Functionality and Features: Broadcom NetXtreme II Network Adapter User Guide Back to Contents Page Functionality and Features: Broadcom NetXtreme II Network Adapter User Guide Functional Description Features Functional Description The Broadcom NetXtreme II adapter is a new class of Gigabit Ethernet (GbE) and 10 GbE converged network interface controller (C-NIC) that can simultaneously perform accelerated data networking and storage networking on a standard Ethernet network. The C-NIC offers acceleration for all popular protocols used in the data center, such as: TCP Offload Engine (TOE) for accelerating TCP over 1 GbE and 10 GbE Internet Small Computer Systems Interface (iSCSI) offload for accelerating network storage access featuring centralized boot functionality (iSCSI boot) Fibre Channel over Ethernet (FCoE) offload and acceleration for fibre channel block storage NOTE: Separate licences are required for all offloading technologies. Enterprise networks that use multiple protocols and multiple network fabrics benefit from the C-NICs ability to combine data communications, storage, and clustering over a single Ethernet fabric by boosting server CPU processing performance and memory utilization while alleviating I/O bottlenecks. The Broadcom NetXtreme II adapter includes a 10/100/1000-Mbps or 10-Gbps Ethernet MAC with both half-duplex and fullduplex capability and a 10/100/1000-Mbps or 10-Gbps PHY. The transceiver is fully compatible with the IEEE 802.3 standard for auto-negotiation of speed. Using the Broadcom teaming software, you can split your network into virtual LANs (VLANs) as well as group multiple network adapters together into teams to provide network load balancing and fault tolerance functionality. See Configuring Teaming and Broadcom Gigabit Ethernet Teaming Services for detailed information about teaming. See Virtual LANs, for a description of VLANs. See Configuring Teaming for instructions on configuring teaming and creating VLANs on Windows operating systems. Features The following is a list of the Broadcom NetXtreme II adapter features. Some features may not be available on all adapters.
