Abstract: A clustered storage system includes a plurality of storage devices, each of which contributes a portion of its memory to form a global cache of the clustered storage system that is accessible by the plurality of storage devices. Cache metadata for accessing the global cache may be organized in a multi-layered structure. In one embodiment, multi-layered structure has a first layer first including a first address array, and the first address array include addresses pointing to a plurality of second address arrays in a second layer. Each second address array in the second layer includes addresses, each of which points to data that has been cached in the global cache.
