To enable fabric growth far beyond the number of ports on a single switch, QLogic has developed easy-to-use software features that allow multiple switches to be linked together. These features, included at no extra charge with every SANbox switch product, automatically configure fabrics to thousands of end ports without performance degradation.

From simple cascaded topologies to an exclusive Multistage™ "cross-connect" architecture, QLogic provides more scalability options than any other vendor. Depending on the customer's individual performance, resiliency and cost needs, any mixture of the following multi-switch interconnects can be implemented.
