In a standard raised floor cable setup. Horizontal and vertical bars are placed on the actual floor which creates a raised grid like structure. Inside this grid, flat panels are fixed and under this raised surface, all tupe of cabling is laid out. In some cases the chilled air is also pumped through this false flooring.
Raised floors is a good in terms of aesthetics as long as the complete cabling goes beneath the false raised floor and reaches the servers through the bottom cable sockets of Racks. So, it is mostly invisible from outside making the place look cleaner and neat. The other benefits of Raised Floor cabling are heat management and easy access to the hidden cables.
Cables in a raised floor setup should be run through the raceways ( cabling channels ). This helps protect them from interferences caused by power cables, security devices and fire suppression systems which are also generally laid down in the same raised floor area. Raceways also help in the distribution of cool air.
Almost all type of cabling such as structured network cabling, electrical cables, KVM wires and if required telephone wires, all go through this grid and pass through the bottom of each rack location power receptacles. Then these wires are passed into and connected through the Rack patch panels. The child air is pumped to the room through the placement of solid and perforated floor tiles.
And as discussed earlier using a raised floor setup one can make most of the patch cords and pathways invisible by keeping them away from the sight. This not only enhances the aesthetic value of the room but also makes the devices less prone to damage or getting manhandled.
But, one problem which we face most often with false flooring deployments is that, if your datacenter is scaling up rapidly and you have not planned the growth properly while deploying the datacenter, then there is a chance of the false flooring not taking the load of the equipments. But with a bit of planning such kind of issues can be tackled easily.
