ABSTRACT:
The cache memory is divided into a plurality of slots, each of which is used to store data files that are staged from the storage devices for transmission to the processor or received from the processor for writing on the storage devices. The management of the plurality of slots is accomplished by the use of at least two sets of lists: global lists and local lists. These lists function to respectively manage the entirety of the cache memory and the slots, either on an individual slot basis or on a virtual device basis. These two sets of lists therefore operate on a substantially orthogonal basis, while also operating cooperatively, to efficiently manage the writing of data into and out of the cache memory.
