1. A method for storing data with replicated metadata in a scale-out data storage system, the method comprising:
receiving, by a first data storage node of the scale-out data storage system, a data item to be stored;
storing, by the first data storage node, the data item on a storage area network in communication with the scale-out data storage system;
storing a local copy of the data item on the first data storage node;
generating, by the first data storage node, a metadata item corresponding to the data item, wherein the metadata item includes a file name of the data item, a timestamp corresponding to the data item, and a storage location of the data item in the storage area network; and
replicating only the metadata item to a second data storage node of the scale-out data storage system, wherein the data item is not replicated to the second data storage node.
