Overview
lists the Cache Protection Module LEDs.
Disk-array enclosure
Lifting the DAE and installing it to or removing it from a rack is a two to three-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 VNXe3150 platform supports two types of disk-array enclosures (DAEs) across a
6-Gb/s SAS bus. The DAEs used in the VNXe3150 platform are the:
◆
2U, 12 (3.5-inch) disk drive DAE
◆
2U, 25 (2.5-inch) disk drive DAE
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 VNXe3150 platform supports up to seven 2U, 12 (3.5-inch)
disk drive DAEs or a maximum of 96 (3.5-inch) disk drives.

In a dual SP, when the 2U, 25 (2.5-inch) disk drive DAE is used with a 2U, 25 (2.5-inch)
disk drive DPE, the VNXe3150 platform supports up to three 2U, 25 (2.5-inch) disk drive
DAEs or a maximum of 100 (3.5-inch) disk drives.

IMPORTANT
When calculating the number of drives for your VNXe3150 platform, the DPE in a dual SP
configuration is included in the total drive slot quantity of from 96 to 100 drives. If the
total drive slot quantity exceeds from 96 to 100, you will not be able to add another DAE.
In a single SP configuration, the total drive slot quantity of from 48 to 50 drives is
possible. If the total drive slot quantity exceeds from 48 to 50, you will not be able to add
another DAE.

4. In a single SP configuration, the VNXe3150 platform can support up to three 2U, 12 (3.5-inch) disk
drive DAEs or a maximum of 48 disk drives.
5. In a single SP configuration, the VNXe3150 platform can support up to one 2U, 25 (2.5-inch) disk
drive DAEs or a maximum of 50 disk drives.
