In the hot summer, 11 coups will help your data center cool down and reduce costs.

As the weather gets hotter, many small and medium-sized companies see their data center cooling systems reach their limits when they enter the summer. It is for data centers that are small and professional with extra capacity chilled water systems. Many IT departments say that the summer is too hot, I hope they will not have a server overheating and suddenly crash and shut down.

Many times, the actual capacity of the cooling system is not considered to be higher than the actual heat of the equipment. The optimized airflow may be increased to the installation of a new or additional cooling system. Some other things can also help. . Here are 11 tips, tricks and techniques that may not solve long-standing problems, but enough to help get your data center.

Tip 1: The server with temperature measurement is on the front. This is the only effective and most important measurement method for servers under the cool air. Have a reading at the top, and then set up a hot aisle-cold channel layout. If you find that the bottom area of ​​the rack is cool and there is space, try to rearrange the server to make the environment the coldest. degree.

Tip 2: Make sure to take full advantage of this frame pattern in any open environment and block the slabs in an unopened environment to prevent hot air entering from the front and rear of the rack. cycle.

Tip 3: If you have a raised floor, make sure the floor (or raised floor) is located in the most popular rack in the machine room. If necessary, rearrange or change to a different raised floor according to the matching airflow heat load. Be careful not to get the raised floor and CRACs (computer room-specific air conditioners) too close. This will allow the cool airflow to be immediately returned to the CRACs (computer room-specific air conditioner) and the equipment room to provide sufficient cooling air.

Tip 4: Check the opening of the floor. The opening of the cable in the floor opening is easy to make the cold air flow out from the opening and reduce the venting effect of the existing cold air in the cold aisle. Air containment to minimize this problem.

Tip 5: If possible, distribute as much as possible and load the heat into each rack to avoid spreading "hot spots". Remember to move your server and hottest server to a cooler area before checking the temperature at the top, middle, and bottom of the rack. 6

Tip: If you have an overhead line systems, to ensure that the cold air outlet slot is in front of the rack cabinet and returns are at the rear. The ceiling vents I have seen have been misplaced and the room is hot, but the ability to cool the system has not been exceeded. Some basic plumbing work may help solve this problem.

Tip 7: consider adding temporary "rolling" type cooling unit, when hot exhaust gas into the outer region of the time, the exhaust pipe may be the excess heat of exhaust gas discharged from the CRAC. The laying of the hot exhaust pipe will discharge heat in the control space of a certain area.

Tip 8: When the room when no one, turn off the lights. This can save 1 to 3 percentage points of electrical and thermal load, while at one edge of the cooling situation, the temperature can be lowered by 1 to 2 degrees.

Tip 9: Check if any equipment is still blocked, or electricity when they did not work. This is a fairly common phenomenon and there is a simple solution: just turn it off!

Tip 10: If you still see the cold aisle 80 degrees Fahrenheit, do not panic! Yes, although it is well known that the temperature exceeds the "standard" of the Fahrenheit 68-70 data center, it may not be as bad as you think the server. If the highest reading is below 85 degrees Fahrenheit (worst case), your server is relatively safe. Most modern servers have higher operating temperature levels, allowing them to operate safely above 80 degrees Fahrenheit, even up to 90 degrees Fahrenheit. Although not ideal, this is the specification published in most manufacturers. Many servers have internal temperature displays that are accessed through management software.

Tip 11: If all else fails, there is a back-up plans to close at least critical systems. In this way, more critical servers can continue to operate. But remember to find the key system areas. This is better than accidental shutdown of some random systems.

At this point, 11 tips for cooling the data center can be said to have been sorted out, maybe not really solve your heat load problem quickly, or completely beyond the capacity of your cooling system, sometimes only improve Airflow may increase overall efficiency by five to twenty percent. This may help you through the hottest days until you can upgrade your cooling system. In any case, it will reduce your energy costs, which is always a good thing.
