4.3.2 Device Summary Report

CAPACITY This column covers the capacity groups that are being differentiated.

<- - - - - T O T A L - - - - - > This column covers the total capacity in megabytes that has been allocated to the appropriate group in that line. The capacity is the sum of all the devices that were selected for the report.

<------ TOTALS % ------ > This column shows the percentage of capacity that the

group in the appropriate line is occupying, always compared to the 100% defined functional capacity in the first row. The percentage is based on all the devices that were selected for the report.

COMP. RATIO This column shows the real compaction ratio, which is the quotient of the total functional capacity stored/total physical used capacity and is a measure of the overall compaction for the devices selected for the report.

4.3.3 Subsystem Summary Report

SYSTEM This column identifies the system to which the capacity outlined in the appropriate line applies. If a test system has not been configured, only the PROD system information is provided.

DEFINED-CAPACITYThis column contains the functional capacity in megabytes for the whole subsystem as it has been configured.

DISK-ARRAY-CAPThis column contains the total disk array capacity in megabytes for the whole subsystem that has been installed.

FREE-DISK-ARRAY-CAPThis column contains the current free disk array capacity in megabytes that is still available for allocation by the RVA subsystem.

NET-CAPACITY-LOAD(%)This column contains the percentage of the disk array capacity that is currently being occupied by the TEST, PROD, or both (OVERALL) systems. This is probably the most important value and has been placed at the beginning of the very last report line to make it easy to find.

COLL.-FREE-SPACE(%)This column contains the percentage of the array cylinders in the subsystem that are free array cylinders (that is, the total space that can be written to).

UNCOLL-FREESPACE(%)This column contains the percentage of the array capacity originally occupied when a functional track has been rewritten to a new location in the disk array.
