Virtual Fabrics overview
Virtual Fabrics is an architecture to virtualize hardware boundaries. Traditionally, SAN design and
management is done at the granularity of a physical switch. The Virtual Fabrics feature allows SAN
design and management to be done at the granularity of a port.
Virtual Fabrics is a suite of related features that can be customized based on your needs. The
Virtual Fabrics suite consists of the following specific features:
•Logical switch
•Logical fabric
•Device sharing
