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 masking in VMware?
LUN masking is a process wherein you would mask LUNs, or make those LUNs inaccessible to the VMware ESXi hosts. This needs to be performed on individual ESXi hosts using something called claimrules.
What is zoning and masking in storage?
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.
How do you do zoning?
Zoning steps:-
- Zoning steps:-
- Identify the WWPN of Server HBA and Storage HBA.
- Create Alias of server and storage HBA’s.
- Alicreate.
- Create zones for server and storage by using the command.
- Zonecreate.
- We need to check whether active configurations is present or not by using the command.
- Cfgactvshow.

What is WWN in SAN?
A World Wide Name (WWN) is a unique identifier that is assigned to a manufacturer by the Institute of Electrical and Electronic Engineers (IEEE) and hard-coded into a Fibre Channel (FC) device. WWNs are important when setting up a storage area network (SAN).
What is the difference between LUN masking and zoning?
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.
What is difference LAN and SAN?
LAN, also called local area network, is a computer network that interconnects computers within a limited area such as residence, school, computer laboratory or office building. SAN, or storage area network, is a computer network which provides access to consolidated and block level data storage.
