US Patent 9164702 Single-sided distributed cache system

A distributed cache system including a data storage portion, a data control portion, and a cache logic portion in communication with the data storage and data control portions. The data storage portion includes memory hosts, each having non-transitory memory and a network interface controller in communication with the memory for servicing remote direct memory access requests. The data control portion includes a curator in communication with the memory hosts. The curator manages striping of data across the memory hosts. The cache logic portion executes at least one memory access request to implement a cache operation. In response to each memory access request, the curator provides the cache logic portion a file descriptor mapping data stripes and data stripe replications of a file on the memory hosts for remote direct memory access of the file on the memory hosts through the corresponding network interface controllers.
