Abstract: Data spillover for storage arrays, including: entering, by a source storage array, in response to determining that an amount of used capacity for the source storage array exceeds a first threshold, a spillover mode; redirecting, in response to the source storage array being in the spillover mode, write operations directed to the source storage array to a target storage array; and exiting the spillover mode by the source storage array, wherein exiting the spillover mode comprises updating data stored on the source storage array to reflect write operations redirected to the target storage array during the spillover mode.

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: One or more indications that input/output (I/O) operations have been performed by a storage system are received from the storage system. An amount of energy consumed by the storage system to perform the I/O operations id determined. An energy usage effectiveness of the storage system is generated based on a number of the I/O operations performed by the storage system and the amount of power consumed by the storage system to perform the plurality of I/O operations.

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: Write requests to store data at one or more solid-state storage devices are received by a storage controller from clients external to a storage system. A number of open segments in the storage system is identified. A determination as to whether to open one or more subsequent segments for the write requests is made based on the number of open segments and a target parallelism for the storage system. In response to determining that the one or more subsequent segments are to be opened based on the number of open segments and the target parallelism, the one or more subsequent segments are opened.

Abstract: A storage system is provided. The storage system includes a primary storage node comprising a primary processing device and a first set of non-volatile memory modules. The storage system also includes a secondary storage node comprising a secondary processing device a second set of non-volatile memory modules, the second storage node communicatively coupled to the primary storage node, the secondary storage node performs storage operations based on instructions received from the primary storage node. The primary processing device is to receive a request to access one or more of the first set of non-volatile memory modules and the second set of non-volatile memory modules and transmit instructions to perform a set of storage operations to the secondary storage node based on the request.

Abstract: Providing application-side infrastructure to control cross-region replicated object stores is disclosed. An embodiment includes determining, for an object store replicated across a plurality of storage systems at a plurality of locations, a minimum time interval between requests to modify the object store that are received by differing storage systems of the plurality of storage systems that ensures a predictable result on all storage systems among which the requested modifications are replicated; and providing, through an application programming interface (API) to a client that utilizes the object store, one or more object store parameters including the minimum time interval.
