Chapter 5 –Volume Permissions and Workflows
Users Permissions to Volumes
Up to 200 users may be given permissions to over 250 volumes per server. User
permissions are based on the OS login user that was created or the user created
after the User and Password feature has been enabled. If multiple users require
different permissions, but use the same workstation, the User and Password feature
is recommended. Enabling the “Unmount Volumes on Exit” feature from the User
Mode menu should be used for this type of workflow. Multiple user accounts can be
created on the local machine, or users may login to the local machine through Active
Directory. If logging in with Active Directory, the LDAP user feature can be used to
sync and create new TerraBlock users.
The login name sent to the TerraBlock server after login at a client workstation will
be the basis for permissions when displaying and mounting new volumes. If the
Administrator wishes the permissions to remain the same on a per client basis, the
same user should be used when logging in with the TerraBlock Manager.
Permissions to volumes can be granted to allow Write, Read Only or no access.
Multiple users may have write
permissions
to a single volume. Keep in mind, while in
Single-user Write mode, only the first user to mount the volume with write access
will have the ability to write to the volume. All other users will be limited to mount
with Read Only access. Multi-user Write gives all users the ability to mount the
same volume with write access simultaneously.
Volume Workflows for Single User Write
Virtual volumes benefit from the ability to be managed on a per-project basis. The
media management that project-based workflow allows will simplify the clean-up,
consolidation, archive and eventual deletion of project data.
A volume created for a particular project can be resized as the project grows. After
the project is completed or archived, the volume can be deleted to make room for
additional projects entering the facility. This flexibility offers the administrator the
opportunity to be very particular about the location of media and create unique
permissions to small writable volumes, or use the high-capacity volume option to
create very few multi-terabyte volumes and simplify the user workflow with an open
access approach.
There is never a need to partition all the space immediately. The administrator may
choose to create volumes only as needed for a particular week or month. Even if
some static space is needed for users that create content for all projects, or require
dedicated capacity for media ingest or archive operations, some of the TerraBlock
storage can always be left unallocated for future needs.
Volume Workflows for Multi-user Write
The Facilis Shared File System (SFS) allows users to create volumes that are larger
and have Multi-user Write access for multiple clients to write data. However, the
media management of very large volumes can become cumbersome unless an asset
management system is put in place for search ability.
