Introduction

Zone (Zoning)

A zone is a group of devices or zone members in a SAN that can communicate and

access each other. Communication is only allowed between devices in the same zone.

A device can be in multiple zones so that shared resources can be accessed by many

devices. Because SANs connect many types of devices that may carry different

protocols, separating an entire fabric into zones can control access between specific

devices. Zone (or zoning) is an efficient method of managing, partitioning, and

controlling access to SAN devices. Zoning maximizes resources while maintaining

data security and enabling heterogeneous systems and products to operate in the same

SAN.

Zone Member

Specification (definition) of a device that belongs to a zone. A zone member can be

identified by the port number of the device to which it is attached or by its device or

host bus adapter or World Wide Name (WWN). In multiswitch fabrics, identification

of end-devices and nodes by WWN is preferable.

Zone Set

A zone set is composed of one or more zones. When a zone set is activated, all zones

in the set are activated at the same time. Only one zone set can be active in the fabric at

one time, and that zone set is referred to as the active zone set.

Suggested Reading

A book that can help you to prepare to install products and configure a SAN is the hp

StorageWorks SAN high availability planning guide (620-000124/AA-RS2DB-TE).

You can obtain this book from the Hewlett-Packard website (

(http://thenew.hp.com) or

from the CD shipped with the Hewlett-Packard product you purchased.

Another publication you may want to read is Compaq StorageWorks SAN Switch

Zoning Reference Guide, which is a white paper on zoning fundamentals. It is

available online from the Hewlett-Packard website (
