What is Zoning?

Zoning is a fabric-based service in a storage area network (SAN) which require network communication to group hosts and storage nodes together. The basic requirement for performing zonings is that the nodes can communicate only if they are members of the same zone. The nodes can also be members of multiple zones, flexibility while using the method. It used to allocate resources in a SAN to load balance the device connected to the network. This provides permission to network administrators to separate a SAN into different units and allocate storage to the required specified unit.

It also protects the system from malicious hackers, virus threats, and data corruption as devices in the specified zones do not communicate outside the zone through their ports unless permitted. Zoning's also prevents undesired host-to-host communication and fabric-wide registered change notification disruption and stops a host from gaining unauthorized access to storage assets. Hosting is managed by a fabric-name server and when a storage node or switch goes offline, it notifies end-devices of events in fabrics. The most common zones are port zones, mixed zones, and worldwide name zones.
