The above SAN is a single fabric, resilient design. To deploy a dual fabric, resilient SAN based upon this architecture, the following SAN would be built

Redundancy builds in the ability to allow for SAN management to take place on one SAN while the other SAN stays in operation. For a site where high availability is mandatory and where significant down time cannot be tolerated this design approach is the most prudent.
•When designing a fabric solution, consider using two redundant fabrics to provide the maximum flexibility in terms of SAN downtime and maintenance. This solution will allow for:
