METHOD FOR ENSURING MAP INTEGRITY IN A SYSTEM-MANAGED STORE OF A COMPUTER
摘要
<p>A method for dynamically detecting loss of map integrity in a form of system-managed storage (SMS). In SMS, maps are used to define access paths to data and to allocate and reallocate storage resources among applications running thereon. The method steps include incorporating as an indivisible part of an overwriting commmand the duplication of map information by appending a portion of it to each data block in store, and detecting loss of map integrity as a function of a comparison mismatch between the portion stored with a counterpart data block and the map upon each read/write access.</p>
