Novell Storage Services (NSS) is a file system used by the Novell NetWare operating system and recently ported to SUSE Linux. It has some unique features that make it especially useful for, but not limited to, setting up shared volumes on a file server in a Local Area Network.
NSS is a 64-bit journaling file system with a balanced tree algorithm for the directory structure. Its published specifications (as of NetWare 6.5) are:
- Maximum file size: 8TiB
- Maximum volume size: 8TiB
- Maximum files per volume: 8 trillion, up to 8TiB total volume size
- Maximum mounted volumes per server: unlimited if all are NSS
- Maximum open files per server: 1 million
- Maximum directory tree depth: limited only by client
- Maximum volumes per partition: unlimited
- Maximum extended attributes: no limit on number of attributes.
- Maximum data streams: no limit on number of data streams.
- Unicode characters supported by default
- Support for different name spaces: DOS, Microsoft Windows Long names (loaded by default), Unix, Apple Macintosh
- Support for restoring deleted files (salvage)
- Support for transparent compression
- Support for encrypted volumes
- Support for data shredding
