  • Intel Speed Select Technology provides improvements in server utilization and guaranteed per-core performance service levels with more granular control over processor performance.
  • Intel Deep Learning Boost (Vector Neural Network Instruction set or VNNI) is designed to deliver significant, more efficient Deep Learning (Inference) acceleration for high-performance Artificial Intelligence (AI) 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. Up to 3 TB of memory capacity using 64 GB RDIMMs. Higher memory capacity by using Persistent Memory.
  • Supports 2933 MHz and 2666 MHz memory DIMMs
  • Supports the new Intel Optane DC Persistent Memory; up to 24 Data Center Persistent Memory Modules (DCPMMs) can be installed in conjunction with regular memory DIMMs. DCPMMs are up to 512 GB each, for a total of up to 12 TB of Persistent Memory.
  • 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 up to 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, 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) management processor 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.
  • 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.
