Planning and Installation
System placement options
The Symmetrix DMX-3 system configurations can be installed in
several different flooring environments. The system can be installed
on a nonraised floor or raised floor environment. Although it is not
required, the raised floor environment is the preferred installation
environment.
“Floor load-bearing requirements” on page 295 lists
the floor loading requirements for the Symmetrix DMX-3 installation.
When planning the DMX-3 system placement, EMC recommends
positioning the storage bay frame first so that the closed front door
aligns with the floor tile edge. The system bay frame is then aligned
with the storage bay frames and are bolted together later. When the
system bay and all the storage bay doors are closed, the system bay is
slightly recessed in relation to the storage bays because the depth of
the system bay door is less than the depth of the storage bay doors.
Figure 71 on page 293 shows the placement of a DMX-3 with a system
bay and four storage bays on a level nonraised floor.
Note: In a nonraised floor environment, ensure that the room meets
environmental specification requirements. Refer to “Environmental data” on
page 266 .
