Abstract: Transitioning between replication sources for data replication operations, including: delaying a transition from using a first data repository as a source for data replication to using a second data repository as the source for data replication after detecting that one or more storage operations directed to the first data repository have not been replicated to the second data repository; and promoting the second data repository as the source for data replication such that storage operations received after completing the transition are directed to the second data repository.

Abstract: Modifying a synchronously replicated dataset, including: receiving, by a leader storage system, a request to modify a dataset that is synchronized across a plurality of storage systems; sending, from the leader storage system to a follower storage system, information describing the request to modify the dataset, wherein the leader storage system and the follower storage system each store a copy of the dataset; processing, by the leader storage system on the copy of the dataset that is stored on the leader storage system, the request to modify the dataset; receiving, from the follower storage system, an indication that the follower storage system has processed the request to modify the dataset on the copy of the dataset that is stored on the follower storage system; and acknowledging, by the leader storage system, completion of the request to modify the dataset.

Abstract: A pod, the pod including the dataset, a set of managed objects and management operations, a set of access operations to modify or read the dataset, and a plurality of storage systems, where: management operations can modify or query managed objects equivalently through any of the storage systems, access operations to read or modify the dataset operate equivalently through any of the storage systems, each storage system stores a separate copy of the dataset as a proper subset of the datasets stored and advertised for use by the storage system, and operations to modify managed objects or the dataset performed and completed through any one storage system are reflected in subsequent management objects to query the pod or subsequent access operations to read the dataset.

Abstract: Verifying that data has been correctly replicated to a replication target, including: replicating a dataset stored at a first computing system to a second computing system; and determining, based at least on a comparison of a first hash and a second hash, validity of the dataset stored at the second computing system, wherein the first hash is generated by applying a hash function to a copy of the dataset that is stored at the first computing system and the second hash is generated by applying the hash function to a copy of the dataset that is stored at the second computing system.

Abstract: Optimizing copy operations in a storage array, includes combining, in dependence upon a metadata optimization policy, a plurality of copy operations into a single copy operation and splitting the single copy operation into an optimized set of executable copy operations that copy data based on memory alignment.

Abstract: A storage system switching mediators within a storage system synchronously replicating data, where the switching between mediators includes determining that availability of a first mediator service has decreased to a particular level, wherein the first mediator service can provide mediation services at the particular level to a plurality of storage systems and is external to the plurality of storage systems; and based on the determination, switching from use of the first mediator service to use of a second mediator service that is external to the plurality of storage systems.

Abstract: A storage system switching between mediation models within a storage system, where the switching between mediation models includes: determining, among one or more of the plurality of storage systems, a change in availability of a mediator service, wherein one or more of the plurality of storage systems are configured to request mediation from the mediator service in response to a fault; and communicating, among the plurality of storage systems and responsive to determining the change in availability of the mediator service, a fault response model to be used as an alternate to the mediator service among one or more of the plurality of storage systems.
