Abstract
Replication of a storage object to a remote storage array is seamlessly maintained by i) while write operations directed to the storage object are being collected into a set of write cycles that are stored in a master storage array, also collecting the write operations directed to the storage volume into a set of write cycles stored in a slave storage array, and ii) in response to detecting a failure of the master storage array, and while the host computer continues to access the storage object using a copy of the storage object located in the slave storage array, transmitting the write cycles stored in the slave storage array to the remote storage array, so that the remote storage array can apply the write operations in the write cycles it receives from the slave storage array on the copy of the storage object contained in the remote storage array.
