This is the status of the shelf. A warning message is displayed if a disk has
failed and RAID is being rebuilt. You will need to check the Shelves page to
find the exact location of the disk that has failed.
This is the configuration status of the shelf. It is shown as not configured if it
is not yet part of the storage pool.
This shows the number of disks per shelf. The first number refers to the number
of disks in the RAID; the second number is the online spare, It is normally
11+1 but can change to show the number of active disks in use.
The bar indicates how much of the disk has been used to store backup data
from the host(s). The maximum storage capacity is shown to the right of the
bar. The system will send warning messages to email recipients (if configured)
when the storage is reaching capacity. The Storage icon on the Summary
page will also indicate that space is running out.
This is the actual amount of storage space that is used and allocated. 3 GB
is automatically allocated for each cartridge when a library is created and
this is included in this figure.
The deduplication ratio is updated whenever data is written to storage.
