Abstract: A method is disclosed that includes, generating, by a controller of a storage device, telemetry data associated with the storage device and stored in a memory device of the storage device. The method further includes determining, by the controller, a telemetry data loss warning condition indicating that a portion of the telemetry data is predicted to be overwritten in the memory device by more recent telemetry data. In response to determining the telemetry data loss warning condition, the controller transmits, to a host device, an asynchronous event notification indicating the telemetry data loss warning condition.

Abstract: Methods of protecting cache data are provided. For example, various methods are described that assist in handling dirty write data cached in memory by duplication into other locations to protect against data loss. One method includes caching a data item from a data source in a first cache device. The data item cached in the first cache device is designated with a first designation. In response to the data item being modified by a data consumer, the designation of the data item in the first cache device is re-assigned from the first designation to a second designation, and the data item with the second designation is copied to a second cache device.
