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.</p> <p>Users do not rely on storage servers to provide <i>confidentiality</i> nor <i>integrity</i> 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.</p> <p>Users rely on storage servers for <i>availability</i>. The ciphertext is erasure-coded and distributed across <cite>N</cite> storage servers (the default value for <cite>N</cite> is 10) so that it can be recovered from any <cite>K</cite> of these servers (the default value of <cite>K</cite> is 3). Therefore only the simultaneous failure of <cite>N-K+1</cite> (with the defaults, 8) servers can make the data unavailable.</p> -- 2.45.2
