摘要： The present invention relates to a distributed data storage system comprising a plurality of storage nodes. Using unicast and multicast transmission, a server application may write data in the storage system. When writing data, at least two storage nodes are selected based in part on a randomized function, which ensures that data is sufficiently spread to provide efficient and reliable replication of data in case a storage node malfunctions.

摘要： The present invention relates to a distributed data storage system comprising a plurality of storage nodes. Using unicast and multicast transmission, a server application may read and write data in the storage system. Each storage node may monitor reading and writing operations on the system as well as the status of other storage nodes. In this way, the storage nodes may detect a need for replication of files on the system, and may carry out a replication process that serves to maintain a storage of a sufficient number of copies of files with correct versions at geographically diverse locations.

摘要： A method for maintaining a data storage system is disclosed. The method may include monitoring a first data storage node. The method may also include detecting a condition regarding the first data storage node, and the condition may indicate that at least one file stored on the first data storage node is to be replicated. The method may also include updating a replication list based on detecting the condition, and the replication list may include an identification of the at least one file and priority information for replication of the at least one file. The method may include performing a data replication procedure based on the replication list, where the data replication procedure may include sending a first multicast message to a plurality of other data storage nodes requesting identification of a second data storage node that maintains a copy of the at least one file.
