摘要： A disk array has a plurality of 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 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 hierarchic disk array data storage system has multiple storage disks that define a physical storage space and a RAID management system that maps the physical storage space into two virtual storage spaces. A RAID-level virtual storage space presents the physical storage space as mirror and parity RAID areas where the mirror RAID areas store data according to RAID Level 1 and the parity RAID areas store data according to RAID Level 5. An application-level virtual storage space presents the physical storage space as multiple virtual blocks. The RAID management system migrates data between the mirror and parity RAID areas to optimize performance and reliability. To facilitate migration, the RAID management system guarantees a minimum of unused storage space that can be used to empty a RAID area for the purpose of converting the RAID level or other storage attribute of the RAID area. The minimum unused storage space is preferably equivalent in size to at least one largest parity RAID area. However, the unused storage space is not in any one physical location, but can be allowed to distribute itself over various RAID areas in a non-contiguous manner across the storage disks.

摘要： A disk array data storage system has a plurality of storage disks and a disk array controller for coordinating transfer of user data to and from the storage disks. A memory manager is provided to manage memory allocation and data storage on the disk array. The memory manager maintains a sufficient quantity of hot spare storage space that can be made available for reconstructing the user data and restoring redundancy in the event one of the storage disks fails. Until a disk fails, however, the memory manager uses the hot spare space to store user and redundant data while guaranteeing that the storage space can be used for rebuilding following a storage disk failure. In this manner, all storage disks in the array are used to store user data, and additionally to maintain storage space that can be easily made available for purposes of hot spare in the event of disk failure.

摘要： A method is described for enlarging the storage capacity of a hierarchical disk array data storage system which stores data according to different levels of redundancy, or RAID levels. The method includes first mapping the physical storage space into a first virtual storage space having a plurality of RAID areas that extend across multiple storage disks in the disk array and comprise multiple stripes of segments from each storage disk. The first virtual storage space is mapped into a second virtual storage space having multiple virtual blocks. To enlarge storage capacity, one or more storage disks are added to the hierarchic disk array. To assimilate the new storage capacity, data in a selected existing RAID area is moved to another area on the disk array of equal or greater storage capacity. The mapping of the second virtual storage space to the first is updated to reflect the data movement. The physical storage space corresponding to the selected RAID area is then remapped into an expanded RAID area which spans across all storage disks, including the new disks. The process is repeated until all RAID areas in the hierarchic disk array have been expanded to include regions on the new storage disks. The capacity available to the second virtual storage space is modified to reflect the enlarged storage capacity. According to this method, data remains available to the user at all times during the enlargement process.

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.

摘要： A disk array data storage system has plural sets of storage disks connected to multiple corresponding I/O buses. Individual storage disks can be independently and asynchronously attached to or detached from corresponding interfacing slots of the I/O buses. The system has physical device drivers which represent the storage disks with respect to their connections to the interfacing slots of the I/O buses and physical device managers which represent the data kept on the storage disks. Interface drivers are provided to manage I/O transfers through corresponding I/O buses. When a particular storage disk is attached to or detached from an interfacing slot of an I/O bus, the interface driver corresponding to the I/O bus freezes all I/O requests that come from the physical device drivers that represent the storage disks in the set connected to the I/O bus. A configuration manager determines which interfacing slot the particular storage disk has been attached to or detached from. If the particular storage disk has been detached from the I/O bus, the configuration manager eliminates the physical device driver that represents the detached storage disk. The data stored on the detached storage disk is rebuilt using redundancy on the remaining disks. If the particular storage disk has been attached to the I/O bus, the configuration manager creates a new physical device driver to represent the attached storage disk. The I/O requests to the I/O bus are then unfrozen.

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.
