Abstract: In at least one embodiment, in response to introduction of a first storage node into a storage network including a plurality of storage nodes, the first storage node discovers at least one second storage node that is a peer storage node. The first storage node downloads one or more versions of one or more shared soft configurations from the second peer storage node. In response to selection of a first version of a first shared soft configuration for activation, the first storage node subscribes to the first shared soft configuration and activates the first version of the selected shared soft configuration on the first storage node. Thereafter, in response to an update of the first shared soft configuration to a second version on the first storage node, the first storage node propagates the second version of the first shared soft configuration to the second storage node.

Abstract: In a data storage system, a hierarchical data structure, such as a file system or a database, is utilized to organize a hierarchical arrangement of device containers corresponding to various device identifiers of the plurality of hardware components in the target hardware system, scripts corresponding to various packet types of communication packets in the target hardware system, and responses corresponding to various packet data in the communication packets in the target hardware system. In response to receipt by a hierarchical emulation engine of a communication packet during emulation of the target hardware system, the communication packet including a device identifier, packet type and packet data, a response to the communication packet is determined by traversing the hierarchical arrangement based on the device identifier, packet type and packet data of the communication packet. The determined response is then provided.

Abstract: A data retention methodology for use in electrically rewritable nonvolatile storage systems is disclosed. The methodology collects characteristic data of the storage system (e.g., time stamps, program/erase cycles, sensed temperature over time, and others) and uses at least a portion of that data to associate various data retention schemes with the collected characteristic data. At power-on, the methodology determines a duration of a time during which power was not supplied to the storage system. The methodology also uses the power-on time to trigger the selection of an appropriate data protection scheme (e.g., enhanced ECC and/or read/scrub frequency). Dynamic selection and adjustment of the applied protection scheme may be based on the predetermined and/or calculated association between various protection schemes and the collected characteristic data of the storage system.

Abstract: A data retention methodology for use in electrically rewritable nonvolatile storage systems is disclosed. The methodology collects characterization data of the storage system (e.g., time stamps, program/erase cycles, sensed temperature over time, and others) and uses at least a portion of that data to associate various data retention schemes with the collected characterization data. At power-on, the methodology determines a duration of a time during which power was not supplied to the storage system.
