v Use noncombustible protective molding to eliminate sharp edges on all floor
cutouts to prevent damage to cables and hoses, and to prevent casters from
rolling into the floor cutout.
v Seal raised-floor cable openings to prevent the escape of chilled air.
v Pedestals must be firmly attached to the structural (concrete) floor by using an
adhesive.
For more information, see “Preparing for raised-floor installation and cabling” on
page 24.
Non-raised floor considerations
Raised floors are preferred because they provide better support for the cabling and
to ensure efficient cooling for the FlashSystem A9000R system; however, overhead
cabling at the rear of the rack is available when the FlashSystem A9000R system is
installed on a non-raised floor.
Unlike raised-floor cabling, the installation planning, cable length, and the rack
location, in relation to the cable opening at the top of the rack, are critical to the
successful installation when using overhead cabling.
For more information, see “Preparing for non-raised-floor installation and cabling”
on page 25.
Floor-load requirements
You must ensure that the floor load rating can support the weight of the
FlashSystem A9000R system.
Floor reinforcement must support the weight of the FlashSystem A9000R system
over a specific area, as shown in Table 5. These measurements are slightly less than
the footprint area of the system, due to the overhang of the door.
To support future scale-out capability (MES) upgrades, the installation site must
provide floor weight-support requirements to support a full rack configuration.
