What is WWN zoning?
WWN zoning (also called name zoning) restricts access by a device’s WWN. As the WWN is on the host, the port the host is connected to can be moved and access is still preserved. Connecting a new device into a port previously used by a WWN zone device will not convey any access to the previous device’s resources.
What is fabric zoning?
Fibre Channel zoning allows you to partition the Fibre Channel fabric into one or more zones. Each zone defines the set of Fibre Channel initiators and Fibre Channel targets that can communicate with each other in a VSAN. Zoning also enables you to set up access control between hosts and storage devices or user groups.
What are two major 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.
What is Zone and Zoneset?
A zone set consists of one or more zones. A zone can be a member of more than one zone set and consists of multiple zone members. Members in a zone can access each other; members in different zones cannot access each other. Devices can belong to more than one zone.
What is the need of WWN?
A WWN may be employed in a variety of roles, such as a serial number or for addressability; for example, in Fibre Channel networks, a WWN may be used as a WWNN (World Wide Node Name) to identify an endpoint, or a WWPN (World Wide Port Name) to identify an individual port on a switch.
What is zoning in SAN 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.
How do I activate Zoneset MDS?
Procedure
- Log on to the Cisco MDS switch.
- To start the configuration, type: switch-A# config terminal.
- To create or modify the zone set, type: switch-A(config)# zoneset name zoneset_name vsan vsan_id.
- To add members to the zone set, type: switch-A(config-zone)# member zone_name.
How many Zoneset can be active in a given fabric?
one zone set
– A zone set can be activated or deactivated as a single entity across all switches in the fabric. – Only one zone set can be activated at any time. – A zone can be a member of more than one zone set. – A zone switch can have a maximum of 500 zone sets.
