Tuning Practices for Virtual Networks

As you saw with storage virtualization, good practices in a physical network architecture work just as well in a virtual network environment. Physical networks use switches to isolate traffic for performance and security considerations. Those same practices carry through into virtual networks. Virtual switches tied to physical NICs can continue the physical segmentation into the virtual networking. A virtual network can be made just as complex and sophisticated as a physical network. One advantage that virtual networking maintains from a cost and maintenance standpoint is the lack of cabling, or at least a tremendous reduction.

As you saw with memory and CPU virtualization, network virtualization is very ...
