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 vir tual machines. Due
to specific slot limitations and the need for
redundancy/data connectivity, it is usually
recommended virtualized servers use at least
six Gigabit por ts to satisfy the I/O demands.
Virtual Machine Device Queues
(VMware Direct Path)
VMware Direct Path (SR-IOV) reduces I/O
overhead on the hypervisor in a virtualized
server by performing data sor ting and uniting it
in the network silicon (this feature requires an
O/S that suppor ts 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-2973SX Gigabit interface card provides
improved performance with the nextgeneration (VMDq) technology, which includes
features such as loop back (inter-VM
communication), priority-weighted bandwidth
management, and doubling the number of data
queues per por t from 4 to 8. It also suppor ts
multicast and broadcast data on a vir tualized
server.
Superior Functionality
The AT-2973SX 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-2973SX 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 suppor t of ROMA
over TCP.
More Bandwidth with PCIExpress Interface
The PCI-Express (PCIe) design gives you the
maximum possible bandwidth and bus efficiency.
Other benefits are capability and low power
consumption.
High Reliability
The AT-2973SX Gigabit interface card comes
with a comprehensive Microsoft Windows
utility that performs detailed tests, diagnostics
and analysis.
Advanced Manageability
The priority queuing offered by AT-2973SX can
help you set-up your network based on your
own needs. The comprehensive diagnostics and
configuration software suite provides system
adminstrators and engineers with a profound
tool to analyze the interface card to check
specific data.
Dual Port Fiber Interfaces
Two fiber 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 por ts
can also be trunked to increase bandwidth in
server type applications.
