Abstract
A cache management system and method allowing data stored in non-sequential storage blocks on a storage system to be retrieved to a cache memory in advance of a call for the data based on a defined event in a host. The system and method detects a defined event from the host. The defined event issues an event read sequence of read requests for data from non-sequential storage blocks of a storage system. The event data read sequence of read requests is recorded to create a pre-fetch list. The read requests in the event read sequence are then issued for the pre-fetch list associated with the defined event to store the requested data in the cache memory.
