Configuring a Virtual Device

A virtual device is identified by an alphanumeric name of up to 32 characters and defines all the real
devices (one primary and one or more secondary) that it represents. Upon the successful creation of a
virtual device, the virtual device name is internally registered as the device alias name with the device
alias database; the pWWN is automatically assigned by the system using Cisco Organizational Unique
Identifier (OUI). A virtual device appears as a real, physical device. You can enumerate up to 128 devices
for a virtual device. There is a limit of 4095 on the number of virtual devices that you can create in a
single VSAN.
As of Cisco MDS SAN-OS Release 3.1(2) and NX-OS Release 4.1(1a), SDV supports up to 1024 virtual

devices per VSAN.
