ABSTRACT:
The present invention concerns a storage method and system (1) comprising processing means (11) and storage resources (20, 100) containing firstly storage means (20) including at least one physical library (P201to P20n) and secondly memory means (100) called a cache (100), in which the processing means (11) of the storage system (1), vis-à-vis the computer platforms (101to10n), emulate at least one virtual library (V201to V20n) from at least one physical library (P201to P20n) which the storage system has under its control, characterized in that the processing means (11) of the storage system (1) comprise a management module (30) responsible for emulation and managing priorities over time for accesses to the storage resources (20, 100) using the results of calculations of at least one cache activity index per determined periods of time, and of at least one cache occupancy rate at a given time.
