Using QuickLoop Zones

QuickLoop Zoning Advantages
In addition to the advantages of fabric zoning—security, customized
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.
