    Abstract: A method for hardware assisted data lookup in a storage unit is provided. The method includes formatting data in at least one of a plurality of data formats for storage in the storage unit. The method includes configuring a logic unit with one or more parameters associated with the plurality of data formats and identifying incoming data with the one or more parameters as an instruction for execution.

    Abstract: A method for administration through files in a storage cluster is provided. The method includes distributing user data, including files, throughout a plurality of storage nodes having non-volatile solid-state memory, through erasure coding. The plurality of storage nodes are housed within a single chassis that couples the storage nodes as the storage cluster. The method includes receiving at the storage cluster a command to write a file or read a file, the file having a filename. The method includes determining whether the filename is reserved and determining an administrative action according to the file, responsive to determining that the filename is reserved. The method includes initiating the administrative action. A storage system is also provided.

    Abstract: A method of applying a data format in a direct memory access transfer is provided. The method includes distributing user data throughout a plurality of storage nodes through erasure coding, wherein the plurality of storage nodes are housed within a single chassis that couples the storage nodes as a cluster, each of the plurality of storage nodes having nonvolatile solid-state memory for user data storage. The method includes reading a self-describing data portion from a first memory of the nonvolatile solid-state memory and extracting a destination from the self-describing data portion. The method includes writing data, from the self-describing data portion, to a second memory of the nonvolatile solid-state memory according to the destination.

    IPC: G06F3/06

    Abstract: A method of processing transactions associated with a command in a storage system is provided. The method includes receiving, at a first authority of the storage system, a command relating to user data. The method includes sending a transaction of the command, from the first authority to a second authority of the storage system, wherein a token accompanies the transaction and writing data in accordance with the transaction as permitted by the token into a partition that is allocated to the second authority in a storage device of the storage system.

    IPC: G06F3/06

    Abstract: A system and method for effectively scheduling read and write operations among a plurality of solid-state storage devices. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array comprises an I/O scheduler. The characteristics of corresponding storage devices are used to schedule I/O requests to the storage devices in order to maintain relatively consistent response times at predicted times. In order to reduce a likelihood of unscheduled behaviors of the storage devices, the storage controller is configured to schedule proactive operations on the storage devices that will reduce a number of occurrences of unscheduled behaviors.
