The OSS Name Server is responsible for translating OSS path names into Guardian $volume.subvol.file type names and vice versa. The Name Server also provides the isolation of physical disk drives from the unified path names. Path names do not generally represent physical volumes except when representing Guardian format file names.
A system running OSS has at least one Name Server running, but usually one Name Server per CPU.
