Abstract: Embodiments of the present invention are directed to a system for exchanging data utilizing Remote Direct Memory Access. In response to a system call, a Network File System component generates a file request. An External Data Representation component formats the file request and passes the request to a Remote Procedure Call component which initiates the file request with a remote computer system. The Remote Procedure Call is passed to a unifying layer which communicates the the Remote Procedure Call to various transport layer Remote Direct Memory Access implementations. The various Remote Direct Memory Access implementations are used to exchange the data in order to communicate the file request.
