Check boxes adjacent to the LUNs can be used for selecting and viewing the performance of up to the
first 5 Selected LUNs. View performance graphs for one of the first 5 LUNs on its tab, or view an
aggregate graph from the “All” tab.
The performance view auto-refreshes every 10 seconds and displays point-in-time MB/s and IOPS
characteristic information.
To View LUN performance graphs, do the following:
Step 1 Choose LUN Configuration > LUNs.

• To view daily performance, click the icon in the top-right-hand corner of the performance graph.
• To view weekly performance, click the calendar icon in the top-right-hand corner of the performance
graph.
• To view details of a particular time frame by click your mouse and drag it over a lower time-line
interval, e.g., 17:25 to 17:50.
Initiator Groups
Initiator Groups are used to map LUNs. When a LUN is associated with a specific Initiator Group, the
LUN is only visible to Initiators in that Group. A triangle adjacent to an Initiator Group name indicates
that there are Initiators assigned to them and a tree structure can be expanded or collapsed on click.
Note A LUN may be mapped to multiple Initiator Groups while an Initiator cannot be listed as a member of
more than one Initiator Group.
