The Filesystems part of the Storage Management Technical Specification defines management profiles for 3 Autonomous (top level) profiles for programs and devices whose central function is providing support and 4 access to file data. In addition, it provides documentation of component profiles that deal with filesystems 5 and management interface functions that may be used by other autonomous profiles not included in this 6 part of the specification.
There is an informative annex that describes how storage is mapped from block storage to file shares 8 exported by the filesystem and the mechanisms involved in that establishing those mappings. This annex is recommended for getting an overview of how the filesystem models work.
This version of the Filesystems part of the Storage Management Technical Specification includes two 11 autonomous profiles:
• The NAS Head Profile
This profile defines the model and functions of a NAS device that exports file shares to remote users and gets its storage from a SAN (array devices attached to the NAS Head device).
• The Self-Contained NAS Profile
This profile defines the model and functions of a NAS device that exports file shares to remote users, but gets its storage from disk drives that are internal to the NAS device (instead of externally attached arrays).
In addition to these autonomous profiles, this part of the specification defines a number of component 19 profiles, which are used by the autonomous NAS profiles and might also be used by other autonomous profiles that feature filesystem elements and services.
