A customer’s storage environment is organized into four singledirector fabrics. The directors are MDS9509s with 64 switch ports in each. No more than 70% of available ports are in use.
The customer needs hosts in each fabric to access storage in the other three fabrics. It is acceptable for hosttostorage traffic to traverse up to one hop.
What is the least disruptive SAN solution that you should consider?

A.
Convert to core/edge single fabric, isolating all storage to the core director

B.
ISLs between adjacent directors to create a partial mesh

C.
ISLs between adjacent directors to create a partial mesh and enable trunking

D.
ISLs between all directors to create a full mesh
