Controlling access in a single-sided distributed storage system

Abstract

A distributed storage system that includes memory hosts having non-transitory memory storing data chunks of files. Each data chunk is associated with an access control list. Each memory host also includes a network interface controller in communication with the memory for servicing remote direct memory access requests and a computing processor in communication with the memory and the network interface controller. The computing processor executes a host process that registers a set of remote direct memory accessible regions of the memory storing data chunks with the network interface controller. In response to receiving a connection request from a client process of a client to access a data chunk, the host process establishes a remote direct memory access capable connection with the client process when both the client and the data chunk are associated with the same access control list.
