International Classification:

G06F 3/00
G06F 12/00
G06F 13/00
G06F 13/28

US Classification:

710 19, 710 15, 710 18, 711118, 711119

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.

US Classification:

711141, 711E12017, 711156, 711E12001

Abstract:

A storage system is disclosed including storage devices configured to store data, and a logical storage volume coupled to the storage devices and configured to store a subset of the data as segments. The storage system also includes a controller including a cache and memory. The memory is configured to include records such that each record corresponds with a segment in the logical storage volume and each record includes information regarding data stored in the corresponding segment. The controller is configured to access the records in response to a cache miss of the cache to determine if requested data from the cache miss is stored and ready for access in the logical storage volume. The controller is also configured to update the subset of data stored in the segments as a function of cache misses.

International Classification:

G06F 9/455

Abstract:

To emulate a hardware component of a target hardware system including a plurality of hardware components, a component model of the hardware component is built, where the component model includes a register interface through which a host application provides inputs to and reads outputs from the component model, one or more parameter registers that hold values of state variables of the component model, and a state machine that models behavior of the hardware component without explicitly emulating logic implemented in the hardware component. During modeling of the hardware component utilizing the component model the component model is dynamically modified other than by modifying values of the state variables.
