Data storage using a cache and method therefor
摘要:
Data in pages is mapped into a very large virtual external address space (25) through a cache without disturbing the logical view of the data and without having to assign physical or real backing store to said logical view. A data cache (27) is used in which pages are indexed according to a logical address (23) intermediate to their virtual address and their physical location in external storage (5). Pages common to two or more files are updated in place in the cache, while pages bound to only one file are shadow copied.
