Apparatus and method for processing input/output completion of storage device

Abstract

The present disclosure relates to an apparatus and a method for processing input/output completion of a storage device. The apparatus includes: an input/output command generation unit that generates an input/output command for the storage device: an input/output completion checking method determination unit that provides an input/output request to the storage device based on the input/output command and determines an input/output completion checking method for the storage device; and an input/output completion determination unit that performs an input/output checking procedure according to the input/output completion checking method and determines whether the input/output command is completed. Therefore, the present disclosure may dynamically switch to the most advantageous technique for detecting I/O completion of the storage device, depending on CPU contention arising from CPU sharing of an I/O request process, and may improve I/O performance by quickly detecting the I/O completion of the storage device.
