Abstract
A method that enables user space middleware or applications to pass I/O storage requests directly to a network attached storage device via a storage server that performs authentication is provided. A mechanism is provided for using a translation protection table (TPT) data structure, which may include a file name protection table (FNPT) and file extension protection table (FEPT), or logical volume protection table (LVPT), to control user space and out of user space Input/Output (I/O) operations. The storage server performs authentication of an application instance's request to open an operating system logical volume and, upon being authenticated, permits the application instance to submit I/O storage requests via the TPT to the opened OS logical volume. I/O storage requests are translated into storage commands using the TPT and the storage commands are encapsulated for transmission via one or more networks to the storage server.
