Information About Storage VDC

You use a virtual device context (VDC) to separate LAN and SAN traffic on the same switch. A VDC allows
you to maintain one physical infrastructure but separate logical data paths.
To achieve this configuration, you must perform the following tasks:
• Create a dedicated storage VDC.
• Allocate a VLAN range for FCoE.
• Optionally, share physical ports between the storage VDC and one other VDC.
For shared physical ports, the VDC where the ports are shared includes a VF Ethernet port that corresponds
to the shared port. You cannot modify some details of that port because it must match the underlying shared
physical port. If you move the source port to another VDC or delete the VDC, the shared ports are deleted
and you must reconfigure them.
Note If the Ethernet VDC restarts or is suspended, any shared Ethernet ports are shut down in the corresponding
VDC. These ports come up automatically once the Ethernet VDC is operational.
