The RAID 730-8i 2G cannot be used in the same server as the RAID 730-8i-1G or RAID 930-8i
  • The M.2 Adapter is not supported in configurations of 16 or more 2.5-inch NVMe drives in the front bays
  • For performance reasons, select the 1610-4P NVMe switch adapter instead of the 810-4P NVMe switch adapter, when available

Field upgrades

This section lists the available field upgrade option part numbers for storage upgrades.

Backplane kits

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.

Tip: 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.

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.

Configuration rules:

  • When the onboard SATA controller is used in conjunction with M.2 then at most 12 SATA drives can be configured
  • M.2 is not supported in configurations of 16 or more 2.5-inch NVMe drives in the front bays.
  • Performance fans are required for enhanced cooling. See the Cooling section for ordering information. In CTO orders, the performance fans will be automatically derived in the order.
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. For field upgrades, you will also need to order the performance fans if they are not already installed in your server. See the Cooling section for ordering information.

https://lenovopress.com/lp1288#sr655-support=SR655

Configuration notes:

  • Mixing of adapter families not supported: It is not supported to have a configuration with a mix of X30 and X40 adapter families. For example, you cannot build a configuration with a 930 RAID adapter and 940 RAID adapter.
  • Tri-Mode not supported: In the SR655, the Tri-Mode (Trimode) feature of the RAID 940-8i and 940-16i adapters (support for NVMe U.3 drives) is not supported.
  • Gen 3 NVMe Switch Adapters and Gen 4 NVMe drives: The 810-4P and 1610-4P NVMe Switch Adapters operate at PCIe 3.0 speeds. When PCIe 4.0 NVMe drives are attached to an NVMe Switch Adapter, the drives will only operate at PCIe 3.0 speeds.
  • M.2 and onboard SATA: If you are configuring M.2 and onboard SATA, then at most 12 SATA drives can be connected.
  • Field upgrades: If you are adding a RAID adapter to the SR655 as a field upgrade, you may need a Supercap Installation Kit as described in the Field upgrades 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 49. 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 9 PCIe 4.0 slots (8 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 length is dependent on the use of a mid-chassis drive cage: If the mid drive cage is present then slots are half-length; if the mid drive cage is not present, then slots are full-length.

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.

SR655 slots
Figure 10. SR655 slots

The slots and riser cards are as follows:

  • Riser 1: Slots 1, 2 and 3 - all FHHL or FHFL (16 or 32 lanes)
    • Option 1*: x16, x8, x8 (all physically x16 slots)
    • Option 2*: x16, x16, NC (slot 3 not connected)
    • Option 3: NC, NC, x16 (1U riser; slot 1 and slot 2 not connected)
    • Option 4: x16, NC, NC (slot 2 and slot 3 not connected)
  • Riser 2: Slots 4, 5, and 6 - slot size varies (32 lanes)
    • Option 1: x16, x8, x8 (all physically x16 slots)
    • Option 2: x16, x16, NC (slot 6 not connected)
    • Option 3: NC, NC, x16 (1U riser; slot 4 and slot 5 not connected)
  • Riser 3: Slots 7 and 8 - both FHHL or FHFL (16 or 32 lanes)
    • Option 1*: x8, x8 (both physically x16 slots)
    • Option 2*: x16, x16
  • Slot 9: Internal PCIe 4.0 x8 low-profile slot for internal drive controller (physically a x16 slot)*

* The use of 32 lanes with Riser 1 or the use of Riser 3 or Slot 9 imposes restrictions on the use of the onboard SATA controller or the use of the M.2 Module or both. See the Riser restrictions table below for details.

The riser cards used to provide the above slot combinations are listed in the following table.

As described in this section, the use of some risers results in limitations on the use of NVMe drives, the onboard SATA controller, and M.2 drives. This is due to the dual use of some of the PCIe slimline connectors on the system board - use with riser cards and use with these other functions. The following table summarizes the restrictions.

Tip: The drive bay restrictions in the table refer to the front drive bays.

Network adapters

The server has a dedicated OCP 3.0 SFF slot with PCIe 4.0 x16 host interface. See Figure 3 for the location of the OCP slot.

The following table lists the supported OCP adapters. One port can optionally be shared with the ASPEED management processor for Wake-on-LAN and NC-SI support. Only 1 OCP card can be installed in the server.

280W processor support: There are some restrictions regarding the use of some OCP adapters with a 280W processor installed due to thermal restrictions. See the Operating environment section for details.

For a comparison of the functions of the supported storage adapters, see the ThinkSystem RAID Adapter and HBA Reference:
https://lenovopress.com/lp1288#sr655-support=SR655&internal-or-external-ports=External

Configuration rules

The following configuration rules apply to the use of the RAID 930-8e and RAID 940-8e adapters and the flash power module (supercaps) that each adapter requires:

  • If the 3.5-inch mid-chassis drive cage is configured, then the maximum number of flash power modules (and therefore the maximum number of 930/940-8e adapters) is 2
  • If one or more GPUs are installed, then the maximum number of flash power modules and 930/940-8e adapters is 3.
  • If any internal RAID adapters with flash power modules are installed, the maximum number of 930/940-8e adapters supported is further reduced by that number.

Mixing storage adapter families: The following HBA/RAID adapter combinations are supported:

  • X30 external adapters with other X30 adapters (internal or external)
  • X40 external adapters with other X40 adapters (internal or external)
  • X40 external adapters with X350 internal adapters

The following HBA/RAID adapter combinations are not supported:

  • X30 adapters (internal or external) with X40 adapters (internal or external)
  • X30 adapters (internal or external) with X350 internal adapters

The following figure shows the slots where double-wide (top image) and single-wide (bottom) are installed.

SR655 slots used for GPUs
Figure 11. Slots used for GPUs

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
  • Double-wide GPUs are installed in the top slots of each riser (see I/O expansion for the location of the risers and slots).The adjacent slots are not available for use.
  • For double-wide GPUs and the T4 GPU, the following front drive bay restrictions apply:
    • Maximum of 8x 3.5-inch front drive bays supported (12 bays not supported)
    • Maximum of 16x 2.5-inch front drive bays supported (24 bays not supported)
  • Rear drive bays and mid-chassis drive bays are not supported.
  • Flash storage adapters are not supported.
  • 1600W power supplies (or in some configurations, 1100W power supplies) are required.
  • Processor TDP and ambient temperature limitations are listed in the following table.
Table 61. Processor and thermal requirements for GPUs

6x T4 GPUs 8x 3.5-inch SAS/SATA 200W 35°C

GPU field upgrades

A cooling kit, DIMM fillers and auxiliary power cable kits may be required for 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 the necessary thermal kit. One part number is needed per server.

  • 4H47A38664 is for NVIDIA T4 upgrades
  • 4H47A38663 is for V100/V100S GPU upgrades

NVIDIA P620 GPUs: A thermal kit is not required when installing NVIDIA Quadro P620 GPUs.

Cooling

The SR655 server has six 60 mm single-rotor hot-swap variable-speed fans and either 5 or 6 fans are standard depending on the configuration. The server offers N+1 redundancy, meaning that one fan can fail and the server still operates normally. The server also has one additional fan integrated in each of the two power supplies.

Under all of the following conditions, only 5 fans are required:

  • No M.2 Module
  • No internal riser slot
  • No mid drive bays
  • No GPUs
  • No flash storage adapter
  • No Riser 3

For all other configurations, all 6 fans are required. For fan requirements for OCP adapters, see the table in the Network adapters section

The dimensions of the security bezel are:

  • Width: 437 mm (17.2 in.)
  • Height: 87 mm (3.4 in.)
  • Width: 23 mm (0.9 in.)

The following table lists the security options for the SR655.

Intrusion switch support: The intrusion switch is mounted on the Riser 2 cage. As a result, the intrusion switch requires a 2U riser in the Riser 2 position (either riser B5VU or B5VY). The intrusion switch is not supported if the server has 3.5-inch rear drive bays configured. The use of the intrusion switch with 2.5-inch rear drive bays requires a special bid (CORE) configuration.

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.
