STORAGE WORKLOAD HINTING

摘要

Methods and structure for reconfiguring storage systems are provided. One exemplary embodiment is a storage controller. The storage controller includes a memory that stores multiple profiles that are each designated for a different type of Input/Output processing workload from a host, and each include settings for managing communications with coupled storage devices. Each type of workload is characterized by a pattern of Input/Output requests from the host. The storage controller also includes a control unit able to process host Input/Output requests at the storage controller in accordance with a first profile, identify a change in type of workload from the host, and load a second profile designated for the changed type of workload in place of the first profile. The control unit is also able to process host Input/Output requests at the storage controller in accordance with the second profile.
