Chapter 4 Storage Configuration and Expansion 49
A volume can be expanded up to 16 TBs, either as a standalone volume or as a
volume group.
Security Models, SnapTrees, and Volumes
Volumes are created with the Windows security model (which can be changed in
the
Securities > SnapTrees
page or when creating a share to point to the volume
root). Directories created in the root of a volume (aka SnapTree directories) in the
Web UI are automatically assigned either a Windows- or a UNIX-style security
model, based on the security model of the parent volume (this can also be
subsequently changed in the SnapTrees page or when creating a share pointing to
them). The security model determines the file-level security scheme that will apply
to files and folders within the volume or SnapTree directory.
Volume Management Tools
The Snap Server offers several tools for monitoring and controlling how storage
space on a volume is used.
You can view volume status from the
Storage > Volumes
screen.
Quotas
Quotas are configured in the
Storage > Quotas
screen of the Administration Tool.
Assigning quotas ensures that no one user or group consumes a disproportionate
amount of volume capacity. Quotas also keep tabs on how much space each user (or
NIS group) is currently consuming on the volume, allowing for precise tracking of
usage patterns. You can set individual quotas for any local, Windows domain, or
NIS user known to the Snap Server. Group quotas are available only for NIS
groups.
Function Navigation Path
Ongoing Maintenance Navigate to the Storage > Volumes screen, from which you
can create, view, edit, and delete volumes.
Email Notification The server can notify you when a volume is full. This allows
you to increase volume size or take other actions to ensure
workflows are not disrupted (
Server > Email Notification ).
Volume Usage You can view the current utilization totals for each volume,
from the
Storage > Volumes screen.
Quotas Use quotas ( Storage > Quotas ) to limit the amount of
storage space on a volume that specific users or groups can
consume. See Quotas for more information.
