Asynchronous IO data processing method, device and equipment and medium

The invention discloses an asynchronous IO data processing method, device and equipment, and a computer readable storage medium. The method comprises the steps: receiving an asynchronous IO data storage request; obtaining label information of each asynchronous IO data segment, storing the label information in a pre-created data label storage pool, and storing the asynchronous IO data segments inthe data pool; when an asynchronous IO data reading request is received, obtaining an object name of the asynchronous IO data reading request; and obtaining all label information corresponding to theobject name of the asynchronous IO data storage request in a data label storage pool, and reading asynchronous IO data corresponding to the asynchronous IO data reading request according to the offsetof the asynchronous IO data segment in the label information and the storage position of the asynchronous IO data segment. According to the scheme disclosed by the invention, the asynchronous IO datafragments with wrong sequenc
