The invention relates to a distributed high-performance database all-in-one machine system which comprises a database all-in-one machine and an auxiliary module configured in the database all-in-one machine. The database all-in-one machine comprises a user host, an Oracle application host, a storage device and a data storage network, wherein the user host is used for business processing, the Oracle application host returns a processing result to the user host, the storage device stores data needed by the user host, and the data storage network is connected with the Oracle application host and the storage device. The auxiliary module comprises a storage device management module, a distributed high-performance intelligent storage module and an Oracle host adaption module, wherein the storage device management module is used to schedule the storage device in a unified manner, the distributed high-performance intelligent storage module communicates with the storage device management module to realize distributed high-performance intelligent storage of the storage device, and the Oracle host adaption module is used to map the storage device into a standard storage hardware resource. Compared with the prior art, the distributed high-performance database all-in-one machine system has the advantages of large processing data bulk, high processing speed, high processing performance and high reliability.
