Configure Storage Disks
The Storage Disk option enables you to view, add, edit or delete storage disks.
Storage disks are external devices on UNIX-based file systems that can be used for long term data storage. Storage disks function and operate the same way as physical tape media. You can add up to 16 storage disks.
When a storage disk is configured, the StorNext Storage Manager moves data to storage disks for long-term retention in addition to, or instead of tape. This enables users to leverage the specialized third-party functionality of appliances or store small files that might take longer to retrieve from tape. Many users will still use tape for long term storage and vaulting, but storage disk can be used to create tape-free archives.
Here are a few differences storage disks have over tape media:
-
A storage disk either belongs to no policy class, or belongs to a single policy class
-
A storage disk can store file copies only with the same copy ID.
Note: Before you create a storage disk, the disks you plan to use must reside in an existing, mounted file system.
Use Case | Recommendation |
---|---|
File System configuration includes storage disks. |
Avoid using that file system for any data other than storage disk stored data. Note: If your file system includes storage disks and you accidentally fill it with unrelated user data (for instance, non-storage disk data) call the Quantum Technical Assistance Center and request the procedure to clean up and transcribe data. |
Configuration includes Shared File Systems |
Use complete and physically dedicated file systems (snfs, local, NFS, or other,) for storage disk data. Note: Avoid shared file systems or file systems with linked directories. |
Caution: Storage disks can be an important and integral part of your system, but you should NEVER rely solely on storage disks as your only backup location.
