A processing method and device for a flush magnetic disk input and output request. By determining whether a landed flush magnetic disk input and output request satisfies a pre-set condition and comparing an identification number of a landed magnetic disk input and output request with an identification number of a last flush magnetic disk input and output request, a flush magnetic disk input and output request can be rapidly processed according to a determination result, a CPU can be efficiently used, and in the case where a large amount of magnetic disk write input and output requests and flush magnetic disk input and output requests are concurrent in a cache existence scenario, the flush magnetic disk input and output requests and magnetic disk write input and output requests can still be efficiently processed, thereby realizing that a magnetic disk input and output request processing module efficiently processes flush magnetic disk input and output requests with low power consumption. |
