The main concern in a data centre is the IT equipment health and for this reason, this method has been developed in order to improve power efficiency by improving the IT equipment health. The domino effect is produced when better management of the open surfaces in the raised floor and racks have a positive effect on the IT equipment health, which subsequently provides opportunities to improve power efficiency improvements.
The Domino Effect
Let us walk through our Method and Process
Know the health of the it equipment
Know the efficiency
Improving IT equipment health

The process was developed taking into account the three fundamental factors of simplicity, time and investment. Simplicity is the driving force behind the process, which enables the time required from data collection to when the solutions are put into practice to be as short as 48 hours.
However, simplicity is shown in that the type of solutions to be applied are the most basic on the complexity scale, attempting to make the solutions comply with the lowest possible investment.
First Visit and First Report
During the first visit, temperature readings are taken and also aperture management at raised floor and rack levels. To this end, data is taken on Hotspots, Coldspots, Esd, Deltat T, Bypass Airflow and Recirculation, amongst others.
Under normal conditions, the first report is issued 24 hours after the visit, which means that the results correspond to the actual room conditions.
The first report details the number of Hotspots, Coldspots and Esd under a full study of temperatures shown in Delta application that reveals the uniformity of room temperatures.
The first report also presents the Bypass Airflow and Recirculation percentages, or in other words, the efficiency status with respect to air flow.
Lastly, the first report provides a list of products that must be installed in order to reduce the Bypass Airflow
Delivering And Installing Products
Product delivery time is subject to the actual room condition, but under normal conditions, products are delivered within 48 hours of the end of the first visit.
The speed with which products are made available enables solutions to be applied in record times with respect to the start of the project.
The first issued report provides information relating to product installation. In this way, it suggests the order in which the solutions should be applied, together with the safety measures to be adopted.
The types of products to install will vary from one room to another, but the products always form part of a batch of already established products that were previously defined by both parties.
Second Visit And Second Report
After product installation and the application of the proposed solutions, a second visit enables the room status to be established with respect to IT equipment health and with respect to air flow management.
For this reason, it is verified to establish by how much the Hotspots,Coldspots, Esd, Bypass Airflow and Recirculation have been reduced or eliminated.
Under normal conditions, the second report is issued 24 hours after the visit, which means that the results correspond to the actual room conditions.
The main goal of the second report is to establish how the air flow management improvement (Bypass Airflow & Recirculation) has managed to reduce the equipment inlet temperatures and make them more uniform.This result can be quite clearly seen by a full study of the Temperature Deltas in the room that show the improvement with respect to IT equipment health as well as with respect to air flow management.
Finally, the second report provides information on CRAC unit adjustments, together with steps to take in the future.
