Abstract: A method of operating a telemetry capture system within a data storage system comprising storage devices is provided. The method includes generating a telemetry packet, and providing the telemetry packet to one or more taps via a telemetry path independent of data and control paths within the storage devices. The method also includes capturing the telemetry packet in one or more of the taps, and generating real-time telemetry data based at least on the telemetry packet.

Abstract: A method of operating a storage controller is provided. The method includes receiving data transferred by a host for storage in a target partition of a storage media, and detecting properties of the data. The method also includes establishing one or more inferred partitions on the storage media based at least on the properties of the data, and based at least on the properties of the data, sorting subsets of the data for storage within the target partition and the one or more inferred partitions.

Abstract: A method of operating a storage controller is provided. The method includes determining encoded data to be written to a storage media by applying at least an initial encoding comprising a first error correcting code type and a subsequent encoding comprising a second error correcting code type. The method further includes writing the encoded data to the storage media, and responsive to reading the encoded data from the storage media, processing the encoded data into primary decoded data using one or more primary decoders employing the second error correcting code type and detecting when data errors arise in the decoded data. The method also includes based at least on detecting one or more data errors in the decoded data, processing the encoded data into secondary decoded data using one or more secondary decoders employing the first error correcting code type.

Abstract: A storage system is provided. The storage system includes a workload manager with visibility to host data operations for a storage drive. The workload manager is configured to determine an operation schedule comprising the host data operations and data migration operations for storage media of the storage drive, and instruct a storage media manager to perform the data migration operations and the host data operations in accordance with the operation schedule. The storage system also includes a storage media manager configured to receive instructions from the workload manager in accordance with the operation schedule, and responsively perform the data migration operations and the host data operations.

Abstract: A storage controller is provided. The storage controller includes a host interface, a media interface, and a processing system coupled with the host interface and the media interface. The processing system is configured to configured to maintain a translation table that relates logical addressing to physical blocks of the one or more storage media using at least an extents-based scheme in the translation table to relate the logical addressing to the physical blocks, wherein the extents-based scheme comprises a starting location combined with span length of a sequential portion of data stored on the one or more storage media, and the processing system also configured to handle storage operations of the storage drive in accordance with the translation table.

Abstract: Storage devices, storage controllers, and apparatuses are provided for providing one-time writeable storage devices. In an implementation, a storage device may include a data storage medium including data storage locations and a controller. The controller is coupled to the data storage medium and is configured to receive at least write operations for storage of data onto the data storage medium. The controller is further configured to provide a write-once mode of operation that prevents the data written to ones of the data storage locations of the data storage medium from being overwritten or erased by further data directed for storage to the ones of the data storage locations.
