US Patent 8676851 Executing transactions in distributed storage systems

A method of executing a transaction in a distributed storage system includes, for data chunks of a read set of the transaction, reading data of the data chunks of the read set through remote direct memory access and determining a validity of the read data by evaluating a version and a lock of each data chunk of the read set. For data chunks of a write set of the transaction, the method includes setting locks on the data chunks of the write set, writing data to the locked data chunks through remote direct memory access, releasing the locks of the locked data chunks, and incrementing a version number of each released data chunk.
