1 Introduction
1.1 General Specifications
The 2U EOS server revolutionizes the capabilities of homogenous systems containing closely coupled processors, NVMe solid-state storage,
high-speed networking and accelerator co-processing elements such as GP-GPUs and FPGAs. The 2U EOS contains two of the newest Intel
Scalable Processors and provides the widest BIOS compatibility with dense storage and accelerator expansion systems. This allows the highly
integrated server to stand alone or form the core CPU and memory resources for a scale-out, rack level, expandable solution. The EOS server
features two storage and I/O configurations providing up to six PCIe 3.0 x16 half-height slots or 24 U.2 NVMe drives. The server supports up to
4TB of memory and a resource expanded BIOS for scale-out device enumeration and large memory mapped I/O used for GP-GPUs and
accelerators
