What is zoning and masking?

LUN masking takes place at either the host bus adapter (HBA) or storage controller, and restricts the hosts’ ability to access specific LUNs. LUN zoning generally takes place on storage-area network (SAN) switches and compartmentalises the SAN fabric, grouping hosts and storage arrays into zones.

What are different types of zoning in SAN?

There are two distinct methods of zoning that can be applied to a SAN: World Wide Name zoning and port zoning. WWN zoning groups a number of WWNs in a zone and allows them to communicate with each other. The switch port that each device is connected to is irrelevant when WWN zoning is configured.
