Zusammenfassung:A system for data management in a computing storage environment includes a processor device, operable in the computing storage environment, that divides a plurality of counters tracking write and discard storage operations through Non Volatile Storage (NVS) space into first, accurate, and second, fuzzy, groups where the first, accurate, group is one of updated on a per operation basis, while the second, fuzzy, group is one of updated on a more infrequent basis as compared to the first, accurate group.
