RAID 60 Axles
When you create a RAID 60, you must specify the number of axles. An axle
refers to a single RAID 6 logical drive that is striped with other RAID 6 logical
drives to make RAID 60. An axle can have from 4 to 16 physical drives,
depending on the number of physical drives in the logical drive.
The chart below shows RAID 60 logical drives with 8 to 20 physical drives, the
available number of axles, and the resulting distribution of physical drives on
each axle.
