摘要： A digital data storage system comprising a mass storage subsystem in which information is stored on one or more disk storage units, with a storage element constituting a track on a disk storage device and each track storing a plurality of records. Each track in each disk storage device of the digital data storage system is associated with a descriptor. In that embodiment, when the control device retrieves the contents of a record, it can use the format definition type identifier of the descriptor associated with the track to determine the format definition type for the track, use the specific format information to determine the location and size of the record on the track, and retrieve the record. Similarly, if the record is to be updated, the control device can use the format definition type identifier of the descriptor associated with the track to determine the format definition type for the trap, use the specific format information to determine the location and size of the record on the track, and update the record on the track. A number of format definition types are disclosed.

摘要： A cache management system and method monitors and controls the contents of cache memory. A time indication provider provides a time indication signal to a cache indexer, for maintaining a cache index which are stored in cache as well as an indication that a data element must be written to a longer term data storage device. A cache manager is responsible for placing data elements into and removing data elements from the cache memory. The cache manager is responsive to at least one data element stored in cache which must be written to a longer term data storage device, and to the associated time indication, for determining the amount of time that the data element has been stored in cache as well as the average period of time that elapses between a data element being inserted in cache and being removed from cache. Based on a comparison of the average period of time that elapses between a data element being entered into and removed from cache and the amount of time that the data element which is written to a longer term data storage device has been stored in cache, the cache manager determines whether to place the data element in the top of the cache, to allow the data element to remain in cache a longer period of time, or at the bottom of the cache which will cause the date element to be removed from cache more quickly.

摘要： A dynamic cache management system and method monitors and controls the contents of cache memory coupled to at least one host and at least one data storage device. A cache indexer maintains a current index of data elements which are stored in cache memory along with a time indication which relates to each data elements use in the cache. A sequential data access indicator, responsive to the cache index, to the time indication associated with each data element and to a user selectable data access threshold, determines that a sequential data access is in progress for a given process and provides an indication of the same. The system and method allocate a micro-cache memory to any process performing a sequential data access. In response to the indication of a sequential data access in progress and to a user selectable maximum number of data elements to be prefetched, a data retrieval requestor requests retrieval of up to the selected maximum number of data elements from a data storage device. A user selectable number of sequential data elements determines when previously used micro-cache memory locations will be overwritten.
