Refer to the exhibit. You are designing a new SAN. The existing SAN uses eight 32-port 2-Gbps Fibre Channel switches. Two of the switches are deployed as core switches, and the remaining six switches are deployed as edge switches. Each edge switch has two ISLs to each of the two core switches. The disk array has twelve 2-Gbps Fibre Channel ports. Each of the 84 servers has a dual-port 1-Gbps Fibre Channel HBA.
