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

The SN850 server is supported in the Flex System chassis as listed in the following table.

Table 13. Chassis support

Up to seven SN850 servers can be installed in the chassis; however, the actual number that can be installed in a chassis depends on the following factors:

• TDP power rating for the processors that are installed in the SN850
• Number of power supplies that are installed in the chassis
• Capacity of the installed power supplies (2100 W or 2500 W)
• Chassis power redundancy policy that is used (N+1 or N+N)
• Node throttling is allowed

The following table provides guidelines about what number of SN850 servers can be installed. For more information, use Lenovo Capacity Planner, which is found at the following web page:
https://datacentersupport.lenovo.com/us/en/products/solutions-and-software/software/lenovo-capacity-planner/solutions/ht504651

The following color coding was used In the table:

• Green = No restriction on the number of SN850 servers that can be installed
• Yellow = Some bays must be left empty in the chassis

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).

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.

* All Gold 5000-level processors, except the 5122, support 2400 MHz memory speeds and have one AVX-512 512-bit FMA units. The 5122 processor supports 2666 MHz and has two FMA units
** L3 cache is 1.375 MB per core except with the processor indicated with ** where the cache size is larger
† Only available as a special order. Please contact your Lenovo representative for details.

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.

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.

Storage backplane kits, RAID and M.2 upgrades are listed below.  

Supported drives are listed in the Internal drive options section. 

In addition to the optional M.2 RAID-1 enabled adapter, the SN850 supports 3 different RAID controllers as shown in the table below.

Both the 530-4i and 930-4i replace the onboard SATA controller in the server and support high-performance RAID to the four internal 2.5-inch drive bays.

The following figure shows the ThinkSystem RAID 530-4i adapter for the SN850 blade server. Note that the plastic frame in the lower right of the adapter is part of the mechanism that attaches the adapter to the server; this adapter does not support a supercapacitor.

Figure 5. ThinkSystem RAID 530-4i 

The following tables list the hard disk drive and solid-state drive options for the internal disk storage of the server.

The server supports booting from an operating system or hypervisor installed on an M.2 solid-state drive. See the Internal storage section for details and the list of available options. Preloaded M.2 drives can be configured as described in the Operating system support section.

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

The server does not support an internal optical drive, however, you can connect an external USB optical drive. Alternatively, use the remote media feature of the XClarity Controller and the Chassis Management Module.

The server supports the external USB optical drive listed in the following table.

The drive is based on the Lenovo Slim DVD Burner DB65 drive and supports the following formats: DVD-RAM, DVD-RW, DVD+RW, DVD+R, DVD-R, DVD-ROM, DVD-R DL, CD-RW, CD-R, CD-ROM.

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.

The location of the fabric connector is shown below.

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.

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.

For more information about supported switches, see the Flex System Interoperability Guide, which is available at this web page:
http://lenovopress.com/fsig

The following figure shows the location of the I/O module bays in the Flex System Enterprise Chassis.

Figure 8. Location of the I/O module bays in the Flex System Enterprise Chassis

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.  

FCoE and iSCSI support: ThinkSystem server adapters do not support Features on Demand, so the CN4052S and CN4054S 2-port 10Gb basic adapters cannot be upgraded to FCoE support. If you need FCoE or iSCSI support use the 01CV780 or 01CV790 adapters.

For more details about these adapters, see the Lenovo Press product guides in the Network adapters category: https://lenovopress.com/servers/blades/nic

For more information about adapter-to-switch compatibility, see the Flex System Interoperability Guide:
http://lenovopress.com/fsig

The following table lists storage Host Bus Adapters (HBAs) that are supported by the SN850. Storage HBAs are supported in all slots, however for CTO orders, the HBAs are installed only in slots 2 and 4.

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.

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

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.

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 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 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

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.

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

• Remotely viewing video with graphics resolutions up to 1600x1200 at 75 Hz with up to 32 bits per pixel, regardless of the system state

Lenovo XClarity Energy Manager

Lenovo XClarity Energy Manager (LXEM) is an agent-less, web-based console that provides power management for ThinkServer, System x and ThinkSystem servers. It enables server density and data center capacity to be increased through the use of power capping.

LXEM is a licensed product. A single-node LXEM license is included with the XClarity Controller Enterprise (XCC Enterprise) version. Because the Enterprise version of XCC is standard in the SN850, a license for XClarity Energy Manager is included.  For more information on LXEM, please see the User Guide: http://datacentersupport.lenovo.com/us/en/downloads/ds101160

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 SN850. The software can be downloaded and used at no charge to discover and monitor the SN850 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.

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.
