Floor load-bearing capacityStorage arrays can be installed on raised floors. Customers must be aware that theload-bearing capacity of the data center floor is not readily available through a visualinspection of the floor. The only definitive way to ensure that the floor is capable ofsupporting the load associated with the array is to have a certified architect or thedata center design consultant inspect the specifications of the floor to ensure that thefloor is capable of supporting the array weight.CAUTIONl Customers are ultimately responsible for ensuring that the floor of the datacenter on which the array is to be configured is capable of supporting thearray weight, whether the array is configured directly on the data center flooror on a raised floor supported by the data center floor.l Failure to comply with these floor loading requirements could result in severedamage to the storage array, the raised floor, subfloor, site floor and thesurrounding infrastructure should the raised floor, subfloor or site floor fail.l Notwithstanding anything to the contrary in any agreement between EMCand the customer, EMC fully disclaims any and all liability for any damage orinjury 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 requirementsBest practice is to use 24 x 24 inch heavy-duty, concrete-filled steel floor tiles. If adifferent size or type of tile is used, the customer must ensure that the tiles have aminimum load rating that is sufficient for supporting the storage array weight. Ensureproper physical support of the system by following requirements that are based on theuse 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 twocasters each that weigh up to 700 lb (317.5 kg).NoteCaster weights are measured on a level floor. The front of the array weighs more thanthe rear of the configuration.l Floor tiles and stringers must be rated for a minimum static ultimate load of 3,000lb (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, EMC recommendsthe 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 thecutout of a tile can minimize floor tile deflection.
