DPFS adopts file mapping interface as its API, which is simpler than read/write interface. With file mapping interface, some features of the DSM system have been utilized to make the implementation of DPFS easier and the performance higher.

• DPFS系统采用文件映射接口作为应用编程接口 ；使得文件存取界面简单 ；并且能充分利用软件 DSM系统的大量特性 ；系统设计相对简单 .
