ARRAY CONTROLLER SOLID STATE DISK AND METHOD FOR CONTROLLING SOLID STATE DISK TO WRITE DATA

摘要

Embodiments of the present invention provide an array controller that includes a communication interface and a processor. The communication interface is configured to communicate with a solid state disk. The processor is configured to receive information regarding a logical block transmitted by a solid state disk, wherein the information about the logical block includes the size of the logical block and indication information of the logical block, wherein the logical block is one or more. Contains a block. The processor is further configured to send a plurality of write data requests to the solid state disk, each data write request carrying target data, each data write request to the solid state disk, The sum of the lengths of the target data included in the plurality of data write requests is used to instruct to write the target data to the logical block indicated by the indication information of the logical block, and the same as the size of the logical block. After the solid state disk writes each target data to the logical block, the logical block can be filled, thereby reducing write amplification when the solid state disk performs a garbage collection operation. Can be.
