Storage Template Variables

The information collected in the Storage template variables defines attributes of the disks available in the system.

The Disks are tracked both by number (0, 1, 2, …​) and by device name (sda, vda, nvme0n1, …​).

For example, if ${Storage/Disks/2/Name} is equal to sda, the the disk model can be retrieved via both the ${Storage/Disks/2/Model} and the ${Storage/Disks/sda/Model} variables.

The tracked disks include also optical disk drives and removable devices (e.g., USB sticks).
