Adding an optional 80-drive DAE
302-003-781
REV 01
July 2017
This document describes how to add an optional 80-drive DAE in
Unity All Flash and Unity Hybrid systems.
You will install the 80-drive DAE from the front of the rack, after installing the snap-in
rails into the selected space in the rack.
The enclosure is heavy and should be installed into or removed from a rack by two
people. To avoid personal injury and/or damage to the equipment, do not attempt
to lift and install the enclosure into a rack without a mechanical lift and/or help
from another person.
You do not have to power off any components to add a 80-drive DAE. If an additional
12-Gb SAS back-end I/O module is required to complete the installation, persisting that
I/O module requires a coordinated reboot of the array.
When Data at Rest Encryption is enabled, only drives that meet at least one of these
requirements can be used: factory new drives, securely erased/sanitized drives, or
previously encrypted drives.
