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.
When devices are included in a zone, they are visible only to other devices
within that zone.
QuickLoop zone members are designated by looplet (port number), or by
Arbitrated Loop Physical Address (AL_PA). There are 126 unique AL_PAs
per QuickLoop; therefore, a QuickLoop zone can contain no more than
126 devices.
Configuring QuickLoop Zones
Configure QuickLoop Zoning:
1. Create a QuickLoop.
A QuickLoop is comprised of FL_Ports on one or two switches within
the fabric. To create a QuickLoop, specify a QuickLoop name (referred
to as a qloop name for zoning), followed by a list of AL_PAs to be
included. QuickLoop names define the switch (or pair of switches) that
make up the QuickLoop.
