HPM-SRSDE
Series: HPM
The Avalue HPM-SRSDE is a dual-socket proprietary-form-factor server board built on twin Intel LGA4677 sockets for 4th Generation Intel® Xeon® Scalable processors (max. TDP up to 270W each) with the Intel® C741 chipset, designed as a high-core-count, expansion-rich x86 platform for HPC and edge data-center nodes. With 12 x DDR5 4800/4400MHz RDIMM up to 3TB, onboard TPM 2.0 and IPMI 2.0 via an ASPEED AST2600 BMC, it delivers two-socket Xeon Scalable performance on a 12" x 16.452" board. It provides 7 x PCIe Gen5 x16 slots, an M.2 M-Key PCIe 5.0 x4 NVMe, 5 x SATA III (RAID 0/1/5/10), 3 x Slim SAS 8i, triple Intel Ethernet (I210AT 1GbE, I226-LM 2.5GbE, X550AT2 dual 10GbE), and USB 3.2 Gen1/USB 2.0, running Windows 10 IoT / Windows Server IoT 2019/2022, Ubuntu or RHEL.
