Provided are a computer-implemented method, system, and computer program product for multidimensional data recover. A snapshot restore request is received with at least one parameter defining at least one dimension for data recovery. At least one snapshot is reconstructed from a single continuous snapshot stream taken for a certain period of time based on the at least one parameter. A selected snapshot is received for data recovery selected from the at least one reconstructed snapshot. The selected snapshot is restored.

Multi-dimensional data recovery

A system may include a cluster and a module of the cluster. The module may include a user resource definition and a catalog server. The catalog server may maintain a configuration of the cluster.

Open-source container cluster hot plug adapter

The example embodiments disclose a system and method, a computer program product, and a computer system for improving solid-state drive performance. The example embodiments may include generating, by an affinity adapter located external to the solid-state drive, a plurality of affinities for each of a plurality of data to a respective plurality of subdivisions of data of a solid-state drive, wherein each of the plurality of data is associated with a logical block address (LBA) and each of the respective plurality of subdivisions has a physical block address (PBA). The example embodiments may also include receiving a request to write first data having a first LBA to the solid-state drive, determining by the solid-state drive, at a first time, that the first data has an affinity with a particular subdivision of data of a solid-state drive based on the generated plurality of affinities, and writing the first data to a memory location of the solid-state drive, wherein the PBA of the memory location has the determined affinity.

Solid-state drive performance and lifespan based on data affinity

In an approach to intelligently choosing transport channels across protocols by drive type, one or more transport channels on a host are detected. One or more storage drive tiers on a target are detected. The one or more transport channels are mapped to the one or more storage drive tiers, based on performance. A transfer of a data between a host and the target is completed, using each transport channel and each storage drive tier.

Intelligently choosing transport channels across protocols by drive type

Methods that can offload data operations to a storage system are provided. One method includes performing, by a processor, a set of non-storage operations at a storage system for data stored in a set of storage devices on the storage system to generate a set of results, in which the storage system is separate from a client device that owns the data, and transmitting the result(s) to the client device that owns the data. Apparatus, systems, and computer program products that can include, perform, and/or implement the methods are also disclosed herein.
