Floor load-bearing capacity
Storage arrays can be installed on raised floors. Customers must be aware that the load-bearing
capacity of the data center floor is not readily available through a visual inspection of the floor. The
only definitive way to ensure that the floor is capable of supporting the load associated with the
array is to have a certified architect or the data center design consultant inspect the specifications
of the floor to ensure that the floor is capable of supporting the array weight.
CAUTION
l
Customers are ultimately responsible for ensuring that the floor of the data center on
which the array is to be configured is capable of supporting the array weight, whether the
array is configured directly on the data center floor or on a raised floor supported by the
data center floor.
l
Failure to comply with these floor loading requirements could result in severe damage to
the storage array, the raised floor, subfloor, site floor and the surrounding infrastructure
should the raised floor, subfloor or site floor fail.
l
Notwithstanding anything to the contrary in any agreement between Dell EMC and the
customer, Dell EMC fully disclaims any and all liability for any damage or injury resulting
from the customer’s failure to ensure that the raised floor, subfloor and/or site floor are
capable of supporting the storage array weight. The customer assumes all risk and liability
associated with such failure.
Raised floor requirements
Best practice is to use 24 x 24 inch heavy-duty, concrete-filled steel floor tiles. If a different size
or type of tile is used, the customer must ensure that the tiles have a minimum load rating that is
sufficient for supporting the storage array weight. Ensure proper physical support of the system
by following requirements that are based on the use of 24 x 24 in. (61 x 61 cm) heavy-duty,
concrete-filled steel floor tiles.
Raised floors must meet the following requirements:
l
Floor must be level.
l
Floor tiles and stringers must be rated to withstand concentrated loads of two casters each
that weigh up to 700 lb (317.5 kg).
Note: Caster weights are measured on a level floor. The front of the array weighs more than
the rear of the configuration.
l
Floor tiles and stringers must be rated for a minimum static ultimate load of 3,000 lb (1,360.8
kg).
l
Floor tiles must be rated for a minimum of 1,000 lb (453.6 kg) on rolling load.
l
For floor tiles that do not meet the minimum rolling load rate, Dell EMC recommends the use of
coverings, such as plywood, to protect floors during system roll.
l
Floor tile cutouts weaken the tile. An additional pedestal mount adjacent to the cutout of a tile
can minimize floor tile deflection. The number and placement of additional pedestal mounts
relative to a cutout should be in accordance with the tile manufacturer’s recommendations.
l
Take care when positioning the bays to make sure that a caster is not moved into a cutout.
Cutting tiles per specifications ensures the proper caster placement.
