Abstract: A plurality of storage nodes in a single chassis is provided. The plurality of storage nodes in the single chassis is configured to communicate together as a storage cluster. Each of the plurality of storage nodes includes nonvolatile solid-state memory for user data storage. The plurality of storage nodes is configured to distribute user data and metadata associated with the user data throughout the plurality of storage nodes such that the plurality of storage nodes maintain the ability to read the user data, using erasure coding, despite a loss of two of the plurality of storage nodes. The plurality of storage nodes configured to initiate an action based on the redundant copies of the metadata, responsive to achieving a level of redundancy for the redundant copies of the metadata. A method for accessing user data in a plurality of storage nodes having nonvolatile solid-state memory is also provided.

Abstract: A method for proactively rebuilding user data in a plurality of storage nodes of a storage cluster 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 storage nodes. The method includes determining that one of the storage nodes is unreachable and determining to rebuild the user data for the one of the storage nodes that is unreachable. The method includes reading the user data across a remainder of the plurality of storage nodes, using the erasure coding and writing the user data across the remainder of the plurality of storage nodes, using the erasure coding. A plurality of storage nodes within a single chassis that can proactively rebuild the user data stored within the storage nodes is also provided.

Abstract: A method of operating a remote procedure call cache in a storage cluster is provided. The method includes receiving a remote procedure call at a first storage node having solid-state memory and writing information, relating to the remote procedure call, to a remote procedure call cache of the first storage node. The method includes mirroring the remote procedure call cache of the first storage node in a mirrored remote procedure call cache of a second storage node. The storage cluster includes the first storage node and the second storage node. The storage system includes the first storage blade and the second storage blade. A storage node and storage cluster are also provided.

Abstract: A storage cluster is provided. The storage cluster includes a plurality of storage nodes within a single chassis. Each of the plurality of storage nodes has nonvolatile solid-state memory for storage of user data. The plurality of storage nodes are configured to distribute the user data and metadata throughout the plurality of storage nodes with erasure coding of the user data such that the plurality of storage nodes can access the user data, via the erasure coding, with a failure of two of the plurality of storage nodes. The plurality of storage nodes are configured to employ the erasure coding to reconfigure redundancy of the user data responsive to one of adding or removing a storage node.
