An apparatus comprises at least one processing device configured to receive unmap requests for freeing up data previously written to one or more storage regions of at least one storage device of a distributed storage system, the unmap requests being received from two or more write cache instances of two or more storage nodes of the distributed storage system. The processing device is also configured to identify at least a subset of the unmap requests which are directed to a given storage region of the at least one storage device. The processing device is further configured to provide the subset of the unmap requests to at least one storage controller associated with the at least one storage device of the distributed storage system responsive to determining that at least one designated unmap condition has been met.

An autonomous compute storage device system includes an autonomous compute storage device signature/application provisioning system coupled to a storage device. The storage device retrieves an autonomous compute signature from the autonomous compute storage device signature/application provisioning system and, as part of a storage operation being performed in a storage subsystem in the storage device, stores data in a memory subsystem that is accessible to the storage device. If the storage device determines that the autonomous compute signature matches the data that was stored in the memory subsystem, it retrieves an autonomous compute application from the autonomous compute storage device signature/application provisioning system, and executes the autonomous compute application to perform compute operations that are associated with the data that was stored in the memory subsystem and generate at least one compute operation result.

An information handling system ransomware protection device has a ransomware protection engine that implements secure snapshot policies in a domain of a storage device by taking a secure snapshot of a data object, by creating a point in time image of a storage object and retaining the point in time image of the storage object until a retention timer has expired. The ransomware protection engine also implements snapshot virtualization in the domain of the storage device by mapping the secure snapshot, and may implement vault semantics and operational controls to data in the domain of the storage device as management functions of the secure snapshot. The ransomware protection device may be, or include, an application specific integrated circuit that includes the ransomware protection engine and is coupled to, or in, the storage device, or a memory controller of the storage device may include the ransomware protection engine.

An autonomous compute storage device system includes a computing device and a storage device that is coupled to the computing device.
