The SN850 offers the following features to boost performance, improve scalability, save energy.
Scalability and performance:
- Up to seven SN850 servers can be installed in a single 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.
- Each processor has six memory channels with two DIMMs per channel running at up to 2666 MHz.
- Optional support for high-performance PCIe-attached NVMe Flash Storage solid-state drives (SSDs) can significantly improve I/O performance.
- Support for 25/50 Gb Ethernet, 16 Gb Fibre Channel, and FDR InfiniBand.
- 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.
