Vendors find many ways to make storage virtualization work

ByDeni Connor, Network World 10/1/07

This approach enables controller-based virtualization products to attach to standard Fibre Channel storage arrays and look at their data in the same manner as their own internal hard disks.

In array-based virtualization such as that with the HP Enterprise Virtual Array, EMC Symmetrix DMX or 3Par, virtualization is enabled by the creation of virtual LUNs (logical attachments between server and storage.) While they do not provide the virtualization nirvana ? that of working with heterogeneous storage devices ? they do offer flexibility in managing LUNs.
