摘要:
In distributed storage environments (e.g., VPLEX®, from EMC Corporation) a director may be added while the distributed data is being replicated. However, the new director may have new splitters that do not know what to replicate and how to handle new I/Os. If I/Os are missed or lost, that information is gone forever and may be recovered only by a full resync of the volume. However, example embodiments of the present invention overcome these and other deficiencies by allowing adding a director and new splitters without interruption of the replication. Example embodiments of the present invention provide a method, an apparatus and a computer-program product for adding a director to storage with network-based replication without data resynchronization. The method includes obtaining distributed storage system node configuration information and performing replication in a network-based replication system according to the configuration information.
