Abstract
A plurality of storage nodes in a single chassis is provided. Each of the plurality of storage nodes has a storage capacity with nonvolatile solid-state memory for user data storage. The plurality of storage nodes is configured to support uniform storage capacities and non-uniform storage capacities among the plurality of storage nodes, as a storage cluster. The plurality of storage nodes is configured to distribute the 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.
