Disk-array enclosure
Lifting the DAE and installing it to or removing it from a rack is a two-person job. If
needed, use an appropriate lifting device (mechanical lift). A fully loaded 2U, 12
(3.5-inch) DAE or 2U, 25 (2.5-inch) DAE weighs approximately 52 lb (23.6 kg) or 45 lb
(20.5 kg), respectively.
The VNXe3100 platform supports two types of disk-array enclosures (DAEs) across a
6-Gb/s SAS bus. The DAEs used in the VNXe3100 platform are the:
◆ 2U, 12 (3.5-inch) disk drive DAE
◆ 2U, 25 (2.5-inch) disk drive DAE
Note: The 2U 25, (2.5-inch) disk drive DAE is only supported when you have software
VNXe Operating Environment (OE) version 2.3.x and above installed.
In a dual SP system, when the 2U, 12 (3.5-inch) disk drive DAE is used with a 2U, 12
(3.5-inch) disk drive DPE, the VNXe3100 platform supports up to seven 2U, 12 (3.5-inch)
disk drive DAEs or a maximum of 96 (3.5-inch) disk drives.

disk drive DAEs and one 2U, 12 (3.5-inch) disk drive DAE or a maximum of 99 disk drives.
