Take Advantage of Virtual Switching Technologies from Intel

Various technologies that Intel has developed (or helped develop)

help reduce the software overhead associated with virtual switching.

Some of the more important of these include the following:

•Virtual Machine Device Queues (VMDq)

offloads part of the

burden of processing network traffic from the hypervisor to

the network controller, enabling 10Gb connections to deliver

near-native throughput.

•Single Root I/O Virtualization (SR-IOV)

is an industry

specification supported by Intel that allows multiple VMs to

access network hardware directly, helping dramatically improve

virtualized performance and direct assignment scalability.

•Intel® Virtualization Technology for Directed I/O (Intel® VT-d)

allows a VM to have direct, exclusive access to an I/O device

and system memory, helping to provide increased memory

protection through isolation.

Ethernet 10 Gigabit server adapters help forward-looking IT

organizations continue expanding services while contributing

to a healthier bottom line.
