singleton - cache memory - management protocol for hierarchical virtualised storage systems

摘要

Methods and arrangements for providing a cache memory - management in a hierarchical virtualized storage system. In consideration of a towed the method comprises: determining a relative position for each layer in the memory system in relation to at least one other layer in the memory system; giving an between storage directive, the jointly on all the layers is to be applied, wherein the between the storage of directive on the relative position of each layer in relation to at least one other layer is based in the storage system; and maintaining of the data transmission between the layers in the case of a test of the crosses of data in at least one of the layers, to the use of the directive between storage to permit. Other variants and embodiments are generally considered.
