Built for HPE BladeSystem c-Class, the 700748-B21 is a two-port 10GbE mezzanine adapter based on a Cavium 57810S network processor with integrated MAC and PHY. It is a Type A mezzanine card, so it works in both Type A and Type B mezzanine slots, and it uses a PCI Express 2.0 (Gen 2) x8 connection to the blade.
Each of the two ports is rated at 20 Gb/s bi-directional, which gives 40 Gb/s of aggregate theoretical bandwidth per adapter. Behind a Virtual Connect Flex-10 module every 10Gb port can be split into four physical NICs, with speeds set from 100 Mb/s to 10 Gb/s in 100 Mb/s steps, and switch-independent NPAR partitioning is available too. Without a Flex-10 device it links at 1000 or 10000 Mbps, and against a 1Gb Ethernet interconnect it links at 1000 Mbps only.
The adapter offloads iSCSI and FCoE storage processing, which makes it a full converged network adapter. It also supports SR-IOV, VXLAN and NVGRE tunnel offload, jumbo frames up to 9,000 bytes, PXE boot, receive-side scaling and IEEE 1588 time sync; DPDK and Virtual Connect cannot be used at the same time. It needs at least 2 GB of server memory, draws under 12 W and operates from 0 to 55 degrees Celsius.
Listed host blades are the ProLiant BL460c Gen9, BL660c Gen9, WS460c Gen9 and BL460c Gen10. The spare for this option is 701530-001.
More adapters are under HPE interface cards.
