    Abstract: A system and method for scheduling read and write operations among a plurality of solid-state storage devices. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array comprises an I/O scheduler. The data storage controller is configured to receive requests targeted to the data storage medium, said requests including a first type of operation and a second type of operation. The controller is further configured to schedule requests of the first type for immediate processing by said plurality of storage devices, and queue requests of the second type for later processing by the plurality of storage devices. Operations of the first type may correspond to operations with an expected relatively low latency, and operations of the second type may correspond to operations with an expected relatively high latency.

    Abstract: Preparing data for deduplication including in response to receiving a request to transfer data from a source storage system to a target storage system, accessing, by the source storage system, a compressed data block; generating, by the source storage system, a padded compressed data block by padding the compressed data block to conform to a fixed block size, wherein the fixed block size is greater than a size of the compressed data block; and sending, by the source storage system, the padded compressed data block to the target storage system.

    Abstract: An apparatus, method, and computer-readable storage medium for allowing a block-addressable storage device to provide a sparse address space to a host computer. The storage device exports an address space to a host computing device which is larger than the storage capacity of the storage device. The storage device translates received file system object addresses in the larger address space to physical locations in the smaller address space of the storage device. This allows the host computing device more flexibility in selecting addresses for file system objects which are stored on the storage device.

    Abstract: A storage controller coupled to a storage array comprising one or more storage devices initiates a transformation of data from a block-based storage system resident on the storage array to a file-based storage system resident on a storage array. The storage controller identifies a plurality of data blocks to be transformed from the block-based storage system and generates metadata for a file in the file-based storage system, the metadata to associate the plurality of data blocks with the file.

    Abstract: A system and method for effectively scheduling read and write operations among a plurality of solid-state storage devices. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array comprises an I/O scheduler. The characteristics of corresponding storage devices are used to schedule I/O requests to the storage devices in order to maintain relatively consistent response times at predicted times. In order to reduce a likelihood of unscheduled behaviors of the storage devices, the storage controller is configured to schedule proactive operations on the storage devices that will reduce a number of occurrences of unscheduled behaviors.
