Abstract
There is provided a method and server for retrieving data from a data storage system including a plurality of storage nodes. The method may include sending a multicast message to at least a subset of the storage nodes. The multicast message may include a request for the subset of storage nodes to send the data. The multicast message may further include a data identifier, indicating the data to be retrieved. Moreover, the method may include receiving data from a first storage node of the subset of storage nodes. The data received from the first storage node may correspond to the requested data. At least the act of sending a multicast message or the act of receiving data from the first storage node may be performed on a condition that an estimated size of the data is less than a predetermined value.
