HPE XP7 User Manual page 31

IMPORTANT:
• The components are available for selection only if they are configured on an array.
• The following metrics are NOT applicable for the XP or XP7 continuous access journal pool
LDEVs:
◦ Frontend IO metric category: LDEV Random Writes and LDEV Sequential Writes
◦ Frontend MB metric category: Random MB Write and Sequential MB Write
◦ Response Time metric category: Maximum Write Response and Average Write Response
• If you split the journal LDEVs, external RAID Group, RAID Group, ThP pool, and the snapshot
into two schedules, and in charts, you select Overall LDEVs, the combined data points from both
the schedules are plotted on the chart. In addition, repeated time stamps are displayed if the
collection frequency for both the schedules is the same. As a result, incorrect values are plotted
on the graph.
• You can select array components that belong to the same or different XP and XP7 disk arrays, or
custom groups. While selecting the components, press the Shift key for sequential selection or
the Ctrl key for random selection of multiple components.
• You can also search for physical LDEVs that belong to an array.
• Each array can be identified by its DKC or model number, you can also set personalized name
for arrays.
