62 Planning: MD3600f Series Storage Array Terms and Concepts
• Using the Performance Monitor to retrieve performance data can affect
the normal storage array performance depending on the polling interval
that you set.
• If the storage array you are monitoring begins in or transitions to an
unresponsive state, an informational dialog is displayed. The dialog
informs you that the Performance Monitor cannot poll the storage array
for performance data.
To monitor the performance of the arrays:
1 Open MDSM and select the appropriate storage array.
2 Open the Array Management Window (AMW) for the selected
storage array.
3 In the AMW, select Storage Array Monitor Performance.
4 Click Settings.
a Select the components that you want to monitor. You can monitor:
• RAID controller modules
• Virtual disks
• Storage array totals
NOTE: By default, all items are selected.
b In Polling interval, select how often you want to update the
performance statistics.
NOTE: For an accurate elapsed time, do not use the Set RAID Controller
Module Clocks option while using the Performance Monitor.
Each time the polling interval elapses, the Performance Monitor queries
the storage array again and updates the statistics in the table.
5 Click Start.
Values are displayed for the selected storage arrays in the Performance
Monitor data table. The table is updated at the interval specified in the
Polling Interval setting.
6 Click Update to force an immediate poll of the storage array.
7 Click Stop to stop monitoring the storage array.
8 Click Save As on the Performance Monitor main dialog to save the
currently displayed performance statistics.
