Abstract
A storage system tracks statistical behavior of client read requests directed to a storage device to form prediction about data that the client will require next. The storage system collects the size of read sequences for various streams into a data structure, which summarizes past behavior of read requests. This data structure reports the number of streams in each equivalence class of stream sizes that is tracked. The data structure is then used to determine expected size of a selected read stream. The data structure is also used to improve predictions about an expected size computed by a known technique.
