FIGURE 2. Two Core Switch, Two ISL, Star Design.
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
FIGURE 3. Dual Fabric Design, Hosts and Storage connection to Two Independent Fabrics:
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:
No connection!
Hosts and
Storage
Dual connections
