General features Brocade adapters support the following general features for enhanced performance and connectivity in the SAN and Ethernet networks. I/O virtualization Brocade adapters support physical function (PF) based I/O virtualization to provide data isolation and sharing of the bandwidth resources. Depending on the adapter model or the operating mode (CNA, HBA, or NIC) assigned to Fabric Adapter ports), from one to eight functions can be supported per port on the PCI bus. These PFs can be seen as multiple adapters by the host operating system or hypervisor. Factory default PF configurations For each type of adapter, each port has a set base or default PF as follows: • For HBA models, each port has one Fibre Channel (FC) function. • For CNA models, each port has one FC function and one Ethernet function. 16 Brocade Adapters Installation and Reference Manual 53-1002144-01
