Annotation

This part of ISO/IEC 24775 defines management profiles for Autonomous (top level) profiles for programs and devices whose central function is providing support and access to file data. In addition, it provides documentation of component profiles (or subprofiles) that deal with filesystems and management interface functions that may be used by other autonomous profiles not included in this part of the standard.

There is an informative annex that describes how storage is mapped from block storage to file shares exported by the filesystem and the mechanisms involved in establishing those mappings. This annex is recommended for getting an overview of how the filesystem models work.

This part of ISO/IEC 24775 includes two 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 standard defines a number of component profiles, which are used by the autonomous NAS profiles and might also be used by other autonomous profiles that feature filesystem elements and services. The component profiles (subprofiles) defined in this version of the standard include:
