Why do fiber optic switches use zones
In, Fibre Channel zoning is the partitioning of a into smaller subsets to restrict interference, add security, and to simplify management. While a makes available several devices and/or ports to a single device, each system connected to the SAN should only be allowed access to a controlled subset of these devices/p. Similar to the VLAN function of an Ethernet switch, the zoning function of a Fibre Channel switch allows users to isolate links, thereby reducing fault domains and link contention between hosts or applications. Zoning is a connection isolation technique that is required when connecting hosts with the storage system over Fibre Channel SAN.
