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.

The ThinkSystem SR670 with Intel Xeon SP Gen 1 processors does not have standard models. Order the server using configure-to-order (CTO) in the Lenovo DCSC or x-config configurators:

• DCSC: https://dcsc.lenovo.com/
• x-config: https://lesc.lenovo.com/products/hardware/configurator/worldwide/bhui/asit

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

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

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 per core (except where larger, as noted with ** in the table below)

• 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)

** L3 cache is 1.375 MB per core except for processor indicated with ** where the cache size is larger

The SR670 server supports TruDDR4 memory. TruDDR4 memory uses the highest-quality components sourced from Tier 1 DRAM suppliers and only memory that meets strict tolerances is selected. It is compatibility tested and tuned to maximize performance and reliability.

TruDDR4 memory has a unique signature programmed into the DIMM, which enables ThinkSystem servers to verify whether the memory installed is qualified and supported. From a service and support standpoint, TruDDR4 memory automatically assumes the system's warranty, and service and support provided worldwide.

The server supports 8, 12, 16 or 24 DIMMs with the two processors installed. Each processor has six memory channels, and supports one or two DIMMs per channel.

All DIMMs can operate at a speed of 2666 MHz, both at 1 DIMM per channel and 2 DIMMs per channel. However, if the processor selected has a lower memory bus speed (eg 2400 MHz), then all DIMMs will operate at that lower speed.

The following table lists the memory options that are available for the SR670 server.

Configuration rules:

• The server supports RDIMMs. LRDIMMs, 3DS RDIMMs and 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.

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 channel mirroring
• Memory rank sparing

If memory channel mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per processor), and both DIMMs in a pair 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 one quad-rank DIMM, one dual-rank DIMM, or two single-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.

The SR670 supports the GPUs listed in the following table.

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. Such GPUs includes the double-wide NVIDIA V100, NVIDIA P40 and AMD MI25 GPUs.

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.

The PCIe slots in the SR670 are all front-accessible. This means that top-of-rack networking switches would normally be installed at the front of the rack and all switches would have front-to-rear airflow (Opposite Port Side Exhaust or oPSE).

If desired, switches with traditional air flow (rear to front) can also be used, with such switches installed at the rear of the rack and cables routed to the front of the rack to connect to the network ports of the SR670 server.

• 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.
