16 Brocade Adapters Installation and Reference Manual53-1002144-01Adapter features1 Storage systemsUsing Brocade HBAs you can connect a server (host system) to a Fibre Channel SAN in a switchedfabric and point-to-point topology or directly to a storage array in a point-to-point topology. Refer tothe latest Brocade interoperability matrices for a list of supported server models on Brocade’swebsite at www.brocade.com/adapters.Adapter featuresThis section describes the features associated with all models of the following types of Brocadeadapters:• Fabric Adapters - Refer to the following subsections depending on the port mode and SFPconfigurations:- “General features” on page 16.- “FCoE features” on page 20, for ports configured in CNA mode.- “Data Center Bridging and Ethernet features” on page 22, for ports configured in CNA orNIC modes.- “HBA features” on page 27, for ports configured in HBA mode.• CNAs- Refer to the following subsections:- “General features” on page 16.- “FCoE features” on page 20.- “Data Center Bridging and Ethernet features” on page 22.• HBAs - Refer to the following subsections:- “General features” on page 16.- “HBA features” on page 27.General featuresBrocade adapters support the following general features for enhanced performance andconnectivity in the SAN and Ethernet networks.I/O virtualizationBrocade adapters support physical function (PF) based I/O virtualization to provide data isolationand 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 supportedper port on the PCI bus. These PFs can be seen as multiple adapters by the host operating systemor hypervisor.Factory default PF configurationsFor 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.
