Components of DS400 storage subsystems

The following sections show the components of the DS400 storage subsystem.
The hot-swap features of the storage subsystem enable you to remove and replace
hard disk drives and power supplies without turning off the storage subsystem.
Therefore, you can maintain the availability of the system while a hot-swap device
is removed, installed, or replaced.

Hard disk drive
You can install up to 14 Ultra320 hot-swap hard disk drive customer
replaceable units (CRUs) in the storage subsystem. Each hard disk drive
CRU contains a hard disk drive and tray.
The storage subsystem comes without installed hard disk drives and
contains filler panels in the unused drive bays. Before installing new drives,
you must remove the filler panels and save them. Each of the 14 bays must
always contain either a filler panel or a hard disk drive to maintain proper
cooling and airflow.
Use the blue latch on the tray handle to release or lock the hard disk drive
in place.
