Abstract
A system and method for clients, a control module, and storage modules to participate in a unifed address space in order to and read and write data efficiently using direct-memory access. The method for reading data includes determining a first location in a first memory to write a first copy of the data, a second location in a second memory to write a second copy of the data, where the first memory is located in a first storage module including a first persistent storage and the second memory is located in a second storage module including a second persistent storage. The method further includes programming a direct memory access engine to read the data from the client memory and issue a first write request to a multicast address, where the first location, the second location, and a third location are associated with the multicast address.
