PCIe Gen 4 3U Short Depth Intel Server (SDS-3U-4i)

The 20” deep SDS-3U-4i contains two Intel Scalable Processors and provides a feature packed server platform for GPU or FPGA accelerated computing, NVMe storage PCIe Gen 4 expansion slots.

Weight: 45 lb

The 20” deep SDS-3U-4i contains two Intel Scalable Processors and provides a feature packed server platform for GPU or FPGA accelerated computing, NVMe storage PCIe Gen 4 expansion slots. This functionality is delivered in a size efficient, edge ready rugged chassis with 3U height and 20” depth. This highly integrated server can operate 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-4U-4i features six PCIe Gen 4 x16 full-height slots (four of which are double-width), one PCIe Gen 4 x8 full-height slot and options for 8 or 16 SATA/SAS/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 GPUs and accelerators.
