Abstract: Embodiments of the present disclosure provide a method, apparatus, device, and storage medium for processing an access request, and relate to the field of cloud computing. The method includes: acquiring a plurality of to-be-distributed access requests for a storage device, the access requests at least including a group of read requests and a group of write requests; distributing read requests of the group of read requests to a drive device of the storage device without distributing a write request of the group of write requests, until a number of distributed read requests reaches a total number of read requests of the group of read requests or a first threshold number, the drive device being configured to execute the distributed requests on the storage device; and distributing at least one write request of the group of write requests to the drive device.

Abstract: Embodiments of the present disclosure provide a method, apparatus, device, and computer readable storage medium for processing data, and relate to the field of cloud computing. The method for processing data includes receiving a request for storing a data block from a virtual storage of a virtual machine into a virtual disk of the virtual machine, the request indicating a virtual storage address for storing the data block in the virtual storage and a virtual disk address for storing the data block in the virtual disk. The method further includes determining a physical storage address for storing the data block within a physical storage associated with the virtual machine based on the virtual storage address. The method further includes associatively storing the virtual disk address and the physical storage address.
