Most enterprise virtualization deployments make use of a robust shared storage infrastructure.  A high-performance SAN allows multiple hypervisors to access virtual machine disks and is the foundation for amazing virtualization benefits such as VMware vMotion and HA.  There are other benefits, too.

Virtualization management tasks such as cloning existing virtual machines or deploying new ones from templates often involve slinging around multi-gigabyte chunks of data.  It’s preferable to move or copy data on the SAN instead of the LAN because it can be faster, but more importantly, doing so reduces impact to other services that rely on the LAN.
