The IBM Flex System™ CN4054 and CN4054R 10Gb Virtual Fabric Adapters are 4-port 10Gb converged network adapters (CNA) for Intel processor-based compute nodes that support Ethernet, iSCSI, and FCoE. The adapters support up to eight virtual NIC (vNIC) devices, where each physical 10 GbE port can be divided into four virtual ports with flexible bandwidth allocation. The CN4054 Virtual Fabric Adapter Upgrade adds FCoE and iSCSI hardware initiator functionality to either adapter. The CN4054R adds support for compute nodes with the Intel Xeon E5-2600 v2 processors. The IBM Flex System EN4054 4-port 10Gb Ethernet Adapter is based on similar hardware but simply operates as a straight 4-port 10 GbE adapter.
