Introduction
Storage Area Network (SAN)
A high-performance data communications environment that interconnects
computing and storage resources so that the resources can be effectively shared
and consolidated.
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. You can obtain this
book from the Hewlett-Packard website
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
