Managing 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.

Before you create a storage disk, the disks you plan to use 

must reside in an existing, mounted file system.
