  • Data storage systems using time-based read ahead
    Patent number: 10990289
    Abstract: A data storage system includes a host system configured to provide an I/O request stream and a data storage subsystem. The data storage subsystem has a data storage device and a processor. The processor is configured to provide streaming data in response to the I/O request stream, determine a current streaming rate of the I/O request stream, and determine a time-based read ahead size based on a time ahead duration and the current streaming rate of the I/O request stream. The time-based read ahead size may be updated while streaming, for example, after a delay period.
    Type: Grant

  • Read ahead management in a multi-stream workload
    Patent number: 10621096
    Abstract: Implementations described and claimed herein provide a method and system for managing execution of commands for a storage device, the method comprising identifying individual streams processing read ahead operations in a storage controller, determining an amount of read ahead data that each individual stream is processing in the read ahead operations, determining a total amount of read cache available for the storage controller, and determining a total amount of read ahead data that all the individual streams are processing in the read ahead operations.
