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-
