System architecture

The following figure shows the architecture of the SR950 at a high level. The system boards with processors and memory are installed in compute trays along with the drive bays and storage adapter. The I/O board houses all onboard PCIe slots as well as the slots for the riser cards the offer the remaining PCIe slots.

SR950 architecture
Figure 10. SR950 architecture

The specific connections between system boards, processors and PCIe slots are dependent on the server configuration. This is described in detail in the Server configurations section. Specific processor-slot connections based on each configuration are described in the Slot availability by server configuration section.

The following figure shows System board 1 where processors 1 and 2 are installed. The slots on the I/O board are connected directly to these processors (or indirectly through the Intel C624 Platform Controller Hub, PCH).

System board 1 connections to the I/O board
Figure 11. System board 1 connections to the I/O board

The processors within the chassis communicate via UltraPath Interconnect (UPI) ports. These ports allow high speed communication between the CPUs. UPI replaces the Intel QuickPath Interconnect (QPI). One UPI link connects the two processors on each system board (UPI 3) and the other two UPI links are used to connect the other processors in adjacent boards to form four-way and larger systems.

In four-processor configurations, the design of the UPI links is either in a mesh or a ring topology. When a processor has 3 UPI ports, it can be used in a 4-socket mesh configuration where all processors are directly connected to every other processor. 5200 Series processors only have 2 UPI ports (ports 1 and 2) and therefore do not support mesh topology. These two UPI configurations are shown in the following figure.

Mesh (left) and Ring (right) topologies for four-socket configurations
Figure 12. Mesh (left) and Ring (right) topologies for four-socket configurations

Ring topology with 8200 Series processors: As discussed in the Server configurations section, the “Four-Socket Upgradable / Storage Rich” configuration is a four-socket configuration that uses a Ring topology but uses 8200 Series processors.

The server supports an 8-socket configuration (8200 Series processors required). The following figure shows the UPI links used to connect eight processors.

8-socket topology
Figure 13. 8-socket topology

Refer to the processor options table for information on the number UPI links each processor option has for the SR950 system.

Server configurations

The SR950 supports five different configurations, depending on the desired number of processors, drive bays, PCIe slots, and upgradability to an 8-socket configuration.

Notes:

  • The configurations listed here represent Lenovo's recommendations regarding the selection of compute system boards, I/O riser cards, and NVMe drive bays to maximize the available resources. You can select fewer drives and lower slot counts by using lower-slot-count riser cards to meet application requirements.
  • The use of only two, three or six processors in configurations where supported will reduce the available I/O slots and NVMe drive bays. This is described in details in the Internal storage section and the I/O expansion options section.
  • Configurations 1 and 2 support either two, three or four processors, however the use 5200 Series processors requires that four processors be selected. Two or three 5200 Series processors are not supported in these configurations due to the way the processors are connected.
  • Configurations 3 and 4 are designed to be easily upgradable to 8 processors. As a result, 8200 Series processors are required.

When building a server in the configurator, the feature codes in the following table are key to selecting the right configuration.

Processors and memory are located on system boards installed in compute trays: 2 processors per system board, 2 system boards per compute tray, and 2 compute trays in the server.

Chipset Intel C624 chipset (formerly codenamed "Lewisburg")
Memory Up to 96 DIMM sockets (12 DIMMs per processor, installed on each system board). Lenovo TruDDR4 RDIMMs, LRDIMMs and 3DS RDIMMs are supported. Each processor has 6 memory channels, with 2 DIMMs per channel. DIMM slots are shared between standard system memory and persistent memory. DIMMs are available in three speeds: 2666 MHz, 2933 MHz and Performance+ 2933 MHz. Performance+ DIMMs support 2933 MHz with two DIMMs installed per channel (2DPC), whereas 2933 MHz DIMMs support 2933 MHz with only 1 DIMM per channel (1DPC).
Persistent memory Supports up to 48 Intel Optane DC Persistent Memory modules (DCPMMs) installed in the DIMM slots. Persistent memory is installed in combination with system memory DIMMs. Runs at 2666 MHz.

Processor options

The SR950 supports second-generation Intel Xeon Scalable processors in the Gold and Platinum levels.

The server supports up to four or eight processors, depending on the configuration selected, however processors are all installed within the 4U rack enclosure:

  • The use of more than 4 processors requires a Platinum-level processor.
  • For configurations that support up to eight processors, the server supports 2, 4, 6 or 8 processors.
  • For configurations of up to four processors (lower cost configuration, no upgrade path to eight processors), the server supports 2, 3 or 4 processors.

As described in the Components and connectors section, processors and memory are located on compute system boards - two processors per board. Two system boards are installed in a compute tray, and there are two compute trays in the server. 

The table below lists the supported second-generation Intel processors.

First generation processors: The SR950 also supports first-generation Xeon Scalable processors. For details, see https://lenovopress.com/lp0647.

All processors listed have the following characteristics:

  • Second-generation Intel Xeon Scalable processors (formerly codenamed "Cascade Lake")
  • 14 nm process technology
  • Six DDR4 memory channels
  • 48 PCIe 3.0 I/O lanes
  • 1 MB L2 cache
  • 1.375 MB or more L3 cache per core
  • Intel Hyper-Threading Technology
  • Intel Turbo Boost Technology 2.0
  • Intel Advanced Vector Extensions 512 (AVX-512)
  • Two or three Intel Ultra Path Interconnect (UPI) links at up to 10.4 GT/s

Some processors include a suffix letter in the processor model number:

  • L: Large memory tier (supports total memory up to 4.5TB per processor)
  • M: Medium memory tier (supports total memory up to 2TB per processor)
  • N: NFV optimized
  • S: Search optimized
  • T: High Tcase
  • U: Single socket
  • V: VM Density optimized
  • Y: Speed Select

Processors without a suffix, or those with a suffix other than M or L, support up to 1TB per processor.

B suffix: B is not an official suffix, but instead used by Intel to distinguish between the Xeon Gold 5218 and the Xeon Gold 5218B processors. These two processor models have the same core counts, frequencies, and features, however they are based on different die configurations. You should not install 5218 and 5218B processors in the same server.

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 of the total memory per processor includes both the system memory DIMMs and the Persistent Memory DCPMMs installed in the server.

For example:

  • A configuration using 12x 64GB DIMMs per processor is a total of 768 GB, which means that neither an M nor L processor is required
  • A configuration using 12x 256GB DIMMs per processor is a total of 3 TB, which means that an L processor is required
  • A configuration using 6x 32GB DIMMs + 6x 256GB DCPMMs is a total of 1.69 TB which means an M processor is required (an L processor may also be used)
  • A configuration using 6x 64GB DIMMs + 6x 512GB DCPMMs is a total of 3.375 TB which means an L processor is required
  • A configuration using 6x 256GB DIMMs + 6x 512GB DCPMMs is a total of 4.5 TB which means an L processor is required

Processor features

The following table compares the features of the supported second-generation Intel Xeon processors. The table lists the number of Intel Ultra Path Interconnect (UPI) ports each processor has. UPI ports are used to connect processors together for high-speed communications.

  • When a processor has 3 UPI ports, it can be used in a 4-socket mesh configuration where all processors are directly connected to every other processor. 5200 Series processors do not support mesh topology, since they only have 2 UPI ports.
  • When a processor has only 2 UPI ports, it can only be used in a 4-socket ring configuration where all processors are connected to the 2 adjacent processors and the fourth processor is only connected indirectly via another processor.

The mesh and ring topologies are shown in the following figure.

Mesh and ring processor topologies
Figure 14. Mesh and ring processor topologies

Abbreviations used in the table:

  • UPI: Ultra Path Interconnect
  • TDP: Thermal Design Power
  • FMA: Number of Intel AVX-512 Fused-Multiply Add (FMA) units
  • HT: Hyper-Threading
  • TB: Turbo Boost 2.0
  • VT: Virtualization Technology (includes VT-x and VT-d)
  • SST-PP: Speed Select Technology - Performance Profile
  • DCPMM: DC Persistent Memory Module support
  • RAS: Reliability, Availability, and Serviceability: Std = Standard, Adv = Advanced

The processors that support SST-PP offer three distinct operating points that are defined by a core count with a base speed associated with that core count. The operating point is selected during the boot process and cannot be changed at runtime.

Adding additional processors

For configurations with only one compute tray, you can upgrade to add a second compute tray. You can also add additional system boards as needed. The ordering information for these upgrades is listed in the following table.

Table 15. Compute tray and system board upgrades
Part number Feature code Description
7XG7A03955 B4Y1 ThinkSystem SR950 2-CPU, 24 DIMM Compute System Board v2
4C87A37049 B6E5 ThinkSystem SR950 Upper Compute Tray Kit with 19k fans, 6-8S Upgrade v2

The Compute System Board option, 7XG7A03955, includes the following components:

  • One compute system board, without processors or memory

Tip: The only difference between Compute System Board v2, and the original Compute System Board is that the v2 compute board provides sufficient power to support the new 19K RPM high-speed fans.

The Upper Compute Tray Kit, 4C87A37049, includes the following components:

  • 1x compute tray with 12 drive bays and 1 slot for storage adapter
  • 6x 19K RPM system fans
  • 1x Compute System Board v2
  • 3x 4-bay drive bay fillers

Note: The Upper Compute Tray Kit does not include drive backplanes

Memory

The SR950 with second-generation Intel Xeon Scalable processors uses Lenovo TruDDR4 memory operating at up to 2933 MHz. The server supports 12 DIMMs per processor, which corresponds to 48 DIMMs with four processors installed and 96 DIMMs when eight processors are installed. Each processor has six memory channels with two DIMMs per channel.

With 256 GB 3DS RDIMMs installed, an 8-socket server supports a total of 24 TB of system memory.

The SR950 with second-generation Intel Xeon Scalable processors also supports Intel Optane DC Persistent Memory, as described in the Persistent Memory section.

As described in the Components and connectors section, the memory is installed on compute system boards and there are two system boards per compute tray and one or two compute trays per server, depending on the configuration.

The SR950 with second-generation processors supports these memory DIMMs:

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

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 2933 MHz.

The following three tables lists the memory options that are available for SR950.

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 supports RDIMMs, LRDIMMs and 3DS RDIMMs. UDIMMs are not supported.
  • Mixing RDIMMs, LRDIMMs or 3DS RDIMMs is not supported.
  • Mixing x4 and x8 DIMMs is supported.
  • Mixing of 2666 MHz and 2933 MHz and 2933 MHz Performance+ DIMMs is supported, however, all installed memory will operate at the lowest speed.

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 6 or 12 per processor, so that all memory channels are used.
  • When mixing 16 GB and 32 GB DIMMs in the same configuration, use 16GB 2Rx8 DIMMs instead of 16 GB 1Rx4 DIMMs for better performance.
  • Populate memory channels so they all have the same total memory capacity.
  • Ensure all memory controllers on a processor socket have the same DIMM configuration.
  • All processor sockets on the same physical server should have the same DIMM configuration.

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.

Persistent Memory

The SR950 server supports Intel Optane DC Persistent Memory, a new class of memory and storage technology explicitly architected for data center usage. Persistent Memory offers significantly lower latency than fetching data from SSDs, even NVMe SSDs, and offers higher capacities than system memory.

Using Lenovo ThinkSystem servers running applications that are tuned for Intel Optane DC Persistent Memory will result in lower data latency compared to solid-state drive technology. When data is stored closer to the processor on nonvolatile media, applications can see significant overall improvement in performance. 

The following table lists the ordering information for the DC Persistent Memory modules (DCPMMs).

4ZC7A15112 B4LX ThinkSystem 512GB TruDDR4 2666MHz (1.2V) Intel Optane DC Persistent Memory 48 (6 per processor)

The following are the requirements when installing DCPMMs:

  • All second generation Intel Xeon Scalable Family processors that the SR950 supports also support DCPMMs. First generation Xeon Scalable processors are not supported.
  • All installed DCPMMs must be the same size. Mixing DCPMMs of different capacities is not supported
  • Maximum 6 DCPMMs per processor (install 1 in each memory channel)
  • Minimum 2 TruDDR4 DIMMs per processor (1 per memory controller)
  • For Memory Mode, minimum 2 DCPMMs per processor (install 1 per memory controller)
  • For App Direct Mode, minimum 1 DCPMM installed in the server (any processor)
  • When either Memory Mode or Mixed Mode is used, the ratio of memory to DCPMMs must be between 1:16 and 1:4, but the recommended ratio is 1:4 for the best performance. For example, 6x 16GB DIMMs + 2x 256GB DCPMMs is a ratio of 1:5.33. This ratio requirement does not apply to App Direct mode.
  • For each memory channel with both a DCPMM and a TruDDR4 DIMM installed, the DCPMM is installed in channel slot 1 (closest) and the DIMM is installed in channel slot 0
  • To maximize performance, balance all memory channels
  • In configurations with DCPMMs installed, memory mirroring is supported, with two restrictions:
    • Mirroring is only enabled on the DRAM DIMMs installed in the server; The DCPMMs themselves do not support mirroring.
    • Only App Direct mode is supported. Memory mirroring cannot be enabled when DCPMMs are in Memory Mode or Mixed Mode.
  • Memory sparing is not supported with DCPMMs installed

DCPMMs offer the following memory protection technologies:

  • ECC
  • SDDC
  • DDDC
  • Patrol scrubbing
  • Demand scrubbing

In the App Direct mode, the DCPMMs also support memory mirroring that is performed by the processor's integrated memory controllers. Memory mirroring is not supported in Memory Mode or Mixed Mode. Memory rank sparing is not supported by DCPMMs in any mode.

Internal storage

The SR950 offers up to 24x 2.5-inch drive bays, depending on the server configuration selected (as described in Server configurations). The server also supports either one or two M.2 drives, installed in an M.2 adapter.

In this section:

Backplanes and drive bays

Drives are all located at the front of the server, 12 drives at the front of the upper tray and 12 at the front of the lower tray. Drives are connected to 4-drive backplanes in a 2-by-2 configuration, as shown in the following figure. All drive bays are 2.5-inch form factor.

Location of backplanes
Figure 15. Location of backplanes

There are two different backplanes available for the SR950:

  • SAS/SATA backplane: Supports 4 SAS or SATA drives
  • AnyBay backplane:
    • Top two drives support SAS, SATA, or NVMe interface drives (Lenovo AnyBay)
    • Bottom two drive bays support SAS or SATA drives only

Regular 2.5-inch SAS/SATA drive bays support only SAS or SATA drives; however, the Lenovo AnyBay drive bay design allows a choice of SATA, SAS, or U.2 (NVMe) PCIe drives. This design enables the flexibility to configure some of the bays with high-performance PCIe SSDs while still using the other bays for high-capacity HDDs, which is an ideal solution for storage-tiering.

Backplane connections are as follows:

  • The 4-drive SAS/SATA backplane has one SAS/SATA connector and connects to a supported RAID controller or SAS HBA installed in the dedicated storage adapter slot.
  • The 4-drive AnyBay backplane has one SAS/SATA connector and connects to a supported RAID controller or SAS HBA plus one NVMe connector to connect to NVMe ports on one of the system boards in a compute tray or directly on the storage tray.

The SAS/SATA backplane is shown in the following figure.

SAS/SATA backplane
Figure 17. SAS/SATA backplane

Adapters and cabling

Each compute tray or storage tray includes one dedicated PCIe slot for a RAID adapter or SAS HBA.

Tip: The adapters are described in detail in the Controllers for internal storage section.

SAS/SATA backplanes are connected to the RAID adapter or HBA installed in the dedicated slot in that tray. AnyBay backplanes (NVMe support on 2 of the 4 drive bays) are connected to the RAID adapter or HBA or to an NVMe port adjacent to processor on a system board.

The following table lists which processor each SAS/SATA storage adapter and which NVMe port each backplane is connected to. Backplane numbering is shown in Figure 11.

Note: In 2, 3 and 6 processor configurations, the following backplanes cannot be AnyBay backplanes:

  • In 2-processor configurations, processors 3 and 4 are not installed; this means drive backplanes 1 and 2 cannot be AnyBay backplanes.
  • In 3-processor configurations, processor 3 is not installed; this means drive backplanes 1 and 4 cannot be AnyBay backplanes
  • In 6-processor configurations, processors 6 & 8 are not installed; this means drive backplanes 5 and 6 cannot be AnyBay backplanes

M.2 drives

The server supports one or two M.2 form-factor SATA drives for use as an operating system boot solution. With two M.2 drives configured, the drives are configured by default as a RAID-1 mirrored pair for redundancy.

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.

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

SED encryption key management with ISKLM

The server supports FIPS 140-2 self-encrypting drives (SEDs) as listed in the Internal drive options section. To effectively manage a large deployment of these drives in Lenovo servers, IBM Security Key Lifecycle Manager (SKLM) offers a centralized key management solution. A Lenovo Feature on Demand (FoD) upgrade is used to enable this SKLM support in the management processor of the server.

The following table lists the part numbers and feature codes for the upgrades.

I/O expansion options

The server supports the following PCIe slots, depending on the server configuration selected:

  • Slots 1-17 are PCIe 3.0 slots accessible from the rear of the server
  • One internal dedicated M.2 slot for an M.2 adapter located internally on the I/O tray
  • Two internal dedicated PCIe 3.0 x8 slots for storage adapters, located internally in each compute tray or storage tray

The following figure shows the locations of the slots at the rear of the server.

PCIe 3.0 slots at the rear of the server
Figure 18. PCIe 3.0 slots at the rear of the server

The 17 PCIe 3.0 rear-accessible slots are as follows:

  • Slots 1-4 are via Riser Slot 1, one riser card of:
    • Riser with 4x PCIe 3.0 x16 slots, all full-height half-length, all 75W
    • Riser with 2x PCIe 3.0 x16 slots, all full-height half-length, both 75W
    • Riser with 4x PCIe 3.0 x8 slots, full-height half-length, all 75W
  • Slot 5: PCIe 3.0 x16, low profile, 75W
  • Slot 6: PCIe 3.0 x16, low profile, 75W
  • Slot 7: PCIe 3.0 x8, low profile, 75W
  • Slot 8: PCIe 3.0 x16 ML2, low profile (supports NC-SI)
  • Slot 9: PCIe 3.0 x8 LOM adapter slot, low profile (supports NC-SI)
  • Slots 10-15 are via Riser Slot 2, one riser card of:
    • Riser 5x16+ML2
      • Five PCIe 3.0 x16 slots, all full-height half-length, all 75W
      • One PCIe 3.0 x16 ML2 slot, full-height half-length, 30W (no NC-SI support)
    • Riser 2x16: Two PCIe 3.0 x16 slots, all full-height half-length, both 75W
    • Riser 4x8: Four PCIe 3.0 x8 slots, full-height half-length, all 75W
  • Slot 16-17 on a riser:
    • PCIe 3.0 x8 low profile, 75W
    • PCIe 3.0 x8 low profile, 75W

Additional internal PCIe slots:

  • One or two PCIe 3.0 x8 slots for storage adapters, one in each compute tray
  • M.2 adapter slot

NC-SI (Network Controller Sideband Interface or NCSI) support means the primary port on the adapter installed in that slot can be configured as shared between XCC out-of-band management traffic and production Ethernet traffic.

For riser slots 1 and 2, the server supports the following three riser cards. These are shown in the figure below.

  • Riser 5x16+ML2:
    • Five PCIe 3.0 x16 slots, all full-height half-length, all 75W
    • One PCIe 3.0 x16 ML2 slot, full-height half-length, 30W (no NC-SI support)

    Note: When the 5x16+ML2 riser is installed in riser slot 1, the bottom two slots (including the ML2) are not accessible and cannot be used.

  • Riser 2x16: Two PCIe 3.0 x16 slots, all full-height half-length, both 75W
  • Riser 4x8: Four PCIe 3.0 x8 slots, full-height half-length, all 75W

Note: The ML2 slot on the riser card does not support NC-SI.

Riser cards for riser slots 1 and 2
Figure 19. Riser cards for riser slots 1 and 2

Slot numbering is as follows:
  • When installed in riser slot 1:
    • Riser 5x16+ML2 becomes slots 1-4 (bottom two slots inaccessible)
    • Riser 2x16 becomes slots 3-4
    • Riser 4x8 becomes slots 1-4
  • When installed in riser slot 2:
    • Riser 5x16+ML2 becomes slots 10-15
    • Riser 2x16 becomes slots 12-13
    • Riser 4x8 becomes slots 10-13

Note: When the 5x16+ML2 riser card is used in Riser slot 1, only the top 4 slots (all x16) are accessible. The lower x16 and x16 ML2 slots cannot physically be accessed or used.

Slots 16 and 17 are mounted on a single 2x8 riser card and are as follows:

  • Slot 16: PCIe 3.0 x8, full-height half-length, 75W
  • Slot 17: PCIe 3.0 x8, full-height half-length, 75W

Network adapters

The SR950 has an integrated 10Gb Ethernet controller, based on the Intel Ethernet Connection X722. The X722 has the following features:

  • Integrated into the Intel PCH chipset
  • Supports 1GbE or 10GbE connections, depending on the selected LOM Phy adapter
  • Offers VXLAN/NVGRE hardware offloads
  • Supports VMDq and SR-IOV for advanced virtualization
  • Supports iWarp RDMA

To provide connectivity to the X722, the SR950 supports six different LOM (LAN on Motherboard) cards which provide the Ethernet PHY function. Only 1 LOM card can be installed. See Figure 3 for the location of the LOM slot.

The LOM card supports NC-SI to allow the network connection to be shared between the operating system and the XClarity Controller (XCC) management module. The LOM also supports Wake-on-LAN (WOL).

For more information about the X722 controller, see the Lenovo Press product guide:
http://lenovopress.com/lp0654-intel-x722-integrated-controller

The following table lists the supported LOM cards.

GPU adapters and coprocessors

Full-length adapter cards such as graphics processing units (GPUs) do not physically fit in the server and are not supported.

Cooling

The SR950 uses a set of 60mm hot-swap single-rotor fans for system-wide cooling. Each compute tray or storage tray houses 6 hot-swap fans. The 6 fans in the compute tray are N+1 redundant, meaning that a single fan failure is tolerated in each compute tray.

Fans are located internal to the server immediately in front of the compute system boards, but are accessible from the front of the server by the long handle attached to the fan. As the handle is pulled out, the attached fan rotates from vertical orientation to horizontal orientation, allowing the fan to be removed from the system using the handle, as shown below.

Six fans installed in the compute tray
Figure 21. Six fans installed in each compute tray (lower compute tray shown)

New SR950 servers with second-generation Intel Xeon Scalable processors will use 19K RPM fans. These faster fans ensure that all eight-socket configurations will run up to their supported ASHRAE ambient temperatures as stated in the Operating environment section.

Note: SR950 servers that were upgraded to second-generation Intel Xeon Scalable processors from first-generation processors will still use the original 16K RPM fans and will continue to have the situation where an eight-socket 205W processor configuration may experience a slight drop in performance under extreme workloads when the ambient temperature is above 30°C.

Power supplies

The server supports up to four hot-swap power supplies. Power supplies are N+N redundant, which means that if the server has four power supplies installed, then the server can continue operation even with two failed power supplies, or if the utility service that feeds those two power supplies goes offline.

All power supplies installed in a server must have the same capacity (for example all 1600W).

Note: At 100-127 V AC input, the 1100W power supply is limited to 1050W.

Power supply options do not include a power cord. For models of the SR950, the inclusion of a power cords is model dependent. Configure-to-order models can be configured without a power cord if desired.

See Physical and electrical specifications for additional information.

Tip: Use Lenovo Capacity Planner to determine exactly what power your server needs:
https://datacentersupport.lenovo.com/us/en/products/solutions-and-software/software/lenovo-capacity-planner/solutions/ht504651

Power cords

Line cords and rack power cables can be ordered as listed in the following table.

110V customers: If you plan to use the ThinkSystem 1100W power supply with a 110V power source, select a power cable that is rated above 10A. Power cables that are rated at 10A or below are not supported with 110V power.

Integrated virtualization

The server supports booting from an operating system or hypervisor installed on an M.2 solid-state drive. See the M.2 drives section for details and the list of available options.

You can download supported VMware vSphere hypervisor images from the following web page and load it on the M.2 drive using the instructions provided:
https://vmware.lenovo.com/content/custom_iso/

Systems management

The server contains an integrated service processor, XClarity Controller (XCC), which provides advanced service-processor 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.

Local management

The SR950 offers the front operator panel showing key LED status indicators, as shown in the following figure.

Front operator panel
Figure 22. Front operator panel (LCD display panel closed)

The front operator panel pulls out (see the release latch in the above figure) to show an LCD display panel and buttons, as shown in the following figure. The LCD display panel allows quick access to system status, firmware, network, and health information.

Front operator panel with LCD display
Figure 23. LCD display panel

The LCD display and the function buttons give you access to the following information:

  • Error messages
  • System VPD: machine type & mode, serial number, UUID string
  • System firmware levels: UEFI and XCC firmware
  • XCC network information: hostname, MAC address, IP address, DNS addresses
  • Environmental data: Ambient temperature, CPU temperature, AC input voltage, estimated power consumption
  • System reset action

If an environmental condition exceeds a threshold or if a system component fails, XCC illuminates LEDs inside the server to help you diagnose the problem and find the failing part. The SR950 has fault LEDs next to the following components:

  • Each processor
  • Each memory DIMM
  • Each system fan
  • Each power supply
  • Each rear-facing PCIe slot 
  • Each drive bay

For local console use, the SR950 has both a front and rear VGA port. Only one can be active at a time. If displays are connected to both VGA ports, the front VGA port takes precedence. 

System status with XClarity Mobile

The XClarity Mobile app includes a tethering function where you can connect your Android or iOS device to the server via USB to see the status of the server.

The steps to connect the mobile device are as follows:

  1. Enable USB Management on the server, by holding down the ID button for 3 seconds (or pressing the dedicated USB management button if one is present)
  2. Connect the mobile device via a USB cable to the server's USB port with the management symbol USB Management symbol
  3. In iOS or Android settings, enable Personal Hotspot or USB Tethering
  4. Launch the Lenovo XClarity Mobile app

Once connected you can see the following information:

  • Server status including error logs (read only, no login required)
  • Server management functions (XClarity login credentials required)

Remote management

Remote server management is provided through industry-standard interfaces:

  • Intelligent Platform Management Interface (IPMI) Version 2.0
  • Simple Network Management Protocol (SNMP) Version 3 (no SET commands; no SMNP v1)
  • Common Information Model (CIM-XML)
