Replication techniques are presented. According to an embodiment of a method, a node of a replicated storage network is assigned to be an owner of a data block to issue write memory block commands. The network includes at least two nodes including the node assigned to be the owner. If a read memory block command is received to read the data block, a read_lock is issued for the data block, the data block is read, and the read_lock for the data block is released. If a write memory block command is received to write new data to the data block, a write_lock is issued for the data block, the data block is written and a version associated with the data block is incremented, and the write_lock for the data block is released.
