Drives
A drive is an electromagnetic mechanical device that provides the physical storage media for data.
Overview and requirements
Before you replace a drive, you need to be aware of certain requirements and considerations.
Drives overview
You can replace a drive in either a 24-drive or 60-drive controller shelf or drive shelf.
24-drive shelves
The figures show how the drives are numbered in each type of shelf (the shelf's front bezel or end
caps have been removed).

including the DE5600 24-drive tray or the DE6600 60-drive tray. For instructions for replacing a
