摘要： An apparatus is equipped with a caching function of a device driver, including a pre-fetch function that selective pre-fetches data stored in disk blocks to facilitate operation with a file system having file clusters with a cluster size greater than an underlying operating system's memory page size. The apparatus is further equipped with a disk block allocation optimization function to generate a new set of disk blocks to reallocate disk blocks for file system clusters accessed by a sequence of file accesses of interest to improve the overall access time for these file system clusters. The disk block allocation optimization function is further equipped to account for the selective pre-fetches and caching to be performed to accommodate said file system.

摘要： A system and method for generating a transportable physical level data block trace for a computer system. The method comprises capturing a first physical level data block trace on a first computer system, then performing a reverse file system lookup to generate a logical representation of that trace. That logical representation may be delivered to a second computer system, which may perform a file system lookup to convert the logical representation to a second physical level data block trace for a sequence of disk block accesses resulting from executing an application on the second computer system.

摘要： Apparatus and methods of reducing power consumption in solid-state storage devices such as solid-state disks (SSDs) that can reduce idle power levels in an SSD, while maintaining low resume latency upon exiting a reduced power state. By arranging a storage controller and at least one NAND flash package of the SSD in separate power islands, storing context information for the SSD in at least one page buffer of NAND flash memory within the NAND flash package on one power island upon entering the reduced power state, and, once the context information is stored in the page buffer, allowing the NAND flash memory to enter a standby mode, placing the storage controller on the other power island in a predefined low power mode, and removing power from any unneeded components on the same power island as the storage controller, a scalable approach to reducing idle power levels in the SSD can be achieved.

摘要： A method and apparatus for reducing the disk drive data transfer interrupt service latency penalty is described. The method comprises beginning a data transfer between a disk drive and a host system, issuing an interrupt before the transfer is complete, and then completing the data transfer. This method may be implemented on a computer assembly that includes a processor, an input/output controller, and a scatter/gather list, which is stored in memory, that includes an entry that will cause the input/output controller to generate the interrupt.
