It is an OCP 3.0 card with two SFP28 ports that auto-negotiate 1, 10 and 25Gb, and a PCIe 4x8 connection. HPE rates power at 13 W typical and 18.4 W maximum. The spare, P42933-001, is named by HPE as an OCP3 2-port 10/25G SFP28 MCX631432AS card.
HPE lists UEFI and legacy BIOS PXE boot, wake-on-LAN, iSCSI remote boot in UEFI mode, IPv4 and IPv6, receive side scaling, VMware NetQueue and Microsoft VMQ, and tunnel offload for VXLAN, NVGRE and GENEVE. RDMA is RoCEv1 and RoCEv2. It also lists DPDK, a hardware root of trust, secure boot, authenticated updates, audit log and sanitization.
