Abstract: A storage controller of a data storage subsystem including a plurality of storage devices in a redundant array of independent drives (RAID) configuration writes a first RAID stripe to the plurality of storage devices. Writing the first RAID stripe includes for each storage device of a subset of the plurality of storage devices, writing within a page of the storage device, user data, and checksums that validate the user data stored on storage devices of the subset of the plurality of storage devices and writing, within a page of a particular storage device of the plurality of storage devices inter-device redundancy data, intra-page error recovery data, and inter-page protection data.

Abstract: A system and method for offset protection data in a RAID array. 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 is configured to store user data in a first page of a first storage device of the plurality of storage devices; generate intra-device protection data corresponding to the user data, and store the intra-device protection data at a first offset within the first page. The controller is further configured to generate inter-device protection data corresponding to the first page, and store the inter-device protection data at a second offset within a second page in a second storage device of the plurality of storage devices, wherein the first offset is different from the second offset.

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.

Abstract: A system and method for dynamic RAID geometries. 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 is configured to configure a first subset of the storage devices for use in a first RAID layout, the first RAID layout including a first set of redundant data. The controller further configures a second subset of the storage devices for use in a second RAID layout, the second RAID layout including a second set of redundant data. Additionally, the controller configure an additional device not included in either the first subset or the second subset to store redundant data for both the first RAID layout and the second RAID layout. The controller is further configured to initiate a reconstruct read corresponding to a given read request directed to a particular storage device of the plurality of storage devices, in response to determining the particular storage device is exhibiting a non-error related relatively slow read response.
