Glossary

General

General Project Properties

This section of the BUI controls overall settings for the project that are independent of any particular protocol and are not related to access control or snapshots. While the CLI groups all properties in a single list, this section describes the behavior of the properties in both contexts.

For information on how these properties map to the CLI, see the Projects CLI section.

Space Usage

Space within a storage pool is shared between all shares. Filesystems can grow or shrink dynamically as needed, though it is also possible to enforce space restrictions on a per-share basis. For more information on pooled storage, see the concepts page.

Quota

Sets a maximum limit on the total amount of space consumed by all filesystems and LUNs within the project. For more information, see the shares section. Unlike filesystems, project quotas cannot exclude snapshots, and can only be enforced across all shares and their snapshots.

Reservation

Guarantees a minimum amount of space for use across all filesystems and LUNs within the project. For more information, see the shares section. Unlike filesystems, project reservation cannot exclude snapshots, and can only be enforced across all shares and their snapshots.

Inherited Properties

These are standard properties that can either be inherited by shares within the project. The behavior of these properties is identical to that at the shares level, and further documentation can be found in the shares section.

Custom Properties

Custom properties can be added as needed to attach user-defined tags to projects and shares. For more information, see the schema section.

Filesystem Creation Defaults

These settings are used to fill in the default values when creating a filesystem. Changing them has no effect on existing filesystems. More information can be found in the appropriate shares section.

LUN Creation Defaults

These settings are used to fill in the default values when creating a LUN. Changing them has no effect on existing LUNs. More information can be found in the appropriate shares section.
