Direct Access File System

Direct Access File System (DAFS) is a network file system that is based on NFSv4 and the Virtual Interface (VI) data transfer mechanism. DAFS uses remote direct memory access (RDMA) to perform efficient network access to data in remote files. This lowers latency by reducing the number of steps needed to process and transfer remote data. File locking is cached on the client side, eliminating the need to access the file server for subsequent data access.
