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

The following table lists the available models.

Models for EMEA regions

The SR850 supports Gold and Platinum level processors in the second-generation Intel Xeon Processor Scalable Family.

Topics in this section:

• Continued support for 1st Gen Intel Xeon Scalable processors
• Memory capacity of processors
• Processor features
• UEFI operating modes

The server supports two or four processors.

• Processors 1 and 2 are installed in sockets on the system board.
• Processors 3 and 4 are installed on the Processor and Memory Expansion Tray.

The Processor and Memory Expansion Tray has a patent-pending sliding and rolling lift mechanism that requires only a one-handed operation to insert or remove from the server. It has a toolless design for superior usability, serviceability and reliability. 

Figure 6. SR860 Processor and Memory Expansion Tray

The ordering information for the Processor and Memory Expansion Tray is shown in the following table.

The following processor quantities are supported:

• Two processors, installed in sockets 1 and 2, without the Processor and Memory Expansion Tray
• Four processors, installed in all four sockets

Note: Configurations of one or three processors are not supported.

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

All supported processors 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)
• Intel Ultra Path Interconnect (UPI) links at 10.4 GT/s (replaces QPI)

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 support up to 1TB per processor.

With two processors installed, the two processors are connected together using one UPI link. With four processors installed, the processors are connected together using a ring topology, using two UPI links, one to each adjacent processor in the ring.

For specifications of these processors, see the Intel Xeon Scalable Processor Reference for Lenovo ThinkSystem Servers:
https://lenovopress.com/lp1262-intel-xeon-sp-processor-reference#term=SKL

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 8260L): Up to 4.5 TB per processor
• Processors with an M suffix (eg 8260M): Up to 2 TB per processor (now withdrawn)
   
• 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 an L processor is required
• A configuration using 12x 128GB DIMMs per processor is a total of 1.5 TB, which means that an M 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 128GB DIMMs + 6x 512GB DCPMMs is a total of 3.75 TB which means an L processor is required

Processor features

The following table lists 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 SR860 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 SR860, 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 SR860 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. Each processor has six memory channels with two DIMMs per channel.

With 128 GB 3DS RDIMMs installed, a 4-socket server supports a total of 6 TB of system memory.

The SR860 with second-generation Intel Xeon Scalable processors also supports Intel Optane DC Persistent Memory, as described in the Persistent Memory section.

With second-generation processors, the server 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 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. 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 2933 MHz Performance+ DIMMs with other DIMMs or Persistent Memory is not supported
• Mixing of 2666 MHz and 2933 MHz and 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.

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 SR860 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).

The following are the requirements when installing DCPMMs:

• All second generation Intel Xeon Scalable Family processors that the SR860 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, mimimum 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.

The server can support up to 16x 2.5-inch drives, SAS, SATA or NVMe, depending on the selected backplane configuration. You can mix drives in the same server, but not in the same array. Drives are all installed from the front of the server. The server also supports one or two M.2 drives, installed in an M.2 adapter.

In this section:

• Backplanes and drive bays
• Processors with backplane restrictions
• Adapters and cabling
• Field upgrades
• M.2 drives
• SED encryption key management with ISKLM

Backplanes and drive bays

The SR860 supports various internal storage configurations based on two different backplanes:

• 8-drive SAS/SATA backplane for 8x 2.5-inch SAS or SATA drives
• 8-drive SAS/SATA+AnyBay backplane for either:
  • 8x 2.5-inch SAS or SATA drives
  • 4x 2.5-inch SAS or SATA drives + 4x 2.5-inch U.2 (NVMe) drives

For configure-to-order (CTO) configurations, ordering information for the backplanes is in the following table.

* Backplanes are configure-to-order (CTO) only; however, upgrade kits are available that include backplanes, as described in the Field upgrades section below.

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 NVMe drives. This design enables the flexibility to configure some of the bays with high-performance PCIe SSDs and still use the remaining bays for high-capacity HDDs, which is the ideal solution for storage tiering.

Backplane connections are as follows:

• The 8-drive SAS/SATA backplane has two SAS/SATA connectors and connects to a supported RAID controller or SAS HBA.
• The 8-drive SAS/SATA+AnyBay backplane has two SAS/SATA connectors and connects to a supported RAID controller or SAS HBA plus four PCIe connectors to connect to either two PCIe connectors on the Processor and Memory Expansion Tray (see Figure 4), or four PCIe connectors on a NVMe Switch adapter installed in a PCIe slot.

Five drive configurations are possible with these two backplanes:

1. 8 drive bays, all SAS/SATA
2. 8 drive bays, where 4 are AnyBay
3. 16 drive bays, all SAS/SATA
4. 16 drive bays, where 4 are AnyBay
5. 16 drive bays, where 8 are AnyBay
6. Zero drive bays without any backplanes installed

The first five configurations are shown in the following figure.

Figure 7. Drive bay configurations

Field upgrades

This section describes how customers can upgrade their 8-bay configurations after the initial purchase of the server. The two backplane upgrade kits are listed in the following table.

The table also lists cable kits for when you already have the backplanes installed and either want to add a storage adapter or replace a storage adapter. The X30 RAID Cable Kit is for 930/730/530/430 adapters (collectively called X30 adapters) and the X40 RAID Cable Kit is for 940/440 adapters (collectively called the X40 adapters).

In addition to the backplane kits, you will need a RAID adapter or HBA, and for some upgrades you may also need an NVMe adapter. Upgrades needed are listed in the following two tables. Upgrading from an 8-port SAS/SATA adapter to a 16-port SAS/SATA adapter is supported, however that requires removing the existing 8-port adapter.

The following table lists the available upgrades for SR860 servers with a single SAS/SATA backplane (See Configuration 1 above).

The following table lists the available upgrades for SR860 servers with a single SAS/SATA backplane (See Configuration 2 above).

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

• When the M60 is installed, the total system memory must be less than 1 TB. See https://support.lenovo.com/us/en/solutions/ht114952 for details.
• When the V100 is installed:
  • Two power supplies must be installed and they must be 2000W capacity
  • Processors must have TDP rating < 200W
  • XCC firmware dated 24 April 2018 or later must be installed
• If 1 GPU is installed, an 1100W power supply or larger must be installed
• If 2 GPUs are installed, a 1600W power supply or larger must be installed

The server has six 60 mm hot-swap fans and all six fans are standard in all models. The server offers N+1 redundancy, meaning that one fan can fail and the server still operates normally.

Either 16K RPM fans or 19K RPM fans are used in the server, depending on the components used in the server.

In addition, each power supply has an integrated fan and a fan is connected to each of the two upper riser units.

The 16K fan is the default selection, however the 19K fan is automatically selected when any DCPMMs or processors with high thermal characteristics is selected:

• Any quantity and capacity of DCPMMs
• Intel Xeon Gold 6240Y 18/14/8C 150W Processor
• Intel Xeon Gold 6244 8C 165W 3.6GHz Processor
• Intel Xeon Gold 6246 12C 165W 3.3GHz Processor
• Intel Xeon Gold 6252N 24C 150W 2.3GHz Processor
• Intel Xeon Gold 6254 18C 200W 3.1GHz Processor
• Intel Xeon Platinum 8268 24C 205W 2.9GHz Processor
• Intel Xeon Platinum 8270 26C 205W 2.7GHz Processor
• Intel Xeon Platinum 8280 28C 205W 2.7GHz Processor
• Intel Xeon Platinum 8280L 28C 205W 2.7GHz Processor
• Intel Xeon Platinum 8280M 28C 205W 2.7GHz Processor

The only thermal restriction with the use of 19K fans is if any DCPMMs are installed. In such configurations, the maximum ambient temperature can be 30 °C. If the ambient temperate exceeds 30 °C, or in the event of a fan failure, the server will continue to function as long as all component temperature requirements are met, however, there may be performance reductions.

For existing customers with the original 16K fans wish to operate the server without restrictions other than the above DCPMM ambient temperature requirement, the 19K RPM fans can be installed as field upgrades using part number 4F17A60142. The part number contains 1 fan. A total of 6 fans will need to be ordered.

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

Installing a second power supply requires either the Processor and Memory Expansion Tray (7B27A03953) or the power interposer (feature AUPZ).

The power interposer enables redundant power support when the Processor and Memory Expansion Tray is not installed. If you do not have the Processor and Memory Expansion Tray installed and want to install two power supplies, then the power interposer card must be installed.

* Configure-to-order only
** Only needed if two power supplies are installed but the Processor and Memory Expansion Tray is not installed

750W and 1100W power supplies are auto-sensing and support both 110V AC (100-127V 50/60 Hz) and 220V AC (200-240V 50/60 Hz) power. The 1600 W and 2000 W power supplies only supports 220V AC power.

For China customers, all power supplies support 240V DC.

Note: At 110 V, the 1100W power supply generates 1050W of power.

Power supply options do not include a line cord.

For server configurations, the inclusion of a power cord is model dependent. Configure-to-order models can be configured without a power cord if desired.

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/

The server 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.

As an alternative to the front operator panel, (certain models or configure-to-order; not available as a field upgrade), the server supports a pull-out LCD display panel. The LCD display panel allows quick access to system status, firmware, network, and health information. The following figure shows the front operator panel with LCD display.

Figure 16. Front operator panel with LCD display

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

• Error messages
• System VPD: machine type & model, 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

The front operator panel with LCD display can be ordered as listed in the following table.

* Only available configure-to-order or with predefined models

The server offers light path diagnostics. If an environmental condition exceeds a threshold or if a system component fails, the XCC lights LEDs inside the server to help you diagnose the problem and find the failing part. The SR860 has fault LEDs next to the following components:

• Each processor
• Each memory DIMM
• Each drive bay
• Each system fan
• Each power supply

The front of the server also houses an information pull-out tab (also known as the network access tag). See Figure 2 for the location. A label on the tab shows the network information (MAC address and other data) to remotely access XClarity Controller.

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
3. In iOS or Android settings, enable Personal Hotspot or USB Tethering
4. Launch the Lenovo XClarity Mobile app

Remote management

The server offers a dedicated RJ45 port at the rear of the server for remote management via the XClarity Controller management processor. The port supports 10/100/1000 Mbps speeds.

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)
• Representational State Transfer (REST) support
• Redfish support (DMTF compliant)
• Web browser - HTML 5-based browser interface (Java and ActiveX not required) using a responsive design (content optimized for device being used - laptop, tablet, phone) with NLS support

IPMI via the Ethernet port (IPMI over LAN) is supported, however it is disabled by default. For CTO orders you can specify whether you want to the feature enabled or disabled in the factory, using the feature codes listed in the following table.

A virtual presence (remote control) capability also comes standard in the server for remote server management. Virtual media (remote drive images) support is optional via a software license upgrade.

Because Lenovo XClarity Administrator does not require any agent software to be installed on the managed endpoints, there are no CPU cycles spent on agent execution, and no memory is used, which means that up to 1GB of RAM and 1 - 2% CPU usage is saved, compared to a typical managed system where an agent is required.

Lenovo XClarity Administrator is an optional software component for the SR860. The software can be downloaded and used at no charge to discover and monitor the SR860 and to manage firmware upgrades.

If software support is required for Lenovo XClarity Administrator, or premium features such as configuration management and operating system deployment are required, Lenovo XClarity Pro software subscription should be ordered. Lenovo XClarity Pro is licensed on a per managed system basis, that is, each managed Lenovo system requires a license.

The following table lists the Lenovo XClarity software license options.
