Quickloop Fabric Assist User Guide
Configuration 4: Mixed QuickLoop Mode and Fabric Mode
Figure 4 shows a sample configuration of a mixed mode environment, with ports
set on an individual basis to either QuickLoop mode or Fabric mode. In this
example, a fabric is formed from two cascaded switches, Compaq 1 and
Compaq 2.
■
The ports to which the looplets within the QuickLoop are attached, ports
(1,14), (1,15), (2,0), and (2,1), are all QuickLoop-enabled FL_Ports.
■
Private target device
a
and public target device
f
are attached to FL_Ports
(1,0) and (2,14).
■
Public host
G
is attached to an F_Port, (1,1).
■
Because it is in the same QuickLoop, private host
J
can access the private
target devices
b
and
c
even though they are attached to a different switch.
