Enterprise Fabric Mode -
Use the Enterprise Fabric Mode option
from the Configure menu (SAN management application) to
enable or disable EFM. Fabric binding is activated when EFM is
enabled.
•
Fabric binding -
Use the Fabric Binding from the Configure option
from the Configure menu (SAN management application) to lock
parameters of a fabric in accordance with the user configuration.
Fabric binding creates a membership list of element (director or
switch) Domain_IDs and WWNs that can communicate with the
product.
•
Switch binding -
Use the Switch Binding option from the
Configure menu (Element Manager application) to create a
membership list of node (device) WWNs that can attach to the
product. The specified connection policy restricts product access
through E_Ports, F_Ports, or in general (all ports).
To configure optional features, refer to the EFC Manager Software
Release 9.0 User Manual (620-000170) for instructions.
Configure interswitch links
This section describes optional ISL performance features configured
through the SAN management or Element Manager applications. The
OpenTrunking PFE key must be installed (
Install PFE keys (optional)
on page 47). Features include:
•
OpenTrunking -
Use the OpenTrunking option from the Configure
menu (Element Manager application) to optimize ISL bandwidth.
The feature monitors data rates (congestion and BB_Credit
starvation) through multiple ISLs and load balances traffic (from
congested to uncongested links) accordingly.
•
Preferred path -
Use the Preferred Path option from the Configure
menu (Element Manager application) to specify and configure
one or more ISL data paths between multiple fabric elements. At
each fabric element, a preferred path consists of a source port, exit
port, and destination Domain_ID.
•
Port fencing -
Use the Port Fencing option from the Configure
menu (SAN management application) to minimize ISLs that
bounce (repeatedly attempt to establish a connection), causing
disruptive fabric rebuilds. Fencing defines a bounce threshold
that when reached, automatically blocks the disruptive E_Port.
