Configuring and Managing VSANs

You can achieve higher security and greater stability in Fibre Channel fabrics by using virtual SANs 
(VSANs) on Cisco MDS 9000 Family switches and Cisco Nexus 5000 Series switches. VSANs provide 
isolation among devices that are physically connected to the same fabric. With VSANs you can create 
multiple logical SANs over a common physical infrastructure. Each VSAN can contain up to 239 
switches and has an independent address space that allows identical Fibre Channel IDs (FC IDs) to be 
used simultaneously in different VSANs. This chapter includes the following sections:
