Enterprise Fabric Mode
Enterprise Fabric Mode is an option available on the Fabrics menu in the
HAFM application if the SANtegrity Binding feature key is installed. This option
automatically enables the following features and operating parameters that are
necessary in multiswitch Enterprise Fabric environments. Note that there are
specific requirements for disabling these parameters and features when the
director or switch is offline or online.
Features and Parameters Enabled
Fabric Binding
This is a SANtegrity Binding feature enabled through the Fabrics menu in HAFM
that allows or prohibits switches and directors from merging with a selected
fabric. See “
Enable/Disable and Online State Functions ” on page 203 for details
on enabling/disabling Fabric Binding with Enterprise Fabric Mode enabled.
Switch Binding
This is a SANtegrity Binding feature enabled through the Configure menu in the
Element Manager that allows or prohibits switches and/or directors from
connecting to switch E_Ports, devices from connecting to F_Ports. See
“
Enable/Disable and Online State Functions ” on page 203 for details on
enabling/disabling Switch Binding with Enterprise Fabric Mode enabled.
Rerouting Delay
Rerouting delay is a parameter in the Configure Switch Parameters dialog box,
available from the Configure menu in the Element Manager.
Rerouting Delay ensures that frames are delivered through the fabric in order to
their destination. If there is a change to the fabric topology that creates a new path
(for example, a new switch is added to the fabric), frames may be routed over this
new path if its hop count is less than a previous path with a minimum hop count.
This may result in frames being delivered to a destination out of order since
frames sent over the new, shorter path may arrive ahead of older frames still in
route over the older path. If Rerouting Delay is enabled, traffic ceases in the fabric
for the time specified in the E_D_TOV field of the Configure Fabric Parameters
dialog box (Configure menu). This delay enables frames sent on the old path to
exit to their destination before new frames begin traversing the new path.
If Enterprise Fabric Mode is enabled, this parameter is automatically enabled and
cannot be disabled unless the director or switch is offline. In this case, disabling
Rerouting Delay also disables Enterprise Fabric Mode.
