The HP 552M adapter support for NIC teaming helps IT administrators increase network fault tolerance and
improve workload balance. These capabilities optimize availability, improve performance and help reduce
costs.
For overall improved system response, the HP 552M adapter 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.
TCP/IP Offload Engine (TOE) moves the processing of data in the TCP protocol stack from the server
CPU to the network card, freeing CPU cycles for other duties.
Single-Root I/O Virtualization (SR-IOV) provides a mechanism to bypass the host system hypervisor in
virtual environments providing near metal performance and server efficiency. SR-IOV provides mechanism
to create multiple Virtual Functions (VFs) to share single PCIe resources. The adapter supports SR-IOV, and
requires Server BIOS support, controller firmware, and OS support.
