You are architecting a redundant SAN which will include 100 hosts with dual HBAs,50 hosts with
Quad HBAs, and storage arrays which have a total of 48 ports. The SAN implements redundant
Fabrics and redundant ISLs. A 128 port director is ten times as expensive as a 16 port switch.
Focusing on management, cost, performance, and future expansion, which solution is the most
effective?

A.
4 directories

B.
32 switches in a mesh configuration

C.
2 directors and 16 switches in a mesh configuration

D.
2 directors and 16 switches in a core edge configuration
