Abstract: Utilizing multiple redundancy schemes within a unified storage element, including: receiving, in a storage system at a unified storage element that integrates both fast durable storage and bulk durable storage, a data storage operation from a host computer; storing, in accordance with a first data resiliency technique that corresponds to a RAID N+R format, data corresponding to the data storage operation within the fast durable storage of the unified storage element; and responsive to determining that the complete RAID stripe has been written to the fast durable storage, moving a portion of the stored data from the fast durable storage to the bulk durable storage of the unified storage element, the bulk durable storage storing the data in accordance with a second data resiliency technique that corresponds to a RAID M+R format, wherein M is different from N.

Abstract: Data resiliency in a cloud-based storage system, including: receiving, for storage within a first tier of cloud storage of the cloud-based storage system, one or more segments of data; generating, for each of one or more shards of data of the one or more segments of data, self-describing information for recoverability of the one or more shards of data; and storing, within a second tier of cloud storage of the cloud-based storage system, both the one or more shards of data and the generated self-describing information for recoverability of the one or more shards of data.

Abstract: Continuous data protection, including sending, to a target data repository from a source data repository, metadata describing one or more updates to one or more datasets stored within the source data repository; generating, based on the metadata describing the one or more updates to the one or more datasets, an ordered log of metadata describing an ordered application of the one or more updates to the one or more datasets; and generating, on the source data repository and based on the ordered log of metadata, the one or more datasets in accordance with the one or more updates corresponding to a specified point in time.

Abstract: A storage system establishes a staging region, for temporary writing of arriving data, and a stable region, for transfer of data from the staging region, in storage memory. The storage system establishes resiliency groups, each with a characteristic level of redundancy that is settable on an individual basis. The storage system performs data accesses of data stripes in accordance with the staging region, the stable region, a first resiliency group and a second resiliency group.

Abstract: Continuing replication during storage system transportation, including: replicating, between a first storage system and a second storage system, a dataset; connecting, by the first storage system during movement of the first storage system to a new physical location, to a communication network available at one or more intermediate physical locations; and continuing the replicating of the dataset between the first storage system at one or more of the intermediate physical locations and the second storage system over the communication network available at one or more of the intermediate physical locations.

Abstract: Controlling the direction of replication between cross-region replicated object stores is disclosed. An embodiment includes receiving, from a first storage system by a second storage system, replicated objects of an object store serviced by the first storage system, wherein the first storage system and the second storage system are configured for replication of the object store, and wherein the second storage system is not configured to service requests to modify the object store; determining, by the second storage system, a minimum time interval for taking over service for from the first storage system, such that delaying takeover until reaching the minimum time interval ensures that modification requests received by the first storage system prior to a takeover are correctly ordered as being earlier than subsequent modification requests serviced by the second storage system subsequent to the takeover; identifying, by the second storage system, a trigger initiating a takeover of the service of the object store from the first storage system; and delaying, by the second storage system, a takeover of servicing requests to modify the object store by at least the minimum time interval.

Abstract: A read request with a high priority indication is received. A determination as to whether an in progress flash programming operation would delay processing the read request for a threshold amount of time is made. In response to determining that the in progress flash programming operation delays processing the read request for the threshold amount of time, the in progress flash programming operation is interrupted.

Abstract: A storage system has zones in solid-state storage memory, with power loss protection. The system identifies portions of data for processes that utilize power loss protection. The system determines to activate or deactivate power loss protection for the portions of data for the processes. The system tracks activation and deactivation of power loss protection in zones in the solid-state storage memory, in accordance with the portions of data having power loss protection activated or deactivated.

Abstract: Managing storage systems that are synchronously replicating a dataset, including: detecting a change in membership to the set of storage systems synchronously replicating the dataset; and applying one or more membership protocols to determine a new set of storage systems to synchronously replicate the dataset, wherein the one or more membership protocols include a quorum protocol, an external management protocol, or a racing protocol, and wherein one or more I/O operations directed to the dataset are applied to a new set of storage systems.
