Abstract: According to one embodiment, a computer system includes a host computer, and a storage device coupled to the host computer. The host computer has a user-space device driver of the storage device in a user space of a host operating system (OS). The user-space device driver is configured to handle I/O operations to and from the storage device based on an application running on the host computer.

Abstract: A system and method for enabling an application (125, 305, 310, 315) and a storage device (120) to be more aware of each other may include a computer (105), a processor (110), and a memory (115) as well as the storage device (120). An application (125, 305, 310, 315) stored in the memory may communicate with a user space device driver (130). The user space device driver (130) may include a Mode Configure Module (320) to receive an application profile (405, 430, 435) from the application (125, 305, 310, 315) and an Application Aware Module (325) to receive I/O commands (555) from the application (125, 305, 310, 315) and place them in command queues (510, 515, 520, 525, 535, 540, 545, 550) according to the application profile (405, 430, and 435). The I/O commands (555) may then be sent to the storage device (120).
