Storage cluster
First Claim
1. A plurality of storage nodes in a single chassis, comprising:
- the plurality of storage nodes configured to communicate together as a storage cluster;
each of the plurality of storage nodes having nonvolatile solid-state memory for user data storage; and
the plurality of storage nodes configured to distribute the user data and metadata associated with the user data throughout the plurality of storage nodes such that the plurality of storage nodes maintain ability to read the user data, using erasure coding, despite a loss of two of the plurality of storage nodes.

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 the 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 chassis includes power distribution, a high speed communication bus and the ability to install one or more storage nodes which may use the power distribution and communication bus. A method for accessing user data in a plurality of storage nodes having nonvolatile solid-state memory is also provided.
