ABC.com’s storage environment is organized into four single-director fabrics, one each for the
Engineering, Marketing, Sales, and Finance divisions. The directors are MDS-9509s populated
with several switch modules providing 64 switch ports in each director.
Hosts and storage frames connect to each fabric with no more than 70% of available ports in use.
There is complete isolation between the four SAN islands.
With the planned rollout of new cross-functional applications, the customer needs hosts in each
fabric to access storage in the other three fabrics. It is acceptable for host-to-storage traffic to
traverse up to two hops.
What is the most efficient and least disruptive SAN solution that would meet this need?

1. Price
2. Scalability
3. Ease of maintenance
4. Minimal operational disruption
Which solution would best meet the customer’s requirements?
