Abstract: A storage system and related method are for operating solid-state storage memory in a storage system. Zones of solid-state storage memory are provided. Each zone includes a portion of the solid-state storage memory. The zone has a data write requirement for the zone for reliability of data reads. The storage system adjusts power loss protection for at least one zone. The adjusting is based on the data write requirement for the zone and responsive to detecting a power loss.

Abstract: Storage layer data obfuscation, including: determining a subset of a dataset to obfuscate in accordance with a security policy; generating, based at least in part on the security policy, an obfuscated snapshot of the dataset that is representative of the dataset with the subset of the dataset obfuscated; and sending, to a target computer system, the obfuscated snapshot from which a restored version of the dataset includes the subset of the dataset obfuscated.

Abstract: Establishing a synchronous replication relationship between two or more storage systems, including: identifying, for a dataset, a plurality of storage systems across which the dataset will be synchronously replicated; configuring one or more data communications links between each of the plurality of storage systems to be used for synchronously replicating the dataset; exchanging, between the plurality of storage systems, timing information for at least one of the plurality of storage systems; and establishing, in dependence upon the timing information for at least one of the plurality of storage systems, a synchronous replication lease, the synchronous replication lease identifying a period of time during which the synchronous replication relationship is valid.

Abstract: A method for migration of data is provided. The method includes triggering a rebuild of data according to a first migration mechanism from a first storage drive to a second storage drive. Monitoring space utilization associated with the second storage drive, and adaptively switching the migration of the data from the first migration mechanism to a second migration mechanism based on the monitoring.

Abstract: Deduplicating data based on recently reading the data, including: determining whether a calculated signature for write data matches a particular signature corresponding to data that was recently read from the storage device, wherein the signature is calculated using the write data as input; and after determining that the calculated signature for the write data matches the particular signature, obtaining the data that was recently read and comparing the data that was recently read to the write data.

Abstract: Determining active membership among storage systems synchronously replicating a dataset, where determining active membership includes: detecting, by a particular storage system of the storage systems, a communication fault with one or more of the storage systems, where the particular storage system is configured to request mediation from a mediation target; determining that at least one of the one or more storage systems is configured to request mediation from the mediation target responsive to the communication fault; and responsive to determining that one or more of the storage systems is configured to request mediation from the mediation target, determining whether to request mediation from the mediation target.

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 plurality of storage nodes is provided. The plurality of storage nodes includes a first plurality of storage nodes configured to communicate together as a first storage cluster and a second plurality of storage nodes configured to communicate together as a second storage cluster. Each of the first and second pluralities of storage nodes has nonvolatile solid-state memory for user data storage and each of the first and second pluralities of storage nodes is configured to distribute user data and metadata associated with the user data throughout a respective plurality of storage nodes such that a respective storage cluster maintains ability to read the user data, using erasure coding, despite a loss of one or more of the respective plurality of storage nodes.

Abstract: An illustrative method includes detecting a request to perform an overwrite operation with respect to a non-header portion of a file stored by a storage system and determining, based on the detecting the request, that data stored by the storage system is possibly being targeted by a security threat.
