READ PERFORMANCE ON A SATA STORAGE DEVICE BEHIND A HOST BUS ADAPTER

摘要

Examples may include a storage device coupled to a host bus adapter and a SATA controller over a SATA interface. The storage device includes a memory and a storage device controller. The storage device controller includes a collision detector and counter component to detect and count collisions on the SATA interface for a period of time; and a bus limiter component to detect a type of workload on the SATA interface, and when the detected workload is only read commands and a number of detected collisions is less than a detected collision threshold during the period of time, to set a limit on a maximum number of commands sent by the host bus adapter to the storage device controller over the SATA interface.
