摘要： Protection from uncorrectable media errors are provided for a RAID-configured storage system by a technique in which c redundancy information sectors are associated with n data information sectors. The n data sectors and c redundancy information sectors are then written as a single segment on a single storage unit. The RAID-configured storage system can be configured, for example, as a RAID 6 storage system, a RAID 5 storage system, a RAID 51 storage system, a RAID 3+3 storage system or a RAID N+3 storage system. The redundancy information can be based on a Reed-Solomon code, an XOR-based code, or one-dimensional parity.

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： A bladed storage servicing system comprising a RAID layout facilitates the removal of one or more functional storage devices in a tray of the bladed storage subsystem in order to service a failed storage device. Upon removal of the tray from the bladed storage subsystem, the system designates the functional storage devices on the tray as temporarily removed. The system logs writes to the removed functional storage devices so that the functional storage devices can be returned to consistency when replaced in the bladed storage subsystem. The system manages reads to the removed functional storage devices through reconstruction from active storage devices in the bladed storage subsystem. Upon reinsertion of the tray in the bladed storage subsystem, the system verifies the identities of the functional storage devices and resynchronizes the functional storage devices to ensure data consistency.
