Abstract:
A mechanism is provided in a data processing system comprising at least one processor and at least one memory, the at least one memory comprising instructions that are executed by the at least one processor and configure the at least one processor to implement a replication protocol for replicating memory from an initiator to a target. The initiator requests one or more pages of memory at the target. Responsive to the initiator receiving a page advertisement from the target, the initiator updates a list of pages at the initiator. The list of pages is replicated at the target. The initiator performs a remote direct memory access (RDMA) write to the one or more pages of memory at the target. Responsive to successful completion of the RDMA write, the initiator updates the list of pages at the initiator. Upon completion of the RDMA write the list of pages is updated at the target.
