1. An apparatus comprising:

  • a burst buffer appliance adapted for coupling between a computer system and a file system;

    the burst buffer appliance comprising a high-speed memory having a substantially lower access time than the file system;

    the burst buffer appliance being configured to include a plurality of virtual machines for processing respective different types of input-output operations that involve utilization of the high-speed memory;

    wherein each of the virtual machines provides a different performance level for its associated type of input-output operations;

    wherein the plurality of virtual machines comprises;

    a first virtual machine for processing a first type of input-output operations that involve utilization of the high-speed memory; and

    at least a second virtual machine for processing at least a second type of input-output operations that involve utilization of the high-speed memory;

    wherein the first type of input-output operations is associated with a first priority and the second type of input-output operations is associated with a second priority lower than the first priority;

    wherein the first type of input-output operations comprises operations involving writing checkpoints from the computer system to the high-speed memory; and

    wherein the second type of input-output operations comprises operations involving at least one of;

    writing sensor data from a sensor network to the high-speed memory;

    writing or reading analytic engine data to or from the high-speed memory; and

    writing from the high-speed memory to the file system.
