CACHE ARCHITECTURE AND ALGORITHMS FOR HYBRID OBJECT STORAGE DEVICES

A method for data storage in a hybrid storage node of a data storage system is provided. The hybrid storage node includes first and second storage devices having different performance characteristics wherein the first devices includes at least one high performance non-volatile memory for cache storage. The hybrid storage node further includes processing resources for managing data storage in the hybrid storage node. The method includes receiving a read request to read stored information from the hybrid storage node and, in response to the read request, accessing both the cache storage first storage devices and storage in the second storage devices to locate the stored information.
