A "storage grid" is made up of a number of storage servers. A storage server has local attached storage (typically one or more hard disks). A "gateway" uses the storage servers and provides a filesystem over a standard protocol such as HTTP(S), FUSE, SMB, or (S)FTP.

Users do not rely on storage servers to provide confidentiality nor integrity for their data -- instead all of the data is encrypted and integrity-checked by the gateway, so that the servers can neither read nor alter the contents of the files.

Users rely on storage servers for availability. The ciphertext is erasure-coded and distributed across N storage servers (the default value for N is 10) so that it can be recovered from any K of these servers (the default value of K is 3). Therefore only the simultaneous failure of N-K+1 (with the defaults, 8) servers can make the data unavailable.
