    摘要： Methods and systems for reading from and writing to a distributed, asynchronous and fault-tolerant storage system. The storage system includes storage nodes communicating with clients. The method includes a first client writing an object to the storage system and a second client reading the object from the storage system. For the first client, previous transient metadata relating to a previously written version of the object is retrieved and a new version of the object together with new transient metadata is stored. For the second client, a set of transient metadata from a third set of nodes amongst storage nodes is retrieved, a specific version of the object as stored on the storage system is determined, and a specific version of the corresponding object from a fourth set of nodes amongst storage nodes is retrieved. Two sets of nodes amongst all sets have at least one node in common.

    摘要： A system, method apparatus, and computer readable medium for managing renewal of a dynamic set of data items. Each data item has an associated renewal deadline, in a data item management system. A renewal schedule allocates to each data item a renewal interval for renewal of the data item. On addition of a new data item, if a potential renewal interval having a duration required for renewal of the data item, and having an ending at the renewal deadline for that item does not overlap a time period in the schedule during which the system is busy, the renewal schedule is automatically updated by allocating the potential renewal interval to the new data item. If the potential renewal interval does overlap a busy period, the renewal schedule is automatically updated by selecting an earlier renewal interval for at least one data item in the set.

    摘要： A mechanism is provided for controlling a solid state storage device in which the solid state storage comprises erasable blocks each comprising a plurality of data write locations. Input data is stored in successive groups of data write locations, each group comprising write locations in a set of erasable blocks in each of a plurality of logical subdivisions of the solid state storage. The input data is error correction encoded such that each group contains an error correction code for the input data in that group. Metadata, indicating the location of input data in the solid state storage, is maintained in memory. An indication of validity of data stored in each data write location is also maintained. Prior to erasing a block, valid input data is recovered from the group containing write locations in that block. The recovered data is then re-stored as new input data.
