The image is a diagram of before and after consolidation of NIC ports. It shows comparison of three network connections. The first diagam shows three hardware servers making three network connections through three physical network interface cards and ports, all at the same speed. The second diagram shows how virtualization consolidates the network connections. One hardware server running three zones uses three virtual network interface cards but only one physical network interface card and port. Each network connection can be tuned to a different speed according to the requirements of each zone.
