View the refurbished HP NC512m Dual Port 10GbE Multifunction BL-c Adapter 440910-B21 448515-001 Quickspecs here
The refurbished NC512m is a dual port 10 Gigabit Ethernet network server adapter for ProLiant c-Class BladeSystem. It offers the highest bandwidth available in a ProLiant Ethernet c-Class adapter. In addition to standard layer 2 10 Gigabit Ethernet communication, this Multifunction server adapter provides stateful TCP offloading (TCP/IP offload engine or TOE) for Linux. The refurbished NC512m also ships with support for stateless TCP offloading (LSO and TCP checksum), 802.1p QoS, 8K jumbo frames, interrupt coalescence, and more. One NC512m adapter is supported per ProLiant c-Class server in mezzanine slot 2 or 3 (full height servers) and slot 2 (half height servers) providing up to thirty-two (32) 10 Gigabit Ethernet adapter ports per c7000 enclosure and sixteen (16) per c3000 enclosure.

For overall improved system response, the NC512m supports standard TCP/IP stateless offloading techniques including:
- TCP/IP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the network adapter.- Large send offload (LSO), also known as TCP segmentation offload (TSO), allows TCP segmentation to be handled by the adapter rather than the CPU
