Packs detailed cache-layer statistics for four open volumes per table row: read/write command and hit counts, prefetch hits, staging and writeback counts, and sequential-access counts. Admins use these hit-rate figures to judge whether a given volume's working set fits well in cache or is generating excessive staging I/O.
