Virtualization technologies have been at the forefront of the planning and implementation efforts for many IT professionals. While the basic capabilities have been incorporated into a variety of earlier products, it was the introduction of server virtualization that helped optimize x86 servers and enabled IT departments to realize significant cost savings that catapulted virtualization to become common terminology among IT professionals and CXOs. This renewed interest in virtualization technologies led to its use for other platforms such as desktops, storage devices, and even applications themselves. In the center of these virtualization trends is the network infrastructure “highway” that ties together all of these new services. In this capacity the network plays a key role toward ensuring that the implementation of these virtualization technologies does not impact the high-quality user experience end users have come to expect.
