What is zoning in storage?

Zoning is a fabric-based service in a storage area network (SAN) that groups together hosts and storage nodes that require communication. The essential requirement for performing zoning is that the nodes can communicate only if they are members of the same zone.

What is zoning and types of zoning in storage?

Zoning in a SAN is a used to segment traffic between targets and initiators, or less formally workstations and storage. Zoning is generally used for security or performance benefits. Zoning can be set up through software, referred to as Soft Zoning or it can be set up through hardware, referred to as Hard Zoning.

What is LUN zoning?

LUN zoning is a method of configuring storage area network (SAN) fabric to match logical unit numbers (LUNs ) so that end device access is limited to the appropriate storage devices. Zoning can be used to isolate a single server to a specific logical unit or associate a group of servers with a logical unit.

What is LUN masking in storage?

LUN Masking is a level of security that makes a LUN available to only selected hosts and unavailable to all others. This kind of security is done on the SAN level and is based on the host HBA, i.e. you can give access of specific LUN on the SAN to specific host with specific HBA.
