The EOS-2U-4a contains an AMD EPYC™ 7002 Series Processor 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-2U-4a features six PCIe 4.0 x16 half-height slots and 1 PCIe 3.0 x16 half height slot. The EOS-2U-4a provides options for 7x add-in cards or 24x U.2 or U.3 drives. The server supports up to 2TB of memory and a resource expanded BIOS for scale-out device enumeration and large memory mapped I/O used for GP-GPUs and accelerators.
