HPE InfiniBand HDR100/Ethernet 100Gb 2-port QSFP56 PCIe4 x16 MCX653106A-ECAT Adapter

P23666-B21 is the two-port HPE InfiniBand HDR100/Ethernet 100Gb QSFP56 adapter on a PCIe 4.0 x16 low-profile card, built on the Mellanox ConnectX-6 VPI chip (MCX653106A-ECAT). HPE gives P24752-001 as its replacement part number.

HPE describes the dual-port card as able to run as two HDR100 InfiniBand ports, two 100 Gbps Ethernet ports, or one of each. On ProLiant Gen10 Plus servers it delivers 200G of Ethernet in total (2 x 100G). HPE also lists the ConnectX-6 two-port HDR100 adapter as P23666-H21, the version for XL servers, and P06251-H21, the PCIe 3.0 model for Gen10 servers; HPE says a different part number must be ordered for each server generation.

HPE rates the two-port HDR100 card at 17.7 W typical and 22.4 W maximum with passive cables, and 28.5 W maximum with active optical cables, over 0 to 55 degrees C and 5% to 95% non-condensing humidity. The box holds the card with tall and short brackets and a quick install card.

Feature list from HPE: SR-IOV with up to 256 virtual functions and 16 physical functions per port, RoCE, VXLAN and NVGRE offload, NVMe over Fabrics offloads, IEEE 1588v2 time sync, jumbo frames up to a 9.6 KB MTU, PXE boot over InfiniBand, and IBTA 1.3 compliance. HPE adds that the QSFP ports do not support splitter cables when used as Ethernet, and that Ethernet cables and transceivers must be Power Class 4 or below (3.5 W maximum).

HPE lists the P23666-B21 option for the DL385, DL325, DL365, DL345, DL360 and DL380 Gen10 Plus servers. Related adapters: HPE interface and network cards and Mellanox MCX631102AS-ADAT 10/25Gb 2-port SFP28 adapter for HPE P42044-B21.
