Symmetrix DMX-3 power requirements
The DMX-3 requires three-phase AC power. Each DMX-3 system bay
and storage bay has two power zones providing (2N) redundancy. A
fully populated system supports eight power supply modules.
Note: “Symmetrix DMX-3 power subsystems” on page 86 , “Electrical
specifications and power requirements” on page 270 , and “Power and
cooling data” on page 269 provide more information on power
requirements.
The customer is responsible for supplying and installing the required
receptacles on two separate power distribution units (PDUs) for Zone
A and Zone B power for the Symmetrix DMX-3 system bay and each
storage bay in advance of delivery.
Figure 69 and Figure 70 on
page 289 show the required power cabling for the Symmetrix DMX-3
system bay and each storage bay.
