Purley 4U2S GPU Server Platform with a Single-Root Complex Design  High Memory / NVMe Storage & Intel® OCULink
Designed for GPUDirect RDMA Applications, AI, and Deep Neural Network Workloads.

Increased Total Expansion Capability from Its Previous Generation

A new design based on PNYSER48 series, PNYSRA4X series can commodate up to 10 double-width GPU boards and has an 11th slot to the rear of the chassis, allowing a single-width PCIe x16 card to be installed. This new design change is ideal for NVMe deployment or high speed networking like 100 Gigabit EDR Infiniband, 100 Gigabit Ethernet, or 100 Gigabit Intel Omni-Path fabric. Furthermore, an internal storage mezzanine slot (for SAS storage deployment without taking up PCIe slots) is also available for integrating device controller solutions



Single-Root Complex Design - Optimized for Deep Learning Applications

As a single-root complex GPU server, PNYSRA4X series deploys a set of two PLX® PEX8796 PCIe switch chips to provide direct connectivity between one single CPU and 10 GPU boards (PCIe x16 slots) and an high-speed network card (PCIe x16 slot). For Deep Learning applications, this design allows data exchanges and instruction signals to be assembled/dispatched more efficiently (between the CPU, the 10 GPU boards and the high-speed network card), both on the hardware level (single or multiple nodes) and in the Deep Learning framework. This also translates into better conservation of precious CPU compute resources (on the 2nd CPU) for faster workload processing (either on different threads apart from the 1st CPU or in collaboration with the 1st CPU).

IPMI 2.0 with Redfish Support

Featuring AMI MegaRAC® firmware, PNYSRA4X series offers support for IPMI 2.0 with iKVM and the DMTF Redfish management protocol. The MegaRAC® SP-X SoC (System-on-Chips) has an AMI generic, user-friendly Graphics User Interface (GUI) called the MegaRAC® GUI. It is designed to be easy to use. It has a low learning curve because it uses a standard Internet browser. You can expect to be up and running in less than five minutes.

Extend Your Scale with Intel® Xeon® Scalable

PNYSRA4X series is built around Intel Skylake CPU architecture - ‘Intel® Xeon® Scalable’. This new product family provides a wealth of new options in scalability - across compute, network and storage - to deliver solutions for a range of applications.


CPU Key Features

Intel® Xeon® Scalable CPU architecture brings improved features and functionality at both the host and fabric levels. These enable performance improvements - both natively on the chip and for future extensibility through compute, network and storage peripherals.
