摘要： Various embodiments of the present invention provide fault-tolerant, redundancy-based data-storage systems that rely on disk-controller-implemented error detection and error correction, at the disk-block level, and RAID-controller-implemented data-redundancy methods, at the disk and disk-stripe level, in order to provide comprehensive, efficient, and system-wide error detection and error correction. Embodiments of the present invention use disk-level and stripe-level data redundancy to provide error detection and error correction for stored data objects, obviating the need for certain costly, intermediate levels of error detection and error correction commonly employed in currently available fault-tolerant, redundancy-based data-storage systems.

摘要： Embodiments of the present invention are directed to methods, and distributed data-storage systems employing the methods, for recovering redundancy within a distributed data-storage system upon failure of one or more mass-storage devices within a component data-storage system of the distributed data-storage system. In certain embodiments, failure of a mass-storage device within a component data-storage system elicits a redundancy-recovery operation in which segments affected by the mass-storage-device failure or failures are moved, by a process referred to as “migration,” to other component data-storage systems of the distributed data-storage system, and are recovered as a by-product of migration. Certain embodiments of the present invention more efficiently address redundancy recovery by moving only as many segments from the component data-storage system as needed to provide sufficient free space within the component data-storage system to recover the remaining segments affected by the mass-storage-device failure or failures within the component data-storage system.

摘要： The methods concern fully utilizing storage capacity in a heterogenous hierarchic disk array having storage disks of differing capacities. The disks are segmented into multiple regions. One method links non-contiguous regions from individual storage disks to form RAID areas. The RAID areas are mapped into a virtual storage space that provides a view of the physical storage space as a single storage volume. Data is then stored in these RAID areas according to different redundancy criteria, such as RAID Level 1 and RAID Level 5. A second method fully utilizes of storage capacity by configuring the heterogeneous disk array to employ a minimum of two equal-sized storage disks that have larger capacity than other individual storage disks in the disk array. The contiguous regions across the multiple disks are then grouped together to form the RAID areas.

摘要： A data memory system has a hierarchic disk array of multiple disks, a disk array controller for coordinating data transfer to and from the disks, and a RAID management system for mapping two different RAID areas onto the disks. The RAID management system stores data in one of the RAID areas according to mirror redundancy, and stores data in the other RAID area according to parity redundancy. The RAID management system then shifts or migrates data between the mirror and parity RAID areas on the disks in accordance with a predefined performance protocol, such as data access recency or access frequency. The data memory system also includes a memory map store embodied as a non-volatile RAM. The memory map store provides persistent storage of the virtual mapping information used by the RAID management system to map the first and second RAID areas onto the disks within the disk array. The RAID management system updates the memory map store with new mapping information each time data is migrated between mirror and parity RAID areas.

摘要： A computer storage management system responds to a recognition of an insufficiency of disk storage space available by converting inefficiently used storage space to efficiently used space and free space. The management system controls allocation of storage space to storage space consumers pursuant to an allocation ordering scheme which ensures fairness of storage space consumption among competing consumers. Generation of free storage space and allocation of space are substantially concurrent events, creating a continuous flow of space generation and space consumption. Storage space is consistently kept and used in an efficient manner, and competing processes are allocated storage space fairly and effectively.
