Abstract: A coordinating node maintains globally consistent logical block address (LBA) metadata for a hierarchy of caches, which may be implemented in local and cloud based storage resources. Associated storage endpoints initially determine a hash associated with each access request, but forward the access request to the coordinating node to determine a unique discriminator for each hash.

Abstract: A coordinating node creates virtual storage from a hierarchy of local and remote cache storage resources by maintaining global logical block address (LBA) metadata maps. A size of the metadata maps at each level of the hierarchy is independent of an amount of data allocated to a respective cache store at each level.
