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.
