Disk-array enclosures
EMC VNX8000 Hardware Information Guide 85
Each power supply is an auto-ranging, power-factor-corrected, multi-output, offline
converter with its own line cord. Each supply supports a fully configured DAE and shares
load currents with the other supply. The drives and LCCs have individual soft-start
switches that protect the disk drives and LCCs if they are installed while the disk
enclosure is powered up. The enclosure cooling system includes two dual-blower
modules.
3U, 15 (3.5-inch) DAE (DAE6S)
The 3U, 15 DAE (2.5- or 3.5-inch) disk drive DAE in the VNX8000 platform is 3U (5.25
inches) high and includes 15 disk drives. It uses a 6-Gb/s SAS interface for
communication between the storage processor enclosure (SPE) storage processors (SPs)
and the DAE.

On the front, the VNX8000 platform 3U, 15 (2.5- or 3.5-inch) disk drive DAE carrier
includes the following hardware components:
◆ 2.5-inch 6-Gb/s SAS, 6-Gb/s NL-SAS, or Flash disk drives (hot-swappable)
◆ 3.5-inch 6-Gb/s SAS, 6-Gb/s NL-SAS, or Flash disk drives (hot-swappable)
◆ Status LEDs
Figure 67 shows the location of these components.
Note: In a VNX8000 platform, when using the 3U, 15 (2.5- or 3.5-inch) disk drive carrier,
the maximum amount of disk drives is 1,500.
