Functional Description
The Marvell 57xx and 57xxx adapter is a new class of gigabit Ethernet (GbE) and
10GbE 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 popular protocols used in the
data center, such as:
 TCP offload engine (TOE) for accelerating TCP over 1GbE and 10GbE (on
Windows Server OSs that support TOE)
 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
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 Marvell 57xx and 57xxx adapters include a 10Mbps, 100Mbps, 1000Mbps, or
10Gbps Ethernet MAC with both half-duplex and full-duplex capability and a
10Mbps, 100Mbps, 1000Mbps, or 10Gbps physical layer (PHY). The transceiver
is fully compatible with the IEEE 802.3 standard for auto-negotiation of speed.
NOTE
Not all adapters support each listed protocol. Refer to the specific
product data sheet for protocol support.
