OSS-SDS-3U-4A 7
2 Product Information
The Gen 4 PCIe SDS-3U-4a contains options for Dual or Single-Socket AMD EPYC™ 7003 Series Processors and provides a feature packed server
platform for GPU or FPGA accelerated computing, U.2/U.3 NVMe storage and the most native PCIe Gen 4 x16 slots available on the market. This
functionality is delivered in a size efficient edge ready rugged chassis with 3U height and 20” depth. This allows the edge optimized server to
stand alone as a hyperconverged PCIe Gen 4 server or form the core CPU and memory resources for a scale-out, rack level, expandable or
composable solution in the shallowest available racks. The SDS-3U-4a features up to 7 PCIe Gen 4 x16 slots, and 16 SATA/SAS/NVMe drives. The
server supports up to 2TB of memory per CPU socket and a resource expanded BIOS for scale-out device enumeration and large memory
mapped I/O used for GPUs and accelerators.
