Configuring Metric for Load Balancing

You can assign a load metric to each initiator for weighted load balancing. The load calculated is based
on the number of initiators on a given iSCSI interface. This feature accommodates initiators with
different bandwidth requirements. For example, you could assign a higher load metric to a a database
server than to a web server. Weighted load balancing also accommodates initiators with different link
speeds.
For more information on load balancing, see the
page
Choose IP > iSCSI iSLB in Device Manager and set the LoadMetric field to change the load balancing
metric for an iSLB initiator.
See the

Configuring iSLB Initiator Targets

You can configure initiator targets using the device alias or the pWWN. You can also optionally specify
one or more of the following optional parameters:
•
•
•
•
•
In addition, you can disable auto-zoning.
If you configure an IQN for an initiator target, then that name is used to identify the initiator target.
Otherwise, a unique IQN is generated for the initiator target.
To configure additional iSLB initiator targets using Device Manager, follow these steps:
Step 1 Choose IP > iSCSI iSLB.
You see the iSCSI iSLB dialog box (see
Click on the initiator you want to add targets to and click Edit Initiator Specific Targets.
Step 2
You see the Initiator Specific Target dialog box.
Click Create to create a new initiator target.
Step 3
You see the Create Initiator Specific Target dialog box shown in
