Abstract: A storage device for adaptive wear leveling within a data storage system is provided. The storage device includes a host interface configured to receive storage operations for storage and retrieval of data on storage media, a media interface configured to read and write data to the storage media, and a storage controller configured to provide wear leveling for the storage media using a plurality of partitions within the storage media.

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 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 controller for a storage system includes a host interface, configured to receive data for storage within the storage system, and to transmit data from the storage system to a host system, and one or more storage interfaces, configured to transmit data to storage media, and to receive data from the storage media. The storage controller also includes a plurality of data paths configured to process and transfer data between the host interface and the one or more storage interfaces, the plurality of data paths comprising a first quantity of read data paths configured to interpret data retrieved from the storage media, and a second quantity of write data paths configured to prepare data for storage onto the storage media, and an arbiter configured to dynamically arbitrate access to the one or more storage interfaces by the read data paths and the write data paths.

Abstract: A storage controller is provided. The storage controller includes a host interface, a media interface, and a processing system. The processing system is configured to receive data from the host system, select write locations within the storage media for writing the data, and to select a write format based at least in part on the write locations within the storage media. The processing system is further configured to select write parameters based at least in part on the write locations within the storage media and media states of the write locations within the storage media, and to write the data to the write locations within the storage media using the selected write format and write parameters.

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.
