In data centers there is a debate about whether to use hard flo

  • woodcore raised floor panels has been a standard feature in data centers for many years, and it was installed in at least one or more rooms in nearly all first-generation data center buildings. The raised design was intended to provide the necessary space for cooling as well as power and communications cabling, while also allowing for easy access to all of the components. During the last few years, however, there has been a shift toward hard flooring, with cooling and cabling installed above the floor.

    The following are the most important factors to consider when deciding which flooring to use:
    Power density: For today's higher-density deployments, a raised floor may not be able to provide sufficient cooling due to its limited cooling capacity. Even when cooling is adequate, many older legacy cooling systems can be inefficient and wasteful in terms of the amount of carbon dioxide emitted by the energy required to operate them. In both cases, overhead cabling and solid flooring may be preferable alternatives to carpeting and tile.

    Rack rearrangement occurs on a regular basis and to a high degree. When it comes to facilities such as certain co-located data centers, the cost of installing overhead cables and ductwork, as well as the cost of reconfiguring the infrastructure to accommodate changes, may be so great that raised floors may continue to be the more cost-effective option for the foreseeable future, so long as operational security and safety can be ensured. When it comes to long-term budgeting, overhead access and solid flooring should be taken into consideration.

    "Back then" and "Now" in the context of raised floors

    The raised floor was created in order to provide specific functionality for early data center facilities. As the equipment has evolved, so have the requirements, which are as follows:

    Distribution of cold air for the purpose of cooling information technology equipment –Equipment was available in a wide range of shapes and sizes when it first became available. It is much easier to plan where the equipment will be located and define the required airflows at this point because the equipment types are fairly standard. As a result, the need to relocate cooling pathways is either greatly reduced or eliminated entirely.

    Tracks, conduits, or supports for data cabling are all examples of this. Initially, large multi-conductor copper cables were used to connect computer cabinets. It was necessary for these cables to be as short as possible in order to avoid signal degradation. In today's data centers, interconnection cables are made of either fiber optics or high-bandwidth ethernet, which can transmit data over much longer distances. Short-distance access, as a result, has been reduced to an almost non-existent extent.

    In the early days of data centers, IT equipment was frequently hard-wired, with power connections entering from beneath the floor. The circuits were easily accessible by simply removing floor tiles from the subfloor. Cabinets are now designed to allow for power connections to be made through the top. In comparison to underfloor conduits, the power distribution units (PDUs) and overhead busways currently in use provide much easier access and are much more convenient.

    A copper ground grid for the purpose of grounding electrical equipment –Originally, it was necessary to have solid grounding between interconnected equipment, so equipment was typically bonded to a copper signal reference grid to ensure proper grounding. Currently, the function of copper and optical fiber communication technology is not dependent on the presence or absence of grounding between devices. Every branch circuit is equipped with a grounding wire, which ensures the circuit's overall safety.

    There is no longer any need for a raised floor to accommodate utility piping or running chilled water because the majority of the functional requirements have been met. A raised floor, on the other hand, may be necessary for some newer cooling designs that still require water to be distributed throughout the IT space.

    When is it preferable to have raised floors?

    In some situations, raised floors may still be preferable. For example, in the following situations:

    The use of chilled water in the IT space is necessary when the cooling system requires it (as previously discussed).

    It is used in low-density data centers where it would be difficult or impossible to predict the row locations of devices in advance, such as some caged co-location spaces.

    In neither of these instances does the raised floor require a significant amount of depth. Woodcore raised floor panels systems, on the other hand, can be extremely expensive to install when compared to traditional hard flooring. As a result, data center designers and builders should carefully consider all of the options available today, rather than making decisions based on previous projects.

    When is it preferable to have hard floors?

    All types of modern data storage facilities and server rooms, including those with hard floors, are routinely constructed in this manner. Hard floors are now preferred in the following situations:Because of the unprecedented demand for massive storage capacity, the number of hyperscale data centers is increasing at an exponential rate. Large data centers with high density that can benefit from new fresh air systems and hot-aisle containment techniques. When it comes to smaller data centers, the necessary space to construct ramps up to the raised floor level is not available. confined spaces with insufficient headroom, in which the floor cannot be raised sufficiently to accommodate the required power density
