Considerations for zoning architecture Table 88 lists considerations for zoning architecture. Table 88 Considerations for zoning architecture Item Type of zoning: hard or soft (session-based) Use of aliases Interoperability Fabric QLFA zones Testing Description If security is a priority, hard zoning is recommended. The use of aliases is optional with zoning. Using aliases requires structure when defining zones. Aliases will aid administrators of zoned fabric in understanding the structure and context. If the fabric includes a third-party switch product, only WWN zoning is supported. Other types of zoning, including QuickLoop, are not supported. Evaluate if the fabric will have QuickLoop Fabric Assist (QLFA) or QuickLoop (QL) in it, and consider the following items before creating and setting up QLFA zones: QuickLoop Zoning-QuickLoop/QuickLoop zones cannot run on Fabric OS 4.1.0 or later. However, Fabric OS can manage (create, remove, update) QL zones. QuickLoop Fabric Assist-A switch running Fabric OS 4.1.0 or later cannot have a Fabric Assist host directly connected to it. However, such a switch can be part of a Fabric Assist zone if a Fabric Assist host is connected to a compatible switch in the fabric. Before implementing a new zone, you should run the Zone Analyzer from Web Tools to isolate any possible problems. This is especially useful as fabrics increase in size. 390 Administering Advanced Zoning
