10Managing Storage Disks
StorNext provides the ability to configure storage disks that function and
operate the same way as physical tape media. Storage disks are external
devices on UNIX-based file systems that can be used for long term data
storage.
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, aside from
the obvious cost-saving benefit:
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
After you create a storage disk, observe the following usage
recommendations:
If your file system includes storage disks, avoid using that file system
for any data other than storage disk stored data.
Note: Before you create a storage disk, the disks you plan to use
must reside in an existing, mounted file system.
