HP XP P9000 Performance Advisor Software v6.0 Install Guide

NOTE:
• Selecting a ThP, snapshot, or a continuous access journal volume also provides the
respective volume pool information.
• The THP Group(s), CA Journal Group(s), and the SNAP Group(s) component type lists are
displayed only if the corresponding components are configured on the selected XP or the
P9000 disk array. The External RG(s) component type list is displayed only if the external
volumes are attached to the selected XP or the P9000 disk array.
• If you want all the corresponding components to be selected, choose the Select All check
box in a particular component type list box. The Select All check box is provided for each
component type list.

8. Set the frequency in minutes for the DKC, RAID groups, and the port performance data collection
by selecting the frequency from the respective Frequency list.
9. Select the check box for Stagger Schedule if you want to stagger the data collection time at
different intervals.
For example, Stagger Schedule check box is not selected, and Frequency is set to 15 minutes,
performance data collection occurs at every quarter, irrespective of when the schedule is
created. Example, if the schedule is created at 10.12 a.m., the first collection occurs
immediately and the next collection occurs at the quarter of the hour, which is 10.15 a.m.
The subsequent collection occur at 10.30 a.m., 10.45 a.m., and so on. If you check Stagger
Schedule, performance data collection occurs every 15 minutes from the time the schedule is
created. For example, if the schedule is created at 10.12 a.m., the first collection occurs
immediately, and the next collection is 15 minutes later, at 10.27 a.m. The subsequent
collection take place every 15 minutes after that.
The Stagger Schedule ensures that the load on the management server is balanced, because
the data collection occurs for all the XP and the P9000 disk arrays at varied points of time in
the day and not every 15 minutes of the hour.
