摘要： A storage system permits virtual storage of user data by implementing a logical disk mapping structure that provides access to user data stored on physical storage media and methods for generating point-in-time copies, or snapshots, of logical disks. A snapshot logical disk is referred to as a predecessor logical disk and the original logical disk is referred to as a successor logical disk. Creating a snapshot involves creating predecessor logical disk mapping data structures and populating the data structures with metadata that maps the predecessor logical disk to the user data stored on physical media. Logical disks include metadata that indicates whether user information is shared between logical disks. Multiple generations of snapshots may be created, and user data may be shared between these generations. Methods are disclosed for maintaining data accuracy when write I/O operations are directed to a logical disk.

摘要： Systems, methods and software for implementing a virtualized storage system. Physical storage is carved into units called physical segments. Logical storage is implemented in atomic logical units called RStores comprising a range of virtual address space that when allocated, is bound to a particular group of PSEGs. RStores preferably implement a selected level of data protection. A pool of physical storage devices is carved into redundant storage sets. A plurality of RStores make up a logical disk that is presented to a user. Storage access requests expressed in terms of logical disk addresses are mapped to PSEGs containing data represented by the logical addresses through a split-directory representation of the logical unit.

摘要： Method and apparatus for adaptive arrangement of data on storage media, such as in a multi-device storage array across which data are stored. A virtual hot space is formed to store frequently accessed data. The virtual hot space comprises at least one hot data zone which extends across storage media of a plurality of arrayed storage devices over a selected seek range less than an overall radial width of the media. The frequently accessed data are stored to the hot data zone(s) in response to a host level request, such as from a host level operating system (OS) or by a user which identifies the data as frequently accessed data. Alternatively or additionally, access statistics are accumulated and frequently accessed data are migrated to the hot data zone(s) in relation thereto. Lower accessed data sets are further preferably migrated from the hot data zone(s) to another location of the media.

摘要： Disclosed is a data storage architecture employing a plurality of data grids each comprising an array of equal capacity data storage blocks organized into a plurality of rows and a plurality of columns such that each column corresponds to a storage domain in a data storage system and each row of the plurality of rows corresponds to a plurality of data storage blocks, one data storage block from each column of the plurality of columns at the same physical address, with the plurality of rows each having a plurality of contiguous data storage blocks in each domain. Capacity grids are produce by applying one of a plurality of sparing versions that designate at least one data storage block in each row of the grid is designated as spare, Defined within each capacity grid are one or more data storage units. Each data storage unit reflects a storage format, such as a RAID level, and defines data storage blocks, mirror data blocks, and parity data blocks depending upon storage the format and can provide fault tolerance in the event of a domain failure. User data is stored exclusively in a first portion of the grid and parity data, if any, is exclusively stored in a second portion of the grid, providing optimized performance. Data access employs metadata that may comprise grid and storage unit descriptors, data storage unit format, and a sparing table.
