Abstract: A computer-implemented method includes migrating an item to a cache cluster from a home cluster in a storage system in a cutover process and initiating a data validation process with the home cluster. The method includes enabling at least one tunable parameter on the item on the cache cluster in the storage system. The tunable parameter is configured to adjust the data validation process with the home cluster. The tunable parameter includes at least one condition. The method includes enabling at least one flag on the item on the cache cluster in the storage system. The flag is configured to indicate that the at least one condition of the tunable parameter on the item in the storage system is met. In response to the at least one condition of the tunable parameter being met, the method includes ending the data validation process with the home cluster in the storage system.

Abstract: A computer-implemented method, according to one embodiment, includes: receiving data replication operations from one or more compute nodes at a primary location, storing the received data replication operations in a queue, and dividing the queued data replication operations into a number of independent sub-groups. The number of independent sub-groups is equal to or less than a number of worker gateway nodes. Each of the independent sub-groups are further added to a respective one of the worker gateway nodes. One or more instructions are also sent to each of the worker gateway nodes to send the data replication operations included in the respective independent sub-group to a remote storage location. Other systems, methods, and computer program products are described in additional embodiments.
