Rules of Zoning Architecture
Here is a list of the rules of zoning architecture.
H
Rule 1 Type of Zoning (Hard or Soft)—If security is a priority, then a Hard
zoning is recommended.
Rule 2 The use of aliases is optional with zoning. Using aliases should
force some structure when defining zones. Aliases will also aid
future administrators of the zoned fabric in understanding the
structure and context.
Rule 3
Evaluate the security requirements of the fabric. Add HP Secure
Fabric OS into the fabric if extra security is required.
Rule 4 Inter-operability Fabric—If the fabric includes a StorageWorks
Core switch or StorageWorks 2 Gb SAN switch and the user needs
to support a third-party switch product, then that user will only be
able to do WWN zoning. Other types of zoning, including
QuickLoop zoning, will not be supported.
Rule 5
Evaluate whether the fabric will have QuickLoop Fabric Assist
(QLFA) or QuickLoop (QL) in it. If the user is running HP Fabric
OS V4.1, then there are a couple things to consider before creating
and setting up QLFA zones:
QuickLoop Zoning—QuickLoop/QuickLoop zones cannot run
on switches running HP Fabric OS V4.1. HP Fabric OS V4.1
can still manage (create, remove, update) QL zones on any
non-V4.1 switch.
QuickLoop Fabric Assist—HP Fabric OS V4.1 cannot have a
Fabric Assist host directly connected to it. However, HP Fabric
OS V4.1 can still be part of a Fabric Assist zone if a Fabric
Assist host is connected to a non-V4.1 switch.
Rule 6 Testing a (new) zone configuration
—
Before implementing a zone, the
user should run the Zone Analyzer from Web Tools to isolate any
possible problems. This is especially useful as fabrics increase in size.
