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.

Abstract: Maintaining a synchronous replication relationship between two or more storage systems, including: receiving, by at least one of a plurality of storage systems across which a dataset will be synchronously replicated, timing information for at least one of the plurality of storage systems; and establishing, based on the timing information, a synchronous replication lease describing a period of time during which the synchronous replication relationship is valid, wherein a request to modify the dataset may only be acknowledged after a copy of the dataset has been modified on each of the storage systems.

Abstract: A system and method for exposing volumes with underlying read-write mediums to user operations. When a medium is in the process of being migrated to a storage array, a volume which relies on the medium can be exposed to user operations (e.g., snapshots, read and write operations) once the portions of the medium which underlie the volume have been migrated. The volume can be exposed to user operations while one or more other portions of the medium are unfilled and while the medium is in an intermediate read-write state.

Abstract: Determining active membership among a set of storage systems synchronously replicating a dataset, where determining active membership includes: determining that a membership event corresponds to a change in membership to the set of storage systems synchronously replicating the dataset; applying, in dependence upon the membership event, one or more membership protocols to determine a new set of storage systems to synchronously replicate the dataset; and for one or more I/O operations directed to the dataset, applying the one or more I/O operations to the dataset synchronously replicated by the new set of storage systems.

Abstract: A storage system asynchronously replicating a synchronously replicated dataset, where the asynchronous replication of the asynchronously replicated dataset includes: determining, at a target storage system, multiple work items corresponding to a dataset stored among multiple source storage systems, wherein each respective work item corresponds to a respective subset of the dataset; and for each session from among a plurality of sessions operating on the target storage system: determining one or more computing environment factors affecting performance of replication of data from one or more of the multiple source storage systems to the target storage system; identifying, for a given session and based on the one or more computing environment factors, a respective source storage system and a quantity of work items; and replicating, from the respective storage system, one or more subsets of data corresponding to the quantity of work items.

Abstract: Prioritizing highly performant storage systems for servicing a synchronously replicated dataset: detecting a communication fault between two or more storage systems that are synchronously replicating a dataset; identifying a preferred storage system for winning mediation, including determining that the preferred storage system winning mediation would result in better performance than other storage systems winning mediation; and requesting, by the preferred storage system, mediation from a mediation target.

Abstract: Methods and systems for transitioning a replica of a file system are described. An illustrative method includes updating a replica file system on a target data repository to be a replica of a source file system as the source file system existed on the source data repository at a point in time, where the replica file system is constructed of block objects at the target data repository that store metadata for individual files and directories of the replica file system and support access to blocks of data associated with the files and directories of the target file system at the target data repository, and where the updating includes updating the block objects of the replica file system to be replicas of block objects of the source file system as the block objects of the source file system existed on the source data repository at the point in time.

Abstract: Implementing guardrails for non-disruptive migration of workloads between storage arrays, the method comprising: initiating a non-disruptive migration of one or more workloads from a source storage array to a target storage array; validating, prior to completion of the non-disruptive migration, accessibility of the target storage array by one or more hosts; and completing, based on successfully validating the accessibility of the target storage array, the non-disruptive migration.
