Functional Descriptions
The AT-2973SX and AT-2973T Broadcom NetXtreme II adapters are in a
new class of Gigabit Ethernet (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, 2.5 GbE,
and 10 GbE
 Internet Small Computer Systems Interface (iSCSI) offload for
accelerating network storage access featuring centralized boot
functionality (iSCSI boot)
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 AT-2973SX and AT-2973T adapters include a 10/100/1000-Mbps
Ethernet MAC with both half-duplex and full-duplex capability and a 10/
100/1000-Mbps PHY. The transceiver is fully compatible with the IEEE
802.3 standard for auto-negotiation of speed.
As part of the company’s green range, both products are engineered to
reduce power consumption. They incorporate centralized power
management features that automatically place idle circuitry into a lower
power mode to save energy.
This section provides functional descriptions of the AT-2973SX and AT-
2973T adapters.
