The CN4054 and CN4054R 10Gb Virtual Fabric Adapters also support the following additional features:

Operates either as a 4-port 1/10 Gb Ethernet adapter or supports up to 16 vNICs.



Supports Unversal Fabric Port (UFP)



In virtual NIC (vNIC) mode, it supports:



Virtual port bandwidth allocation in 100 Mbps increments.



Up to 16 virtual ports per adapter (four per port).



With the CN4054 Virtual Fabric Adapter Upgrade, 90Y3558, four of the 16 vNICs (one per port)



support iSCSI or FCoE.

Supports for two vNIC modes: IBM® Virtual Fabric Mode and Switch Independent Mode



Wake On LAN support.



With the CN4054 Virtual Fabric Adapter Upgrade, 90Y3558, the adapter adds FCoE and iSCSI



hardware initiator support.

iSCSI support is implemented as a full offload and presents an iSCSI adapter to the operating



system.

TCP Offload Engine (TOE) support with Windows Server 2003, 2008, and 2008 R2 (TCP Chimney)



and Linux.

Connection and its state are passed to the TCP offload engine.



Data transmit and receive is handled by adapter.



Supported with iSCSI.
