摘要
The subject matter of this specification can be implemented in, among other things, a method that includes pre-registering, by a processing device at a client device, multiple input/output (IO) buffers at the client device with a remote direct memory access (RDMA) interface at the client device. The client device accesses multiple server devices of a distributed file system using the RDMA interface. The method further includes receiving a request to access a file in the distributed file system from an application at the client device. The method further includes designating a first IO buffer among the IO buffers as a cache for data from the file. The method further includes receiving the data for the file in the first IO buffer from the distributed file system using the RDMA interface.
