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. Virtual Fabrics 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
