Hard Disk Drives

All disk drives installed on the appliance.

For each drive, the following information is displayed:

• The disk type
  Click on this link to view additional information about the drive. For further information, see Viewing Detailed Information About a Disk Drive.
• The disk size in GB
• The array to which the disk is assigned
• The disk status. For a list of possible statuses, see Hard Drive Statuses.

Note that you may notice a discrepancy between the disk capacity stated on the disk's packaging and the disk capacity displayed in the appliance Dashboard. This difference is due to the fact that vendors define 1 GB as 1 billion (10⁹) bytes, while computers define 1 GB as 2³⁰ bytes.
