Abstract:
A system having input/output hot spot tracking is disclosed. The storage system includes a storage device, a host controller coupled to the storage device, and a tracking engine coupled to the host controller and the storage device. The host controller is configured to managed input/output of the storage device. The tracking engine includes a storage map cycling between active status and passive status. Input/output commands are stored in the storage map during the active status. Like input/output commands in the storage map during active status are counted and compared to a number. Counts greater than the number are reported as input/output hot spots.
