Novell Storage Services (NSS) is a file system used by the Novell NetWare operating system. Recently (2004) support of NSS was introduced to SUSE Linux via low-level network NCPFS protocol. 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 partition size: 2TiB
- Maximum device size (Physical or Logical): 2TiB
- Maximum pool size: 8TiB
- Maximum volume size: 8TiB
- Maximum files per volume: 8 trillion
- 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
