Scope:

The Filesystems part of the Storage Management Technical Specification 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 that deal with filesystems and management interface functions that may be used by other autonomous profiles not included in this part of the specification.

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 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 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 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 defined in this version of

the specification include:

• The File Export (component) Profile

This component profile defines the elements used to model the exporting of filesystems or directories for any autonomous profile that exports file data to remote systems.

• The File Export Manipulation (component) Profile

This component profile defines the elements used to model the services for creating, modifying and deleting the file shares (the representation of exported filesystems or directories) for any autonomous profile that provides manipulation of exported filesystems or directories.

• The File Storage (component) Profile

This component profile defines the elements used to model the storage of filesystems on logical disks. This profile does not have services for maintaining the mapping of filesystems to logical disks. These services are addressed in the Filesystem Manipulation Profile.

• The Filesystem (component) Profile

This component profile defines the elements used to model filesystems and its related elements, such as logical files, directories and information on how the filesystem is addressed when mounted to a specific system. The services for defining and maintaining the information in the Filesystem Profile are contained in the Filesystem Manipulation Profile.

• The Filesystem Manipulation (component) Profile

This component profile defines the elements used to model the services for creating, modifying and deleting filesystems and their related elements.

 

 

• The Filesystem Quotas (component) Profile

This component profile defines the elements used to model the elements associated with creating, maintaining and reporting on quotas on various filesystem elements.

Project need:

To align Canadian requirements with those of the respective international standards being proposed for adoption and to maintain alignment between Canadian information and communication technology standards and each respective international standard. This proposed New Standard is being developed at the request of P123 – Technical Committee on Information Technology. It will provide the industry with the latest standards available in the ICT field.

The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.
