    Abstract: A storage device includes at least one nonvolatile memory device; and a memory controller configured to control the nonvolatile memory device, wherein the memory controller includes, at least one processor configured to control an overall operation of the memory controller; a buffer memory configured to store input/output data according to a control of the processor when an input/output request from an external device occurs; an error correction circuit configured to detect and correct an error of the input/output data; a garbage collector configured to selectively generate a first global garbage collection command in response to the input/output request and configured to perform a global garbage collection according to a second global garbage collection command received from the external device; and a storage interface configured to transmit the first global garbage collection command to another storage device.

    Abstract: A storage device includes a nonvolatile memory device including a storage space, and a controller that is configured to divide and manage the storage space of the nonvolatile memory device into a user area and a meta area and to provide access to the user area to a host device. Responsive to receiving Redundant Array of Inexpensive Disks (RAID) spare information from the host device, the controller is further configure to select a RAID spare area from the user area based on the RAID spare information and to use at least a portion of the RAID spare area as an over provision area.

    Abstract: A input/output method is disclosed for performing communications in a virtual machine (VM) environment between a host operating system (OS) and a guest OS. The input/output method includes performing request polling (RP) on an input/output event generated by a guest OS which is driven by a virtual machine (VM), sending an input/output request to a host OS, on which the VM runs. The input/output method further includes performing response waiting polling (RWP) on an input/output completion message generated by the host OS when the input/output event is detected through the RP, and sending an input/output response to the guest OS when the input/output completion message is detected through the RWP. In the method, the RP and the RWP are performed by multiple threads executed on the VM.
