Guidelines And Limitations For Vsans - Cisco Nexus 5000 Series Configuration Manual

Configuring and Managing VSANs
VSAN Characteristic
VSANs are defined for larger environments (storage
service providers).
VSANs encompass the entire fabric.
The following figure shows the possible relationships between VSANs and zones. In VSAN 2, three zones
are defined: zone A, zone B, and zone C. Zone C overlaps both zone A and zone B as permitted by Fibre
Channel standards. In VSAN 7, two zones are defined: zone A and zone D. No zone crosses the VSAN
boundary. Zone A defined in VSAN 2 is different and separate from zone A defined in VSAN 7.

Guidelines and Limitations for VSANs

VSANs have the following configuration guidelines and limitations:
• VSAN ID—The VSAN ID identifies the VSAN as the default VSAN (VSAN 1), user-defined VSANs
• State—The administrative state of a VSAN can be configured to an active (default) or suspended state.
OL-27583-01
(VSAN 2 to 4093), and the isolated VSAN (VSAN 4094).
Once VSANs are created, they may exist in various conditions or states.
◦ The active state of a VSAN indicates that the VSAN is configured and enabled. By enabling a
VSAN, you activate the services for that VSAN.
