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. A fully loaded 2U DAE, 3U DAE, or 4U DAE
weighs approximately 45 lb (20.41 kg), 68 lb (30.84 kg), or 213 lb (96.62 kg),
respectively.
The Block and File (Unified) VNX5700 platform supports the expansion of three types of
disk-array enclosures (DAEs) across a 6-Gb/s SAS bus:
◆ 3U, 15 (3.5-inch) DAE
◆ 2U, 25 (2.5-inch) DAE
◆ 4U, 60 (2.5- or 3.5-inch) DAE
20
Note: “4U, 60 (2.5- or 3.5-inch) DAE” on page 79 provides a complete description of
the 4U, 60 disk drive DAE.
The Block and File (Unified) VNX5700 platform supports up to thirty-three 3U, 15
(3.5-inch) DAEs (for a total of 495 3.5-inch disk drives), up to twenty 2U, 25 (2.5-inch)
DAEs (500 2.5-inch disk drives), or up to seven 4U, 60 (2.5- or 3.5-inch) DAEs
21
(for a total
of 420 disk drives)
22
.
IMPORTANT
As described in the previous paragraph, you cannot build an environment beyond the
supported software and hardware requirements for that VNX5700 platform.
Do not try to
add more disk drives than the software can support.
Each Block and File (Unified) VNX5700 platform DAE typically consists of the following
components:
◆ Drive carrier
◆ Disk drive
◆ Midplane
◆ Link control cards (LCCs)
◆ Inter Connect Modules (ICMs)
23
◆ Power supply/cooling modules
24
◆ EMI shielding
20. The 4U, 60 disk drive DAE with the VNX5700 platform environment is factory only delivery.
21. This configuration is true when 4U, 60 disk drive DAE is used as the vault drive. If the 3U 15 disk
drive DAE is used as the vault drive, the total disk drive count is 450 disk drives.
22. This configuration is true for a Block and File VNX5700 platform. In the Block version, up to eight
4U DAEs and one 3U DAE (a maximum of 495 disk drives) is possible.
23. The 4U, 60 disk drive DAE includes Inter Connect Modules (ICMs).
“4U, 60 (2.5- or 3.5-inch) DAE” on
page 79
provides more information about the 4U, 60 disk drive DAE.
24. The 4U, 60 disk drive DAE has separate power supplies and cooling modules (fans).
