Abstract: A computer system includes a host and a storage device. The host provides an input/output request (IO request). The storage device receives the IO request from the host and sends an interrupt informing input/output completion (IO completion) to the host after completing the IO request. The host adjusts the number of generated interrupts of the storage device using the number of delayed IOs. The computer system may adaptively control interrupt generation of the storage device based on a load status of a CPU or the number of delayed IOs. The interrupt generation of the storage device may be adjusted to obtain a CPU gain without loss of performance or processing time of the computer system.

Abstract: Disclosed is a storage device which includes a nonvolatile memory device, and a controller configured to partition a storage space of the nonvolatile memory device into zones and access the storage space. Each zone corresponds to consecutive physical addresses of the nonvolatile memory device, and the controller is configured to map the consecutive physical addresses of each zone onto consecutive logical addresses. In response to a copy command being received from an external host device, the controller is configured to start a copy operation for copying data of a first zone of the zones to a second zone of the zones and send first read commands and first write commands to the nonvolatile memory device. In response to a suspend command, the controller is configured to suspend the copy operation, store progress status information about the copy operation, and send a suspend response to the external host device.
