What is the recommended zoning method when designing fabrics for stand-alone and
clustered environments?

A.
single initiator

B.
operating system

C.
application

D.
port

Explanation:
When there is one HBA or initiator to a single storage processor port or target zone, it is
commonly referred to as single zone.

Zoning by operating system Zoning by operating system is the minimal required zoning
method. This method allows multiple HBAs with thesame operating system to be grouped
with the accessed storage ports. Zoning by operating system prevents the interaction of
HBAs with incompatible operating systems. This method limits the number of zones in
afabric. A large zone can be divided into multiple zones within the operating system type.
Zoning by operating system type limits disruptions and the number of fabric change
notifications. Certain situations require zoningby HBA, for example, configuring server
access to multiple storage types. Zoning by HBA ( or Single initiator) For zoning by HBA,
each zone has only one HBA (initiator); each of the target devices is added to the zone.
Typically, a zone is created for the HBA and the disk storage ports are added. If the HBA
also accesses tapedevices, HP recommends that a second zone be created for the HBA and
associated tape devices. For zoningrequirements with different HBA models on the same
server. This zoning philosophy is the preferred methodfor both standalone and clustered
systems; zoning by single HBA requires the creation of numerous zones; Each containing
only a few members. Zone changes affect a small number of devices, minimizing the effect
ofan incorrect zone change. Zoning by application Zoning by application configures multiple,
sometimes incompatible, operating systems into the same zones. This method allows the
potential for disruptions among servers, such as a web server disrupting a data warehouse
server. A zone with a large number of members is susceptible to more administrative errors,
such as distribution of RSCNs to a larger group than necessary. Zoning by port allocation
Avoid zoning by port allocation unless you have strictly enforced processes for port and
device allocation in the fabric. There is no consequence for the change of WWN when a
storage port, server HBA, or tape drive is replaced. If the new device connects to the original
port, it continues to have the same access rights. You can preassociate switch ports with
storage ports, and therefore control the server-to-storage ratio. This technique prevents
overloading of a storage port by allowing you to limit the number of servers that are allowed
access.
