    摘要: A method for proactively rebuilding user data in a plurality of storage nodes of a storage cluster in a single chassis is provided. The method includes distributing user data and metadata throughout the plurality of storage nodes such that the plurality of storage nodes can read the user data, using erasure coding, despite loss of two of the plurality of storage nodes. The method includes determining to rebuild the user data for one of the plurality of storage nodes in the absences of an error condition. The method includes rebuilding the user data for the one of the plurality of storage nodes. A plurality of storage nodes within a single chassis that can proactively rebuild the user data stored within the storage nodes is also provided.

    摘要: A storage system that supports independent scaling of compute resources and storage resources, the storage system including: one or more chassis, wherein each chassis includes a plurality of slots, each slot configured to receive a blade; a plurality of compute resources; a plurality of storage resources; a plurality of blades, where each blade includes at least one compute resource or at least one storage resource and each of the storage resources may be directly accessed by each of the compute resources without utilizing an intermediate compute resource; a first power domain configured to deliver power to one or more of the compute resources; and a second power domain configured to deliver power to the storage resources, wherein the first power domain and the second power domain can be independently operated.

    摘要: 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.

    摘要: A storage system includes a plurality of storage nodes. Each storage node of the plurality of storage nodes includes a plurality of non-volatile memory modules. The storage system also includes a processor operatively coupled to the plurality of storage nodes, to perform a method. The method includes receiving incoming data. The method further includes storing the incoming data in a redundant array of independent drives (RAID) stripe in the data storage system. The RAID stripe includes groups of data shards. Each group of data shards and a respective group parity shard are stored across the plurality of nodes of the data storage system. A set of stripe parity shards are stored in a first storage node of the plurality of storage nodes.
