  • Mechanism for determining read-ahead length in a storage system
    Patent number: 8732406
    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.

  • Initiation of read-ahead requests
    Patent number: 8312181
    Abstract: Example embodiments provide various techniques for initiating read-ahead requests. A rate at which applications is requesting data from a data storage device is identified. Additionally, a length of time in retrieving or servicing the data from the data storage device is also identified. The identified rate and length of time in retrieving the data are used to determine when read-ahead requests should be sent to pre-fetch data.
