摘要： Provided are a computer program product, system, and method for prefetching data tracks and parity data to use for destaging updated tracks. A write request is received including at least one updated track to the group of tracks. The at least one updated track is stored in a first cache device. A prefetch request is sent to the at least one sequential access storage device to prefetch tracks in the group of tracks to a second cache device. A read request is generated to read the prefetch tracks following the sending of the prefetch request. The read prefetch tracks returned to the read request from the second cache device are stored in the first cache device. New parity data is calculated from the at least one updated track and the read prefetch tracks.

摘要： Rebuilding lost data in a distributed redundancy data storage system including multiple nodes, is provided. User data is stored as a collection of stripes, each stripe comprising a collection of data strips and associated parity strips, the stripes distributed across multiple corresponding data owner nodes and multiple corresponding parity owner nodes. A data owner node maintains the associated data strip holding a first copy of data, and a parity owner node maintains a parity strip holding a parity for the collection of data strips. Upon detecting a failure condition, the owner node initiates a rebuilding protocol for recovery of lost data and/or parity it owns. The protocol includes reconstruction of lost data or parity by a computation involving data and/or parity from a recovery strip set in a stripe, wherein a recovery strip set contains at least one surviving data or parity strip. The recovery strip set for a lost data strip contains at least one surviving parity strip.

摘要： A computer implemented method, apparatus, and computer usable program product for managing redundant array of independent drives. In response to a failure of a hard disk in a first RAID array, the process calculates an amount of free capacity available across a set of remaining hard disks in the first RAID array. The set of remaining hard disks comprises every hard disk associated with the first RAID array except the failed disk. In response to a determination that the amount of free capacity is sufficient to re-create the first RAID array at a same RAID level, the process reconstructs the first RAID array using an amount of space in the set of remaining drives utilized by the first RAID array and the free capacity to form a new RAID array without utilizing a spare hard disk.

摘要： Embodiments of the invention relate to erasure correcting codes for storage arrays. An aspect of the invention includes receiving a read stripe from a plurality of storage devices. The read stripe includes a block of pages arranged in rows and columns, with each column corresponding to one of the storage devices. The pages include data pages and parity pages, with the number of parity pages at least one more than the number of rows and not a multiple of the number of rows. The method further includes reconstructing at least one erased page in response to determining that the read stripe includes the at least one erased page and that the number of erased pages is less than or equal to the number of parity pages. The reconstructing is responsive to a multiple erasure correcting code and to the block of pages. The reconstructing results in a recovered read stripe.

摘要： Embodiments of the invention relate to storing data in a storage array. An aspect of the invention includes receiving write data. The write data is arranged into “r” rows and “n” columns of pages, with each page including a plurality of sectors. The write data is encoded using a plurality of horizontal and vertical erasure correcting codes on the pages. The encoding allows recovery from up to tr erasures in any one of the r rows, up to tr−1 erasures in any one of the remaining r−1 rows, up to tr−2 erasures in any one of the remaining r−2 rows, and so on, such that the encoding allows recovery from up to t1 erasures in the last remaining row. Encoded write data is output from the encoding. The encoded write data is written as a write stripe across n storage devices in a storage array.

摘要： According to one embodiment of the present invention, a computer manages an electric vehicle charging transaction. A set of principals is identified associated with the charging transaction for an electric vehicle. A principal is an entity having an interest in the charging transaction. Electric vehicle charging information is retrieved from a set of sources. An energy transaction plan is generated during a pre-charge phase using the electric vehicle charging information and based on preferences of one or more principals to govern the charging transaction. The computer initiates a charging phase of the electric vehicle charging transaction for an electric vehicle connected to a charging station according to the energy transaction plan. The charging phase comprises charging the electric vehicle with electricity, storing electricity in the electric vehicle, and removing electricity to de-charge the electric vehicle. The computer settles the financial obligations among principals according to the energy transaction plan.

摘要： Embodiments of the invention relate to throttling accesses to a flash memory device. The flash memory device is part of a storage system that includes the flash memory device and a second memory device. The throttling is performed by logic that is external to the flash memory device and includes calculating a throttling factor responsive to an estimated remaining lifespan of the flash memory device. It is determined whether the throttling factor exceeds a threshold. Data is written to the flash memory device in response to determining that the throttling factor does not exceed the threshold. Data is written to the second memory device in response to determining that the throttling factor exceeds the threshold.
