Optimized for Virtualization
Using multi-port cards in virtualized
environments critical to the application in order
to provide redundancy and data connectivity
for the workloads in the virtual machines. Due
to specific slot limitations and the need for
redundancy/data connectivity, it is usually
recommended virtualized servers use at least
six Gigabit ports to satisfy the I/O demands.

Virtual Machine Device queues
(VMware Direct Path)
(VMware Direct Path)
VMware Direct Path (SR-IOV) reduces I/O
overhead on the hypervisor in a virtualized
server by performing data sorting and uniting it
in the network silicon (this feature requires an
O/S that supports VMDq). This technology
makes use of multiple queues in the network
controller. As data packets enter the card, they
are sorted, and packets traveling to the same
destination/ virtual machine get grouped
together in a single queue. The packets are sent
to the hypervisor, which directs them to their
respective virtual machines. Taking the strain of
packet filtering and sorting from the hypervisor
improves overall CPU usage and throughput.

The AT-2973T Gigabit interface card provides
improved performance with the next-
generation (VMDq) technology, which includes
features such as loop back (inter-VM
communication), priority-weighted bandwidth
management, and doubling the number of data
queues per port from 4 to 8. It also supports
multicast and broadcast data on a virtualized
server.

Superior Functionality
The AT-2973T includes dedicated hardware and
processors to process frames at the highest
levels in the operating system for both transmit
and receive paths - advantageous for
virtualization applications.

The AT-2973T enables convergence of all the
networked communications possible in a server,
such as data (LAN), storage networks (iSCSI),
clustering, for example High Performance
Computing (HPC), or Inter-Process
Communications (IPC) by support of ROMA
over TCP.

More Bandwidth with PCI-
Express Interface
Express Interface
The PCI-Express (PCIe) design gives you the
maximum possible bandwidth and bus efficiency.
Other benefits are capability and low power
consumption.

Dual Port Copper Interfaces
Two copper port interfaces give you the
maximum protection against failure. If one link
goes down, the other keeps sending data to
prevent network down time.The two ports
can also be trunked to increase bandwidth in
server type applications.
