The HPE Ethernet 10Gb 2-port 562 Adapters deliver high performance and low latency for Ethernet traffic to and from the server with minimal CPU resources required. Processing of I&O packets on the adapter frees up CPU to do other more important tasks. For environments such as TelcoNFV- high-performance computing and ecommerce that deal with large volumes of small packet traffic- these adapters accelerate small packet processing by bypassing processing in the host OS kernel. Network processor Intel X550. Bus type PCIe 3 x4. Form factor PCIe Card. Power 11.80W typical- 12.70W maximum.
