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.
