Abstract: System and methods for managing I/O throughput for large scale computing systems are provided. In one embodiment, an operating system for a computer system having a processor, a memory and at least one data storage device is provided. The operating system comprises: an operating system kernel; at least one filesystem controlling access to the at least one data storage device; and a toolkit module installed within the operating system kernel. The toolkit module monitors input/output (I/O) calls communicated via a datapath between at least one software application being executed on the processor and the filesystem. The toolkit module inserts one or more tools into the datapath, the one or more tools each executing a predefined function based on observation of a first set of the I/O calls being communicated in the datapath.
