Abstract: A method for administration through files in a storage cluster is provided. The method includes distributing user data, including files, throughout a plurality of storage nodes having non-volatile solid-state memory, through erasure coding. The plurality of storage nodes are housed within a single chassis that couples the storage nodes as the storage cluster. The method includes receiving at the storage cluster a command to write a file or read a file, the file having a filename. The method includes determining whether the filename is reserved and determining an administrative action according to the file, responsive to determining that the filename is reserved. The method includes initiating the administrative action. A storage system is also provided.

Abstract: A method for securing data in a storage grid is provided. The method includes generating a storage key from key shares of at least two storage clusters of a storage grid having at least three storage clusters and generating a grid key from the storage key and an external secret. The method includes encrypting data with the grid key to yield once encrypted data and encrypting the once encrypted data with the storage key to yield twice encrypted data. The method includes storing the twice encrypted data in a first storage cluster of the storage grid and storing the twice encrypted data in a second storage cluster of the storage grid, wherein at least one method operation is performed by a processor.
