Key Terms Fabric Storage Area Network (SAN) Zone (Zoning) Zone Member Zone Set Key Terms 1 Here are key terms that will help you perform tasks such as zoning. Entity that interconnects N_Ports and is capable of routing (switching) Fibre Channel frames using the destination ID information in the Fibre Channel frame header accompanying the frames. A high-performance data communications environment that interconnects computing and storage resources so that the resources can be effectively shared and consolidated. 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. A 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. 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, by its device, by host bus adapter, or by world-wide name (WWN). In multiswitch fabrics, identification of end-devices and nodes by world wide name is preferable. A set 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.
