摘要： In a computer system, a bus adapter processes bus operation information structures for performing bus operations by automatically starting processing each bus operation information structure after completing processing the previous bus operation information structure. A processor forms the bus operation information structures and sets control over each bus operation information structure to a sequencer for processing. When a next bus operation information structure is ready for processing after completing processing the previous bus operation information structure, the sequencer checks whether it has control over the next bus operation information structure, and if so, begins processing the next bus operation information structure without being instructed to do so by the processor.

摘要： Circuits and associated methods for testing internal operation of an application integrated circuit. Features and aspects hereof add configurable test interrupt circuits to an application circuit design to permit dynamic, configurable interrupt generation from an integrated circuit based on conditions determined from monitoring of internal signals of the application circuit. The internal signals that may be tested and used to generate test interrupts are those not exposed to the external processor interface of the integrated circuit and thus may be configured to interrupt based on any internal state of the application specific functional circuits of the integrated circuit.

摘要： Methods and systems for improved management of power allocation among a plurality of devices coupled to a controller. The controller and devices exchange messages to request, grant, and release allocations of power from a common power supply. In some embodiments, the controller may be a SAS/SATA controller and the messages exchanged may be SAS/SATA frames and/or primitives. In exemplary embodiments, the messages may request/grant a particular amount of power for each of one or more voltage levels provided by the power supply. In other exemplary embodiments, the messages may designate the duration of time during which the requesting device may utilize the allocated power. A power status message from the device to the controller may indicate a change in the power consumption by the device. Responsive to the power status message the controller may re-allocate power previously allocated to a device that has completed use thereof.

摘要： The present invention is directed to a method and system for efficient write journal entry management maintaining minimum write journal information stored in a nonvolatile memory through utilizing an additional structure in a fast volatile memory. The method and system may manage write journaling of a file volume including multiple fixed sized regions and assign a persistent 1-bit synchronization status (the write journal information) to each data region. In addition, a non-persistent I/O counter (the additional structure) for each region to manage the persistent 1-bit synchronization status during run-time. The present invention may provide a mechanism to determine when write I/O operations have not successfully completed to a specific region of the file volume.

摘要： Systems and methods for improving performance of a re-synchronization process in a RAID level 1 storage system. In one aspect a local cache memory associated with the second or mirrored disk drive is enabled during the re-synchronization operation but left disabled during normal operation processing host requests. The cache is flushed to the persistent medium of the second disk drive before resuming normal I/O request processing. In another aspect normal I/O request processing is interleaved with portions of the processing for re-synchronization of the mirrored disk drive. Normal I/O request processing proceeds for a first period of time. Re-synchronization processing for a portion of the mirrored information then proceeds (with local cache memory of the mirrored disk drive enabled) for a second period of time.

摘要： Methods and structure are disclosed for normalizing storage performance across a plurality of logical volumes. One embodiment is a storage controller. The storage controller is adapted to couple with a plurality of host systems and a storage device. The storage controller is adapted to receive one or more requests to create logical volumes for the plurality of hose systems, and adapted to identify a plurality of performance zones for storage areas of the storage device. The performance zones exhibit different performance criteria for one or more of: reading data from the storage device and writing data to the storage device. The storage controller is further adapted to allocate storage from each of the plurality of performance zones for each of the plurality of logical volumes such that the performance criteria for accessing the storage device is distributed substantially uniformly across the plurality of logical volumes.
