Reports for logical groups displayed in the Mobility tab
You can display one of the following ranking reports for a logical group in the Mobility tab by selecting
a top folder of the Public or Private folder, and a top-level folder for each user group under the Private
Logical Group folder:
•
Bottom 10: Logical Groups with High Response Time
Checks for logical groups including volumes whose response time is slow. Used to determine lo-
gical groups which do not satisfy required performances. This ranking is displayed only when you
have the license for HP StorageWorks P9000 Performance Advisor software.
•
Top 10: Logical Groups with Lowest Unused Capacity
Checks for logical groups that have little unused capacity left for the allocated THP/Smart volumes.
Used to determine logical groups which do not have enough capacity.
•
Top 10: Logical Group Used Capacity by Drive Types
Checks for logical groups that use a large amount of capacity by drive type. Used to determine
whether an unexpected volume is occupying a high-speed drive or logical groups which have in-
valid data arrangements.
The following summary information is displayed when each logical group is selected:
•
Summary
Provides summarized information in a list, such as the number of volumes and the total capacity
of a logical group, or the last update date. Based on this information, you can review the usage
status of the storage resources in the logical group.
•
Drive Type Summary

volumes and the used capacity of each drive type within the logical group.
•
Drive Type Distribution

group. Used to check whether the configuration of the hardware tier is appropriate.
