Using QuickLoop Zones

In addition to zoning fabrics, covered in
QuickLoops. By partitioning selected devices within a QuickLoop into a
QuickLoop zone, you can enhance management of a Fibre Channel Arbitrated
Loop (FC-AL) in a legacy environment.
In QuickLoop zoning, devices within a QuickLoop can be partitioned off within
that QuickLoop to form QuickLoop zones. In other words, a QuickLoop zone is a
subset of a QuickLoop and can include only QuickLoop devices.
Fabric zones and QuickLoop zones are independent of each other; both types of
zone can coexist in the same zone configuration; QuickLoop devices can be
included within a fabric zone configuration.

QuickLoop Zoning Advantages

In addition to all the advantages of fabric zoning—security, customization of
environments, and optimization of IT resources—QuickLoop zoning can protect
devices from disruption by unrelated devices during a critical process; for
example, during a tape backup session.
In a QuickLoop with zoning enabled, transmission of the loop initialization
primitive (LIP) signal and loop initialization are controlled by the switch; the LIP
is transmitted only to looplets within the affected zone; other looplets on the
QuickLoop are not affected. In this way, unwanted disruption to devices can be
controlled.

QuickLoop Zones

QuickLoop zones are hardware enforced; switch hardware prevents unauthorized
data transfer between ports within the zone allowing devices to be partitioned into
zones to restrict system access to selected devices. Once devices are included in a
zone, they are visible only to other devices within that zone.
