About SDV

As of Cisco SAN-OS Release 3.1(2) and NX-OS Release 4.1(1a), 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
