Abstract: A method of operating a storage controller is provided. The method includes receiving a request from a partition creator, for a first partition within a storage system, the first partition comprising one or more sequentially numbered data blocks, and receiving first partition parameters from the partition creator, the first partition parameters comprising a size of the one or more sequentially numbered data blocks. The method also includes creating the first partition within the storage system, through a storage interface, based on the first partition parameters, receiving first host data from a host, configuring the first host data as first storage data for storage within the first partition within the storage system, and sequentially storing the first storage data in the one or more sequentially numbered data blocks in the first partition, through the storage interface.

Abstract: A storage controller is provided. The storage controller includes a host interface, a drive interface, and a quality of service control module coupled with the host interface and the drive interface. The QoS module includes read and write queues for each data stream, each queue associated with corresponding token buckets, and an arbiter, configured to receive requests from the read and write queues, and to service the read and write queues in an order at least partially determined by a quantity of tokens in each token bucket. The QoS module also includes a quality of service measurement module, configured to measure quality of service levels for each of the read and write queues, and a bandwidth allocation manager, configured to allocate tokens to each token bucket at a rate corresponding to the service level agreements and the measured quality of service level for each of the read and write queues.

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 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 for a storage system is provided. The storage system includes a host interface, a storage interface, a buffer coupled with the host interface and the storage interface, a storage encoder coupled with the buffer, and a storage decoder coupled with the buffer. The storage encoder and storage decoder are configured to use scatter-gather lists in reading data streams from the buffer, and storing data streams to the buffer. They are also configured to provide error correction coding and decoding, with the ability to generate data blocks for missing data blocks.

Abstract: A method of operating a data storage system is provided. The method includes establishing a user region on a non-volatile storage media of the data storage system configured to store user data, and establishing a recovery region on the non-volatile storage media of the data storage system configured to store recovery information pertaining to at least the user region. The method also includes updating the recovery information in the recovery region responsive to at least changes to the user region, and responsive to at least a power interruption of the data storage system, rebuilding at least a portion of the user region using the recovery information retrieved from the recovery region.
