The overheated data center can cause data corruption, so it is important to cool the data center computer room. There are 12 effective methods to cooling the data center computer room. Today we will focus on 6 methods of them, and the other 6 methods will be highlighted in the next article.
The data center's temperature standard range is generally 70 ~ 72 (Fahrenheit unit). When you find that the data center ambient temperature has a significant upward trend, or has exceeded the above standard range, don't be panic in this situation, because this may not be as bad as you think. Sometimes the simple data does not represent the actual situation, or it may be caused by uneven heat dissipation in a certain part of the temperature, while other parts of the temperature are still within the controllable range, so be sure to check it carefully. And even if the temperature rises to 80, it is reasonable according to the temperature range recommended by the latest TC 9.9 guide provided by ASHRAE.
Everyone knows that there is a part to suck cold air in front of the server, where we can measure the temperature. We can measure the values of the top, middle and bottom of the server rack separately. If you have experience in measurement, you should know that the temperature at the top of the general server is the highest. If the bottom area of the server rack is cold, try relocating the server to the coldest area near the bottom of the rack, be sure that the data center has an open server rack space.
Be sure to use a blank board to block all open but unused space on the front of the rack. This will help prevent hot air from the rear to circulate to the front of the rack again, causing high temperatures in front of the rack.
Don't pay special attention to the temperature at the rear of the server rack, don't try to install the random fan to the rear of the rack, even if the temperature at the rear has reached more than 100, because if you want to cool the rack, the rear part will only blow more hot air into the cold aisle, causing the overall temperature to rise sharply.
If there is an elevated operating floor in your data center, make sure that the floor grille or perforated bricks are properly placed in front of the hottest rack. If necessary, consider relocating or replacing different floor grilles to match the airflow to the heat load. Take extra care not to place the floor grille too close to the CRAC, otherwise the cold airflow will be "short-circuited" back into the CRAC and take away enough cold air from the operating environment space/rack section.
Please check the movable floor in your enterprise data space cabinet. If not necessary, the cable opening on the floor allows air to escape from the raised floor ventilation system and reduces the available cold air to the floor vents in the cold aisle. This problem can be minimized by using an air-sealed container brush collar kit.
The remaining six methods will be presented in the next article. You can also choose a high quality heat sink for your data center.
