Abstract:
A mechanism is provided that enables user space middleware or applications to pass file name based storage requests directly to a physical I/O Adapter without run-time involvement from the local Operating System (OS). A mechanism is provided for using a file protection table (FPT) data structure, which may include a file name protection table (FNPT) and file extension protection table (FEPT), to control user space and out of user space Input/Output (I/O) operations. In addition, a mechanism is provided for managing the FPT based on user space operations to create, query, modify and delete entries in the FPT.
