The invention relates to an initial parameter configuration method of a distributed storage system, and belongs to the technical field of computer database management. The initial parameter configuration method, which is divided into three stages including a training stage, a using stage and a dynamic updating stage, comprises the steps of firstly performing the training stage by a user to obtain a performance model; then solving an initial parameter configuration problem of the distributed storage system by using the performance model in the using stage; and then performing dynamic updating for the performance model based on feedback of the user in the dynamic updating stage. The initial parameter configuration method of the distribute storage system can efficiently avoid a cold-start problem of a traditional database and a traditional parameter adjusting tool, reduces hardware cost as much as possible under the precondition of meeting user demands, improves the system performance and brings about higher cost performance for the user.
