摘要： Two data storage systems are interconnected by a data link for remote mirroring of data. Each volume of data is configured as local, primary in a remotely mirrored volume pair, or secondary in a remotely mirrored volume pair. Normally, a host computer directly accesses either a local or a primary volume, and data written to a primary volume is automatically sent over the link to a corresponding secondary volume. Each remotely mirrored volume pair can operate in a selected synchronization mode including synchronous, semi-synchronous, adaptive copy—remote write pending, and adaptive copy—disk. Direct write access to a secondary volume is denied if a “sync required” attribute is set for the volume and the volume is not synchronized.

摘要： A data storage system which automatically provides and maintains identical secondary data on a preferably geographically remote secondary data storage device. The system includes a primary host computer located in the first geographic location which is coupled to a primary data storage system also located in the first geographic location. The primary data storage system includes at least one primary data storage device on which primary data is to be stored, and a primary data storage system controller which receives data from the primary host computer and controls the storing of the primary data on the primary data storage device. The primary data storage controller is coupled by high speed communication link to a secondary data storage system controller of a secondary data storage system, and coordinates the copying of the primary data to the secondary data storing system, and is responsive to an acknowledgement from the secondary data storage system controller of at least successful receipt of the primary data for updating the maintained list of the primary data to indicate that the copied primary data has been received by the secondary data storage system to be copied to the secondary data storage device.

摘要： Two data storage systems are interconnected by a data link for remote mirroring of data. Each volume of data is configured as local, primary in a remotely mirrored volume pair, or secondary in a remotely mirrored volume pair. Normally, a host computer directly accesses either a local or a primary volume, and data written to a primary volume is automatically sent over the link to a corresponding secondary volume. Each remotely mirrored volume pair can operate in a selected synchronization mode including synchronous, semi-synchronous, adaptive copy-remote write pending, and adaptive copy-disk. Direct write access to a secondary volume is denied if a “sync required” attribute is set for the volume and the volume is not synchronized. If a “volume domino” mode is enabled for a remotely mirrored volume pair, access to a volume of the pair is denied when the other volume is inaccessible. In a “links domino” mode, access to all remotely mirrored volumes is denied when remote mirroring-is disrupted by an all-links failure. The domino modes can be used to initiate application-based recovery, for example, recovering a secondary data file using a secondary log file. In an active migration mode, host processing of a primary volume is concurrent with migration to a secondary volume. In an overwrite cache mode, remote write-pending data in cache can be overwritten. Write data for an entire host channel command word chain is bundled in one link transmission.

摘要： A data storage system includes data storage and a record locator data structure in random access memory. The record locator data structure includes entries having different lengths. For locating variable-length data records in the data storage, for example, at least some but not all of the entries have a data-length portion indicating data length of a respective data record of the entry when the data length of the respective data record fails to match an expected data length. Each entry, for example, has a fixed length portion including an indication of whether or not the entry has a data-length portion, the fixed length portions are stored sequentially in a first region of address locations of the random access memory, and the data-length portions are stored sequentially in a second region of address locations of the random access memory.

摘要： A disk storage system including means for assuring completion of data writes to a data storage disk upon failure of electrical power receives data write commands including data to be written to one or more storage disks. Temporary memory storage temporarily stores the write commands including data to be written to one or more storage disks. The system generates a disk write pending indicator associated with each datum to be written to the one or more storage disks, for indicating that the data stored in the temporary memory must be written to disk. A disk director searches the temporary memory storage for data stored in the temporary memory storage that must be written to disk as indicated by the associated data write pending indicator, for writing the data to the one or more storage disks. Also included are means for providing electrical power to the one or more storage disks, the temporary memory storage and the disk director upon the failure of main electrical power, for assuring completion of write commands stored in the temporary memory storage to one or more storage disks upon the failure of main electrical power.

摘要： A reconfigurable, multi-function data controller for use in a data storage system is selectively adaptable for use as a data channel adapter or a storage device adapter. The controller includes a data channel interface having at least one independent, bi-directional channel interface, for transmitting and receiving commands, data and status with one or more host computers. At least one memory interface transmits and receives commands and data to and from at least one high speed semiconductor memory unit. Additionally, a data storage interface controls and transmits data to and from one or more data storage devices such as a disk drive. A multi-function controller director is coupled to the data channel interface, the at least one memory interface, and the data storage device interface, for directing the reconfigurable multi-function data controller to function as either a data channel adapter or as a storage device adapter in response to selected commands received by the director.
