    Abstract: Replication between virtual storage systems includes: constructing a virtual storage system in which the one or more virtual storage devices are coupled to each of one or more virtual storage controllers and replicating a dataset from the virtual storage system to another virtual storage system, where at least one of the virtual storage systems is an on-premises virtual storage system utilizing on-premises physical storage resources.

    Abstract: Recovering from system faults for replicated datasets, including: receiving, by the cloud-based storage system, a request to modify a dataset that is stored by the cloud-based storage system, wherein the dataset is synchronously replicated among a plurality of storage systems that includes the cloud-based storage system, wherein a request to modify the dataset is acknowledged as being complete when each of the plurality of storage systems has modified its copy of the dataset; generating recovery information indicating whether the request to modify the dataset has been applied on all storage systems in the plurality of storage systems synchronously replicating the dataset; and after a system fault, applying a recovery action in dependence upon the recovery information indicating whether the request to modify the dataset has been applied on all storage systems in the plurality of storage systems synchronously replicating the dataset.

    Abstract: A system and method for efficient use of zones in a storage system. The method includes: building a frontier set comprising one or more zones of one or more storage devices for writing to; writing data to at least one zone of the one or more zones included in the frontier set; and during a bootup sequence: accessing a frontier set list to identify the one or more zones in the frontier set; and scanning the one or more zones to identify the at least one zone that data was written to.

    Abstract: In a particular embodiment, a virtual namespace identifier is mapped to one or more volumes stored among a pool of storage resources, wherein at least a first storage system and a second storage system are utilized to provide the storage resources. The virtual namespace identifier is migrated among the pool of storage resources to virtualize a data path for the one or more volumes.

    Abstract: A storage system switching mediators within a storage system synchronously replicating data, where the switching between mediators includes: determining, among one or more of the plurality of storage systems, a change in availability of a first mediator service, wherein one or more of the plurality of storage systems are configured to request mediation from the first mediator service; communicating, among the plurality of storage systems and responsive to determining the change in availability of the first mediator service, a second mediator service to use in response to a fault; and switching, in dependence upon the change in availability of the first mediator service, from the first mediator service to the second mediator service.

    Abstract: Synchronously replicating a dataset across cloud-based storage systems, including adding a cloud-based storage system to a set of storage systems that the dataset is synchronously replicated across, where access operations are applied to the dataset equivalently through all storage systems in the set, all storage systems in the set store a separate copy of the dataset, and operations to modify the dataset performed and completed through any of the storage systems in the set are reflected in access operations to read the dataset, the cloud-based storage system including one or more cloud computing instances executing a storage controller application, a virtual drive layer that includes one or more cloud computing instances with local storage for storing at least a portion of the dataset as block data, and an object storage layer for storing at least a portion of the dataset as object data.
