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

Abstract: A system and method for offset protection data in a RAID array. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array is configured to store user data in a first page of a first storage device of the plurality of storage devices; generate intra-device protection data corresponding to the user data, and store the intra-device protection data at a first offset within the first page. The controller is further configured to generate inter-device protection data corresponding to the first page, and store the inter-device protection data at a second offset within a second page in a second storage device of the plurality of storage devices, wherein the first offset is different from the second offset.
