What is SAN switch zoning?

SAN zoning is a method of creating logical groups over the physical configuration of the fabric and allowing communication / access of Fibre Channel devices by grouping them . And zoning manages communication of hosts and storage nodes , zone contains WWN name of these devices .

What is WWN in SAN switch?

SAN-connected devices are identified by a unique identifier, known as the WWN (or world wide name). Switch WWN identifiers are a 64-bit number that has eight colon-separated fields each consisting of one or two hexadecimal digits between 0 and ff.

What is WWN zoning?

Zoning based on World Wide Name (WWN) specifies the WWN of the members to be included within the zone. When zoning in ONTAP, you must use World Wide Port Name (WWPN) zoning. WWPN zoning provides flexibility because access is not determined by where the device is physically connected to the fabric.

What is a benefit of WWN zoning over port zoning?

What is a benefit of WWN zoning over port zoning? A server, after being moved to another switch port in the fabric, maintains connectivity to its zone partners without the need to modify the zoning configuration.

How is zoning applied to a switch port?

Port and WWN zoning. Zoning can be applied to either the switch port a device is connected to OR the WWN World Wide Name on the host being connected. As port based zoning restricts traffic flow based on the specific switch port a device is connected to, if the device is moved, it will lose access.

What does WWN zoning mean for storage area network?

WWN zoning groups a number of WWNs in a storage-area network 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.

Do you use the WWN or WWPN when zoning an FC switch?

On my Brocade fiber switch I guess I use the WWN and create an Alias. Are you creating the Alias to associate? Not sure if the helps in any way. I thought the WWN was the for the HBA, and the WWPN was the PORT on the HBA. That way you could if you wanted to zone by ports but the WWN encompasses both. So… your mileage may vary.

What do you need to know about zoning with San?

This article will discuss the following zoning scenarios: PWWN (Port World Wide Name) zoning and device-alias zoning with SAN (Storage Area Networking). What devices will you be zoning together?
