Zoning and Partnering with QuickLoops
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.
QuickLoop Zoning Advantages
In addition to 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, as shown in Figure 4-2.
