HPS-621D4A

Series: HPS

Manufactured byAvalue
HPS-621D4A Front

The Avalue HPS-621D4A is a 19" 4U rackmount workstation built around the Avalue HPM-621DE dual-socket server board for two 1st/2nd Generation Intel® Xeon® Scalable processors (max. TDP up to 150W each) with the Intel® C621 chipset, designed as a high-core-count, GPU/accelerator-ready node for HPC and edge servers. With 12 x DDR4 2933/2666/2400/2133MHz RDIMM/LRDIMM up to 1.5TB, a 1300W ATX PSU and IPMI 2.0 via an ASPEED AST2500 BMC, it packages two-socket Xeon Scalable performance into a 430 x 174.8 x 528 mm chassis. It provides 4 x PCIe Gen3 x16, 2 x PCIe Gen3 x8 and a PCI 3.0 slot, an M.2 NVMe, 3 x front-accessible 2.5" bays, quad Intel I210AT 1GbE, USB 3.2 Gen1 and VGA, running Windows 10 IoT, Windows Server 2016/2019 or Ubuntu 18.04 LTS or later.
