The following figure shows the architectural block diagram of the SR670, showing the major components and their connections.

Figure 5. SR670 system architectural block diagram (four x16 GPU slots)

The following table lists the standard specifications.

The SR670 server is shipped with the following items:

• Documentation flyer
• Power cords (model and region dependent)

ThinkSystem SR670 models can be configured by using the Lenovo Data Center Solution Configurator (DCSC).

Preconfigured server models may also be available for the SR670, however these are region-specific; that is, each region may define their own server models, and not all server models are available in every region.

The following table lists the base CTO models of the ThinkSystem SR670 server.

Models of the SR670 are defined based on whether the server has 4x PCIe x16 slots (suitable for double-wide GPUs) or 8x PCIe x8 slots. See the System architecture section for the block diagram for these two configurations and the I/O expansion options section for the layout of these slots.

For model configurations, the feature codes for these chassis bases are as listed in the following table. There is no functional difference between the v2 and non-v2 variants of the base feature codes.

The following tables list the available models, grouped by region.

• Models for Australia and New Zealand
• Models for South East Asian countries (ASEAN)
• Models for Hong Kong, Taiwan, Korea (HTK)
• Models for Japan

Refer to the Specifications section for information about standard features of the server.

The SR670 supports two processors in the second-generation Intel Xeon Processor Scalable Family. Both processors must be installed.

The server supports the second-generation processor options that are listed in the following table.

Topics in this section:

• Memory capacity of processors
• Processor features
• UEFI operating modes

All supported processors have the following characteristics:

• 14 nm process technology
• Six DDR4 memory channels
• 48 PCIe 3.0 I/O lanes
• 1 MB L2 cache
• 1.375 MB L3 cache or more per core
• Intel Hyper-Threading Technology
• Intel Turbo Boost Technology 2.0
• Intel Advanced Vector Extensions 512 (AVX-512)
• Intel Ultra Path Interconnect (UPI) links at 10.4 GT/s (replaces QPI)

Memory capacity of processors

Second-generation Xeon Scalable processors are limited to the amount of memory they can address, as follows:

• Processors with an L suffix (eg 8280L): Up to 4.5 TB per processor
• Processors with an M suffix (eg 8280M): Up to 2 TB per processor
• All other processors: Up to 1 TB per processor

The calculation is based on each processor individually, not the total memory installed in the server. For example, a configuration using 24x 32GB DIMMs per server is 12x 32 GB per processor, which is 384 GB per processor. This means that neither an M nor an L processor is required.

Processor features

The following table compares the features of the supported second-generation Intel Xeon processors.

* L3 cache is 1.375 MB per core or larger. Processors with a larger L3 cache per core are marked with an *
** The Intel Xeon Gold 5218 and 5218B processors have similar specifications; however, they use different silicon designs and cannot be mixed in the same system.

The following table lists the feature codes that allow you to specify the mode you wish to preset in the factory for CTO orders.

The preset modes for the SR670 are as follows:

• Maximum Performance Mode (feature BFYB): Achieves maximum performance but with higher power consumption and lower energy efficiency.
• Minimal Power Mode (feature BFYC): Minimize the absolute power consumption of the system.
• Efficiency Favoring Power Savings Mode (feature BFYD): Maximize the performance/watt efficiency with a bias towards power savings. This is the favored mode for SPECpower benchmark testing, for example.
• Efficiency Favoring Performance Mode (feature BFYE): Maximize the performance/watt efficiency with a bias towards performance. This is the favored mode for Energy Star certification, for example.

For details about these preset modes, and all other performance and power efficiency UEFI settings offered in the SR670, see the paper "Tuning UEFI Settings for Performance and Energy Efficiency on Intel Xeon Scalable Processor-Based ThinkSystem Servers", available from https://lenovopress.lenovo.com/lp1477.

The SR670 with second-generation Intel Xeon Scalable processors uses Lenovo TruDDR4 memory operating at up to 2933 MHz. The server supports 8, 12, 16 or 24 DIMMs with the two processors installed. Each processor has six memory channels with two DIMMs per channel. The server supports a total of 1.5 TB of system memory (24x 64 GB RDIMMs).

With second-generation processors, the server supports these memory DIMMs:

• 2933 MHz DIMMs, that operate at 2933 MHz at 1 DIMM per channel, and at 2666 MHz at 2 DIMMs per channel
• 2933 MHz Performance+ DIMMs, that operate at 2933 MHz both at 1 DIMM per channel and 2 DIMMs per channel

The following table lists the memory options supported by the SR670 with second-generation processors.

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. From a service and support standpoint, Lenovo TruDDR4 memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.

The following rules apply when selecting the memory configuration:

• The server architecturally supports RDIMMs, LRDIMMs and 3DS RDIMMs. UDIMMs are not supported.
• The SR670 server only supports four memory configurations:
  • 8 DIMMs, which are installed in DIMM slots 3, 5, 8, 10, 15, 17, 20, and 22.
  • 12 DIMMs, which are installed in DIMM slots 1, 3, 5, 8, 10, 12, 13, 15, 17, 20, 22, and 24.
  • 16 DIMMs, which are installed in DIMM slots 3, 4, 5, 6, 7, 8, 9, 10, 15, 16, 17, 18, 19, 20, 21, and 22
  • 24 DIMMs, installed in all slots.
• All DIMMs to be installed must be the same type and capacity.
• If the processor selected has a memory bus speed of less than 2933 MHz (eg 2400 MHz or 2666 MHz - see Processor features), then all DIMMs will operate at that lower speed, even though the DIMMs are rated for 2933 MHz.
• 2666 MHz memory options that are supported with the SR670 using second-generation Xeon processors
• Intel Optane DC Persistent Memory is not supported by the SR670

The following memory protection technologies are supported:

• ECC
• SDDC (for x4-based memory DIMMs; look for "x4" in the DIMM description)
• ADDDC (for x4-based memory DIMMs)
• Memory mirroring
• Memory rank sparing

If memory channel mirroring is used, then DIMMs must be installed in pairs or sets of three (minimum of one pair or set of three per processor), and all DIMMs in the pair or set of three must be identical in type and size. 50% of the installed capacity is available to the operating system.

If memory rank sparing is used, then a minimum of two single-rank or dual-rank DIMMs must be installed per populated channel (the DIMMs do not need to be identical). In rank sparing mode, one rank of a DIMM in each populated channel is reserved as spare memory. The largest rank in the channel will be automatically selected as the spare rank. The amount of memory available to the operating system depends on the number, capacity and rank counts of the DIMMs installed.

The server support 8x 2.5-inch drives. Currently, only SATA HDDs and SSDs are supported. You can mix drives in the same server, but not in the same array. Drives are all installed from the rear of the server. The server also supports one or two M.2 drives, installed in an M.2 adapter.

In this section:

• Backplane and drive bays
• M.2 drives

Backplane and drive bays

The SR670 offers eight 2.5-inch hot-swap drive bays, located at the rear of the server. All eight drive bays are connected to a single backplane. The backplane supports SAS and SATA drives. SAS drives require the use of a supported SAS HBA or RAID controller.

The drive bays are numbered as shown in the following figure.

Figure 7. Drive bay numbering (rear of the server)

The drive bays support 6Gb SATA drives or 12Gb SAS drives. NVMe drives are not supported.

The M.2 drives install into an M.2 adapter which in turn is installed in a dedicated slot on the system board. See the internal view of the server in the Components and connectors section for the location of the M.2 slot.

Supported drives are listed in the Internal drive options section.

For details about M.2 components, see the ThinkSystem M.2 Drives and M.2 Adapters product guide:
https://lenovopress.com/lp0769-thinksystem-m2-drives-adapters

The SR670 supports one of the following controllers to connect to the eight internal drive bays:

• SAS/SATA RAID adapter
• SAS HBA adapter
• Onboard SATA controller

The following table lists the supported adapters.

https://lenovopress.com/servers/options/hba

When installing the RAID 940-8i 4GB Flash adapter as a field upgrade, you will also need to order the ThinkSystem SR670 RAID 940 Upgrade Kit as listed in the following table. This kit is not required for factory orders that include the RAID adapter, as the necessary cables will automatically be derived by the configurator.

The onboard SATA controller onboard is integrated into the server chipset. An SFF-9402 OCulink x8 SATA connector routes the signals to the eight internal drive bays at the rear of the server. The SATA controller operates in either AHCI mode for JBOD support, or Intel RSTe mode for RAID support. In RSTe mode, Intel RAID features are accessible via XClarify Provisioning Manager (UEFI-based) where you can enabling RAID volumes of up to 8 drives. RAID levels 0, 1, 5, 10 are supported.

The following tables list the drive options for internal storage of the server.

The server does not supports any internal backup units, such as tape drives or RDX drives.

* SAS HBAs support SEDs (self-encrypting drives) by using software on the server and simply passing SED commands through the HBA to the drives.

The SR670 does not currently support any Flash Storage adapters.

The SR670 supports the GPUs listed in the following table.

Configuration notes:

• 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.

• When fewer than the maximum number of GPUs is installed, you can specify in the CTO factory order how you want the GPUs installed in the slots:
  • Distributed GPU Configuration: Indicates that GPUs are populated as equally as possible between the two processors
  • Concentrated GPU Configuration: Indicates that GPUs should fully populate all slots connected to CPU 1 first, and then once those slots are consumed, install the slots connected to CPU 2.

For details about these GPUs, consult the ThinkSystem GPU Summary, availlable from:
https://lenovopress.com/lp0768-thinksystem-gpu-summary

For customers that purchase the AMD Radeon Instinct MI25 directly from AMD, the required power cable is not included with the GPU. To use a customer-supplied MI25 GPU with the SR670, order the cable listed in the following table, one for each GPU to be installed.

The server has six 60 mm simple-swap fans and all six fans are standard in all models. The server offers N+1 fan redundancy, meaning that one fan can fail and the server still operates normally in typical datacenter environments. However, if the ambient temperate is above 27°C and a fan failure occurs, the GPUs may be instructed by the system to enter an emergency power reduction state whereby GPU performance will be impacted.

Each power supply has an integrated fan.

The server includes two 2000W hot-swap redundant power supplies. Both power supplies are standard.

The power supplies form a redundant pair in all server configurations except when the quantity of 250W (or greater) GPUs is three or more.

In such configurations, in the event of a single power supply failure, by default the server will proactively throttle the performance of the GPUs. This setting is configurable in UEFI. See the SR670 Information Center for details:
https://thinksystem.lenovofiles.com/help/topic/7Y37/gpu_power_braking.html?cp=3_8_10

The SR670 contains an integrated service processor, XClarity Controller (XCC), which provides advanced control, monitoring, and alerting functions. The XCC is based on the Pilot4 XE401 baseboard management controller (BMC) using a dual-core ARM Cortex A9 service processor.
