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 (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
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-2973T 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-2973T 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 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.
