I researched a lot about storage system classes given at good universities this year. This had two reasons: The first was thispost of a researcher at NetApp, about the missing of a good storage or file system class book and secondly our own storage s…

A mechanism is provided in a data processing system for reliable asynchronous solid-state device based de-duplication. Responsive to receiving a write request to write data to the file system, the mechanism sends the write request to the file system,…
