Figure 56. IXFP Space Utilization Subsystem Report
The fields to review are as follows:
• NET CAPACITY LOAD (%) PROD is the percentage of back-end physical
capacity that is used (not free) in the subsystem. This includes user data and
the system areas needed to maintain the arrays. NCL does not include data in
the cache until the data is written to the back-end disk storage.
• COMP RATIO is the approximate ratio of functional capacity stored to the
physical capacity used (on a subsystem level).
