About SDV

As of Cisco SAN-OS Release 3.1(2) and later, you can use Cisco SDV to create virtual devices that
represent physical end-devices. Virtualization of SAN devices accelerates swapout or failover to a
replacement disk array, and it also minimizes downtime when replacing host bus adapters (HBAs) or
when re-hosting an application on a different server.
SAN devices that are virtualized can be either initiators or targets. You can virtualize targets to create a
virtual target, and also virtualize initiators to create a virtual initiator. Such configurations do not
distinguish between virtual initiators and virtual targets (see
