Abstract: A system and method for efficient execution of I/O operations in a storage environment including receiving, by a storage controller, an incoming I/O operation that can be serviced by a storage device while at least one pending operation is to be processed using the storage device, determining, based on an analysis by the storage controller of an operational state of a storage system that includes the storage device, whether processing the at least one pending operation is more efficient than issuing an alternative operation to the storage device, and issuing, by the storage controller, one or more instructions to the storage device.

Abstract: Application-managed fault detection for cross-region replicated object stores is disclosed. An embodiment includes determining, by a first storage system among a plurality of storage systems replicating an object store, a faulted state in response to identifying a fault that prevents replication of updates to the object store to at least a second storage system of the plurality of storage systems; providing, through an API, an indication that the first storage system has entered the faulted state; and receiving a request indicating how to proceed in the presence of the fault.

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: Synchronizing metadata among storage systems synchronously replicating a dataset, where synchronizing the metadata includes: receiving, at a first storage system of the storage systems, an I/O operation directed to the dataset; determining, in dependence upon the I/O operation, a metadata update describing a mapping of segments of content to a virtual address within a storage object, wherein the storage object includes the dataset; and synchronizing metadata on a second storage system of the storage systems by sending the metadata update to the second storage system to update a metadata representation on the second storage system in accordance with the metadata update.

Abstract: Coordinated snapshots among storage systems implementing a promotion/demotion model, including monitoring a set of two or more target storage systems, wherein the two or more target storage systems are replication targets for respective portions of a source dataset; associating a first coordinated tracking dataset with two or more local tracking datasets maintained on the two or more target storage systems, wherein each local tracking dataset is a tracking copy for one portion of the source dataset; and advancing, in dependence upon a first coordinated target checkpoint, the first coordinated tracking dataset.

Abstract: Symmetric storage using a cloud-based storage system, including: receiving, at a cloud-based storage system among storage systems synchronously replicating a dataset, an I/O operation directed to the dataset; determining, in dependence upon the I/O operation, a metadata update describing a mapping of segments of content to an address within a storage object, wherein the storage object includes the dataset; and synchronizing metadata on another storage system of the storage systems by sending the metadata update from the cloud-based storage system to the other storage system to update a metadata representation on the second storage system in accordance with the metadata update.
