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 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) VNX5500 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 (DAE6S)
◆ 2U, 25 (2.5-inch) DAE (DAE5S)
◆ 4U, 60 (2.5- or 3.5-inch) DAE (DAE7S)
Note: “4U, 60 (2.5- or 3.5-inch) DAE” on page 88 provides a complete description of
the 4U, 60 disk drive DAE.
The Block and File (Unified) VNX5500 platform supports up to fifteen 3U, 15 (3.5-inch)
DAEs (a maximum of 240 3.5-inch disk drives), up to nine 2U, 25 (2.5-inch) DAEs (a
maximum of 250 2.5-inch disk drives), or up to a combination of three 4U, 60 (2.5- or
3.5-inch) DAEs and three 3U, 15 (3.5-inch) DAEs (a maximum 240 disk drives).
IMPORTANT
When calculating the number of drives for your platform, the DPE is included in the total
drive slot quantity of up to 240 to 250 drives. If the total drive slot quantity exceeds 240 or
250, you will not be able to add another DAE. Refer to the “Overview” section on page 4
for more information about the Block and File (Unified) VNX5500 platform DPEs.
Each Block and File VNX5500 platform DAE consists of the following components:
◆ Drive carrier
◆ Disk drive
◆ Midplane
◆ Link control cards (LCCs)
◆ Inter Connect Modules (ICMs)
1
◆ Power supply/cooling modules
2
◆ EMI shielding
1. The 4U, 60 disk drive DAE includes Inter Connect Modules (ICMs). “4U, 60 (2.5- or 3.5-inch) DAE”
on page 88 provides more information about the 4U, 60 disk drive DAE.
2. The 4U, 60 disk drive DAE has separate power supplies and cooling modules (fans).
