Abstract
Implementations described and claimed herein provide systems and method for prefetching data. In one implementation, whether a read request for a first data block is part of a sequential access stream is determined. A first trigger for a subsequent data block in the sequential access stream is recorded. A first set of data blocks is prefetched. The first set of data blocks is defined by a first prefetch window associated with the first trigger. A second trigger is recorded for a second subsequent data block in the sequential access stream. A second set of data blocks is prefetched. The second set of data blocks is defined by a second prefetch window associated with the first trigger. A size of the prefetch windows may be dynamically adjusted based on resource contention with the prefetching.
