DataMeshTM — scope and objectives : a commentary

A DataMesh can be viewed equally well as a storage server with a lot of local processing power, or as a highly-parallel computer with embedded storage. A physical manifestation might be as a wall-sized array of storage/processor nodes (discs, optical drives, pageaddressable RAM, etc) linked together by a web-like interconnect. Such a thing would live in the basement, and serve the storage needs of an enterprise of tens to hundreds of people. A DataMesh will: • scale to large amounts of secondary storage; • use processor and storage parallelism to deliver high performance; • use processor parallelism to provide higher functionality than traditional storage servers.
