摘要:
A system, method, and computer program product 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) are provided. 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 doorbell message and processing queue mechanism are provided for notifying the I/O adapter of work requests to be processed by the I/O adapter.
