MASSIVE CONTROLLER, SOLID STATE DISK AND DATA RECORDING SOLID STATE DISK CONTROL METHOD

摘要

Embodiments of the present invention provide an array controller, including a communications interface and a processor. The communications interface is configured to communicate with a solid state disk. The processor is configured to receive information about a logical block sent by the solid state disk, where the information about the logical block includes a size of the logical block and indication information of the logical block, and the logical block includes one or more blocks. The processor is further configured to send multiple write data requests to the solid state disk, where each write data request carries target data, each write data request is used to instruct the solid state disk to write the target data into the logical block indicated by the indication information of the logical block, and a sum of lengths of the target data carried in the multiple write data requests is equal to the size of the logical block. The logical block may be filled after the solid state disk writes each piece of target data to the logical block, which can reduce write amplification when the solid state disk performs a garbage collection operation.
