Key features

This section describes the key features of the server.

Scalability and performance

The SN850 offers the following features to boost performance, improve scalability, and reduce costs:

  • Up to 7 SN850 servers can be installed in one Flex System Enterprise chassis.
  • Improves productivity by offering superior system performance with up to 28-core processors, 38.5 MB of L3 cache, up to three 10.4 GT/s Ultra Path Interconnect links and a Thermal Design Power (TDP) rating of up to 165W.
  • Supports up to four processors, 112 cores, and 224 threads, which maximizes the concurrent execution of multi-threaded applications. When four processors are installed, they are connected in a Mesh topology to maximize inter-processor communication (requires processors with three UPI connections)
  • Intelligent and adaptive system performance with energy-efficient Intel Turbo Boost Technology allows CPU cores to run at maximum speeds during peak workloads by temporarily going beyond processor TDP.
  • Intel Hyper-Threading Technology boosts performance for multithreaded applications by enabling simultaneous multithreading within each processor core, up to two threads per core.
  • Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating system vendors to better use the hardware for virtualization workloads.
  • Intel Advanced Vector Extensions 512 (AVX-512) enable acceleration of enterprise-class workloads, such as databases and enterprise resource planning.
  • Each processor has 6 memory channels with up 2 two DIMMs per channel running at up to 2666 MHz.
  • Up to 3.0 TB using 48x 64 GB LRDIMMs (all processors) or 6.0 TB using 48x 128 GB 3DS RDIMMs (requires M-suffix processors).
  • Optional support for high-performance PCIe-attached NVMe Flash Storage solid-state drives (SSDs) can significantly improve I/O performance.
  • Embedded 4-port 10Gb Intel adapter built into the system board is based on the Intel Ethernet Connection X722 network controller.
  • With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon processor Scalable family. This integration helps to dramatically reduce I/O latency and increase overall system performance.
  • Support for high-bandwidth I/O adapters; up to four in each SN850 server.
  • Support for 40 Gb Ethernet, 16 Gb Fibre Channel, and FDR InfiniBand.
  • High-speed USB 3.0 port for connectivity to external devices.

Availability and serviceability

The SN850 provides the following features to simplify serviceability and increase system up-time:

  • The server offers Single Device Data Correction (SDDC, also known as Chipkill), Adaptive Double- Device Data Correction (ADDDC, also known as Redundant Bit Steering or RBS), memory mirroring, and memory rank sparing for redundancy in the event of a non-correctable memory failure.
  • Tool-less cover removal provides easy access to upgrades and serviceable parts, such as CPU, memory, and adapter cards.
  • The Dual M.2 Boot Adapter supports RAID-1 which enables two installed M.2 drives to be configured as a redundant pair.
  • Hot-swap drives support integrated RAID-1 redundancy for data protection and greater system up-time.
  • Solid-state drives (SSDs), which offer significantly better reliability than mechanical HDDs for greater uptime. 
  • The power source independent light path diagnostics functionality provides individual LEDs that lead the technician to failed (or failing) components, which simplifies servicing, speeds up problem resolution, and helps improve system availability.
  • The built-in XClarity Controller continuously monitors system parameters, triggers alerts, and performs recovery actions in case of failures to minimize downtime.
  • Proactive Platform Alerts (including PFA and SMART alerts): Processors, voltage regulators, memory, internal storage (SAS/SATA HDDs and SSDs, NVMe SSDs, flash storage adapters), RAID controllers, and server ambient and sub-component temperatures. Alerts can be surfaced through the system XClarity Controller to managers such as Lenovo XClarity Administrator, VMware vCenter, and Microsoft System Center. These proactive alerts let you take appropriate actions in advance of possible failure, thereby increasing server uptime and application availability.
  • Built-in diagnostics in UEFI, using Lenovo XClarity Provisioning Manager, speed up troubleshooting tasks to reduce service time, and supports diagnostic function and to collect service data to USB key drive or remote CIFS share folder.
  • Auto-restart in the event of a momentary loss of AC power (based on power policy setting in the XClarity Controller service processor). 
  • Support for the XClarity Administrator Mobile app running on a supported smartphone and connected to the server through the service-enabled USB port, enables additional local systems management functions.
  • Three-year customer replaceable unit and on-site limited warranty; next business day 9x5. Optional service upgrades are available.

Manageability and security

The following powerful systems management features simplify the local and remote management of the SN850:

  • Support for Lenovo XClarity Administrator, providing auto-discovery, inventory tracking, monitoring, policy-based firmware updates, address pool management, configuration patterns and operating system installation.
  • The server includes an XClarity Controller (XCC) to monitor server availability and perform remote management. XCC Advanced is supported as standard, which enables remote KVM, mounting of remote media files (ISO and IMG image files), boot capture, and power capping.
  • New UEFI-based Lenovo XClarity Provisioning Manager, accessible from F1 during boot, provides system inventory information, graphical UEFI Setup, platform update function, RAID Setup wizard, operating system installation function, and diagnostic functions
  • Integrated Trusted Platform Module (TPM) 2.0 support enables advanced cryptographic functionality, such as digital signatures and remote attestation.
  • Supports Secure Boot to ensure only a digitally signed operating system can be used. Supported with HDDs and SSDs as well as M.2 drives.
  • Support for Lenovo XClarity Energy Manager which captures real-time power and temperature data from the server and provides automated controls to lower energy costs.
  • Industry-standard Advanced Encryption Standard (AES) NI support for faster, stronger encryption.
  • Intel Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow attacks when combined with a supporting operating system.
  • Intel Trusted Execution Technology provides enhanced security through hardware-based resistance to malicious software attacks, which allows an application to run in its own isolated space that is protected from all other software that is running on a system.

Energy efficiency

The SN850 offers the following energy-efficiency features to save energy, reduce operational costs, increase energy availability, and contribute to a green environment:

  • The component-sharing design of the Flex System chassis provides ultimate power and cooling savings.
  • The Intel Xeon Processor Scalable Family of processors offer significantly better performance than previous generations of processors, while fitting into the same TDP limits.
  • Intel Intelligent Power Capability powers individual processor elements on and off as needed, which reduces power draw.
  • Solid state drives (SSDs) use as much as 80% less power than traditional spinning 2.5-inch HDDs.
  • The SN850 uses hexagonal ventilation holes which can be grouped more densely than round holes, providing more efficient airflow through the system.

Processor options

The SN850 supports the Intel Xeon Processor Scalable Family options that are listed in the following table. The server supports two or four processors. When four processors are installed, they are connected in the Mesh topology to maximize inter-processor communication (requires processors with three UPI connections).

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 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)

Depending on the processor model installed, the processors are connected together using either two or three UPI links. Processors with a T suffix are those that have more robust thermal characteristics (higher T-case). Processors with an M suffix support support greater than 768 GB per processor.

Note: The SN850 processor part numbers listed include two processors.

Memory options

The SN850 uses Lenovo TruDDR4 memory operating at speeds up to 2666 MHz.

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 on every ThinkSystem server to maximize performance and reliability. TruDDR4 Memory has a unique signature that is programmed into the DIMM that enables ThinkSystem servers to verify whether the memory that is installed is qualified and supported by Lenovo.

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

All DIMMs 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 SN850 server.

The following rules apply when selecting the memory configuration:

  • The server supports RDIMMs, LRDIMMs and 3DS RDIMMs. UDIMMs are not supported.
  • Mixing RDIMMs and LRDIMMs is not supported.
  • Mixing 3DS RDIMMs with either RDIMMs or LRDIMMs is not supported.
  • Mixing x4 and x8 DIMMs is supported.
  • For best performance, populate memory DIMMs in quantities of 6 or 12 per processor, so that all memory channels are used.

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; Gold and Platinum processors only)
  • Memory channel 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 one quad-rank DIMM or 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.

Internal storage

The SN850 server has four 2.5-inch hot-swap drive bays that are accessible from the front of the blade server (see Figure 2). Depending on server configuration and installed backplanes, these bays connect to either the integrated 6 Gbps SATA controller, optional Lenovo RAID controllers or directly to PCIe lanes for NVMe drives.

In addition, the SN850 can also support one or two M.2 form factor SSD drives on a separate adapter. The following table lists the supported M.2 adapters (enablement kits). For more information, see the ThinkSystem M.2 Drives and M.2 Adapters product guide: https://lenovopress.com/lp0769-thinksystem-m2-drives-adapters

Virtualization support: The integrated SATA controller can be used with virtualization hypervisors, including VMware ESXi, Linux KVM, Xen, and Microsoft Hyper-V. However, support is limited to AHCI (non-RAID) mode. RSTe mode is not supported with virtualization hypervisors.

Internal tape drives

The server does not support an internal tape drive. However, it can be attached to external tape drives by using Fibre Channel connectivity.

Optical drives

The server does not support an internal optical drive option, however, you can connect an external USB optical drive. See https://datacentersupport.lenovo.com/us/en/documents/pd011281 for information about available external optical drives from Lenovo. Alternatively, use the remote media feature of the XClarity Controller and the Chassis Management Module.

Embedded 10Gb Network Adapter

The SN850 includes an embedded 4-port 10Gb Intel controller built into the system board. As listed in the Models section, some SN850 models include the Fabric Connector needed to connect the embedded controller to the midplane of the Flex System chassis. For models that do not include the Fabric Connector, it can be ordered and installed in the field. Ordering information is listed in the following table.

Table 24. Fabric Connector ordering information
Part number Feature code Description
7M27A03927 AUYN Lenovo ThinkSystem Server Fabric Connector

The location of the fabric connector is shown below.


Figure 6. Location of fabric connector in SN850 server

Table 25 and Figure 9 show how the 4 ports of the embedded controller connect through the Fabric Connector to the corresponding I/O module ports. The Fabric Connector can be removed, if required, to allow the installation of an I/O adapter on I/O connector 3.

The embedded 10Gb controller is based on the Intel Ethernet Connection X722 network controller which is part of the Intel C624 "Lewisburg" PCH chipset of the SN850 and other Lenovo ThinkSystem servers.

The Intel X722 controller is optimized for data center, cloud, and mobile applications and includes the following features:

  • VXLAN/NVGRE Hardware Offloads: These stateless offloads preserve application performance for overlay networks. With these offloads, it is possible to distribute network traffic across CPU cores. At the same time, the controller offloads LSO, GSO, and checksum from the host software, which reduces CPU overhead.
  • Low latency: Intel Ethernet Flow Director delivers hardware-based application steering and Intel Data Direct I/O makes the processor cache the primary destination and source of I/O data rather than main memory.
  • Virtualization performance: With Intel Virtualization Technology (VT), the controller delivers outstanding I/O performance in virtualized server environments. The controller reduces I/O bottlenecks by providing intelligent offloads for networking traffic per virtual machine (VM), which enables near-line rate speeds for small packets and supports almost an unlimited amount of isolated traffic flows so that you can scale your cloud environment.
  • Next-generation VMDq: The controller supports up to 128 VMDq VMs and offers enhanced Quality of Service (QoS) by providing weighted round-robin servicing for the Tx data. The controller offloads the data-sorting functionality from the hypervisor to the network silicon, which improves data throughput and CPU usage.
  • SR-IOV implementation: Provides an implementation of the PCI-SIG standard for I/O Virtualization. The physical configuration of each port is divided into multiple virtual ports. Each virtual port is assigned to an individual VM directly by bypassing the virtual switch in the Hypervisor, which results in near-native performance.
  • iWarp RDMA support implements kernel bypass and direct data placement and allows for more efficient high-speed networking by eliminating queues and network related interrupts
  • VM load balancing: Provides traffic load balancing (Tx and Rx) across VMs that are bound to the team interface. It also provides fault tolerance if a switch, port, or cable fails or is disconnected.
  • Auto-detect (PnP) feature for the LOM adapters, enabling you to change speed (eg from a 1Gb LOM to 10 Gb LOM) and the network interface will automatically reconfigure during the boot process.

Note: The onboard Ethernet controller does not support 10 Mb or 100 Mb Ethernet connections.

I/O expansion options

The SN850 has four I/O expansion connectors for attaching I/O adapter cards. The I/O expansion connectors use a high-density, 216-pin PCIe connection. Installing I/O adapter cards allows the server to connect with I/O modules in the chassis. Each slot has a PCI Express 3.0 x16 host interface and all slots support the same form-factor adapters.

The following figure shows the location of the I/O expansion connectors.


Figure 7. Location of the I/O adapter slots in the SN850 server

All I/O adapters are the same form factor. A compatible switch or pass-through module must be installed in the corresponding I/O bays in the chassis, as indicated in the following table. Installing two switches means that all ports of the adapter are enabled, which improves performance and network availability.

Network adapters

In addition to the embedded Intel 4-port 10Gb controller (model specific), the SN850 supports other network adapters that can be installed in IO slots.

The following table lists the supported network adapters and upgrades. Adapters can be installed in any slot. However, compatible switches must be installed in the corresponding bays of the chassis.

Power supplies

Power to the blade server is derived from the power supplies that are installed in the chassis. There are no server options regarding power supplies.

System 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

As shown in Figure 2, the SN850 front panel includes a USB port, status indicators, a button to enable management via the USB port and a console breakout cable port. The breakout cable (supplied with the chassis) provides serial, video and a USB port for connecting a local console. The USB ports on the breakout cable support keyboard and mouse; storage devices are not supported.

System status with XClarity Mobile

The Lenovo XClarity Mobile (LXCM) app now 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 pressing and holding for 3 seconds the dedicated USB management button on the front of the server.
  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

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)

Light Path Diagnostics

The SN850 includes light path diagnostics. If an environmental condition exceeds a threshold or if a system component fails, XCC lights LEDs inside the server to help you diagnose the problem and find the failing part.

For quick problem determination when you are physically at the server, the server offers the following three-step guided path:

  • Illuminate the Fault LED on the front panel. 
  • Identify the fault in the light path diagnostics panel, as shown in the following figure.
  • If a DIMM is faulty, the LED next to it is illuminated.

The SN850 light path diagnostics panel is inside the server near the front panel, as shown in the following figure.


Figure 10. Location of SN850 light path diagnostics panel

To illuminate the light path diagnostics LEDs, power off the server, slide it out of the chassis, and press and hold the power button. The power button doubles as the light path diagnostics reminder button when the server is removed from the chassis.

The meanings of the LEDs in the light path diagnostics panel are listed in the following table.

Table 28. Light path diagnostic panel LEDs
LED Meaning
LIGHT PATH The light path diagnostics panel is operational.
SYSTEM  BOARD A system board error is detected.
NMI A non-maskable interrupt (NMI) occurred.
CPU MISMATCH The processors are mismatched.
TEMP An over-temperature condition occurred that was critical enough to shut down the server.
MEMORY A memory fault occurred. The corresponding DIMM error LEDs on the system board are also lit.
STORAGE BP 1 A hard disk drive backplane error has occurred.
M.2  A M.2 backplane error has occurred.

The front of the server also houses an information pull-out tab. 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.

Remote management

Lenovo XClarity Controller (XCC) is an all-new embedded management engine common in every ThinkSystem server. 

There are two ways to access the management processor:

  • Command-line interface. To access the CLI interface, use SSH to log in to the management processor.

  • Web-based interface. To access the web-based interface, point your browser to the IP address for the management processor. The new intuitive interface includes at-a-glance visualizations and simple access to common system actions.  The dashboard is shown in the following figure. 

Figure 11. Lenovo XClarity Controller dashboard

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

Virtual presence (remote control) and virtual media capability also come standard in the SN850. The remote control functions include the following:
