Disk-array enclosures
4U, 60 (2.5- or 3.5-inch) DAE (DAE7S)
IMPORTANT
in a VNX8000 platform, the 4U, 60 (2.5- or 3.5-inch) DAE is presently supported in a Dense
rack configuration. This Dense rack is 40U high and 44 inches (111.76 cm) deep. Each 4U
DAE that goes in the Dense rack weighs 57.8 lb (26.28 kg) empty and 213 lb (96.62 kg)
fully loaded. As a result; whenever the 4U DAE configuration is ordered, it is assembled
and configured at the factory before shipping.
Access to the internal components in a 4U, 60 (DAE7S) enclosure mounted 31U (4.5 ft or
1.38 m) or higher above the floor requires an appropriate EMC service ladder and is
restricted to authorized service personnel only. Attempts to service disks, fans, or other
DAE components mounted 31U or higher without a recommended EMC service ladder and
personnel may result in serious personal injury. If an EMC service ladder is on site, this
ladder is the property of EMC and is only available for use by authorized EMC service
personnel.
If installing a new 4U, 60 DAE or replacing an existing 4U, 60 DAE above 31U is necessary,
then an appropriate portable mechanical lifting device is required. For more information
about this type of device, see "Appendix B: Field lift tool and accessory kit" on page 168.
The 4U, 60 (2.5- or 3.5-inch) disk drive DAE in the VNX8000 platform is 4U (7 inches) high
and includes 60 disk drives. Figure 93 shows an example of the front and rear views of a
4U, 60 (2.5- or 3.5-inch) DAE.
