Since we have a total of 4 fibre switches, each storage array controller will connect to a different switch, providing fault
tolerance down to the storage controller. The 16 arrays are divided in half so that 8 arrays will use 2 switches and the other
8 arrays will use the 2 other switches. HBAs are also divided for redundancy, with HBAs 1-5 and 11 using 2 switches and
6-10 using 2 switches also.
