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.
