IT equipment performs precise calculations and copes with complicated tasks. To ensure its stable, smooth, and durable operation, it is vital to create optimal environmental conditions. Network hardware is sensitive to any change in environmental indicators. For example, condensation settles on circuit boards when the atmosphere is too wet. This is the main reason for creating the ideal server room temperature and humidity, which stands as a vital provision for any data center.
The smoothness and durability of the performance of network devices highly depend on the temperature regime. Overheating of servers, processors, and other active hardware results in improper performance in the best case. In the worst case, overheating can lead to equipment downtime and malfunction and completely disable devices.
According to the server room temperature standard, computing hardware works smoothly with an indicator being about 72°F. When hardware is placed in rooms in which this temperature is maintained, devices work durably and sustainably; no breaking or increased deterioration is observed.
To guarantee the recommended server room temperature, system administrators should take into account the following factors:
Generally, it is recommended to pick premises without windows for the server room arrangement. Also, note that each type of lighting emits a certain amount of heat. The more cabinets or other occupants are placed on the premise, the more heat will be produced.
System administrators must treat these factors when calculating the optimal server room temperature and selecting the needed cooling system.
Both dry and wet air is critical for IT equipment. The rise or fall of this indicator can lead to the failure of processors, chips, and other components of electronic devices.
So, over-low humidity when the air is too dry leads to the accumulation of static electricity. Damage to network hardware can be caused by both the accumulated charge and a possible electrical breakdown between two metal surfaces. Over-high humidity results in condensation on cold surfaces. Moreover, too low or high humidity can result in fires.
The optimal humidity level is about 40%-50%. This humidity level does not allow the water vapor to condensate on circuit boards.
The need to regulate and create particular environmental conditions is determined by apparatus vulnerability. Computing devices require satisfying certain environmental parameters to guarantee smooth functioning and reliable datum storage and processing.
With proper implementation of standards through careful site design and system deployment, the data center’s reliance on traditional mechanical cooling methods is reduced. This reduces cooling costs and increases equipment reliability. Thus, it is vital to maintain the ideal temperature for data center and monitor the level of humidity on the premises. Every published standard or collection of ASHRAE recommendations has gone through a rigorous peer review process. Particular efforts have been made to assess the views of parties interested in or referred to in the proposed standards. The result of the work is the finished product, obtained on the basis of the consent of all interested parties. The agreement of the parties to these standards is voluntary since only the regulatory body has the authority to insist on the adoption of a particular standard as mandatory. However, ASHRAE’s standardization process itself has proved so authoritative that many other standards have been developed from it.
A large number of sensors are offered on the modern market to monitor the required level of environmental parameters. There are models designed for placing in rooms or directly server cabinets. Installed sensors are connected to apps that manage their operation. The following tools are widely used by system administrators to monitor the atmosphere remotely:
All apps send alerts in the event of the rise or fall of atmospheric parameters to the control panel.
The following solutions are applied to cool server rooms and hardware.
This is an additional panel installed on the premise to achieve better room cooling. Several fans can be installed and directed to different parts of the room to force the air to circulate in the right direction.
These are special metal constructions for fan installation. There are bodies of different sizes and types, which allows placing different models of fans and using them for both room and server cooling.
This is a set of tools designed for fastening fans to walls or roofs.
Another technology implies placing room occupants according to special maps used to create cold and hot air aisles. When circulating through these aisles, the air exchanges heat effectively and cools down naturally.
Such cooling systems are used to control the environment inside premises and sever furniture. They allow adjusting environmental parameters to achieve the optimal level for computing hardware functioning.
Due to the use of fans, sensors, and hot/cold aisles, it is possible to adjust the environment of each room to the required standards. Compliance with set norms of atmospheric factors inside data centers will prolong system functioning and ensure its smooth operation. Network equipment is used to store datum and perform complicated computing tasks. Electronic devices are sensitive to condensation and static electricity, which are caused by improper environmental conditions. The violation of environmental standards for data centers will lead to system malfunction and downtime. To create and maintain the optimal atmosphere inside data centers, fans, vaporizers, and chillers are used. Sensitive sensors allow monitoring indicators remotely and alert when atmospheric parameters are not satisfying.
Every system administrator knows how important it is to maintain certain environmental conditions in server rooms since computing hardware is vulnerable to changes in the atmosphere. The Ashrae standard was developed to systematize this scope of indicators. This is a set of rules adopted for different types of premises to ensure optimal ventilation conditions and improve the quality of building use. The document determines the optimal data center temperature and humidity standards. The rise of the document goes back to 1895 when the Association of American Engineers started to develop norms for heating and ventilation in all sorts of buildings. The society dealt with the development of guidelines for air conditioning, refrigeration, and heating. In 2004, the association created a core set of guidelines for heat allocation in data centers. The second and third editions were adjusted to modern hardware and re-published. Each time, new information was added to the document. Amendments were related to the classes of servers and other computing hardware that could operate at ever higher allowable levels of environmental indicators. Nowadays, the standard has a separate chapter devoted to the regulation of the environment in data centers.
According to the ASHRAE standards, they distinguish between four main classes of equipment:
Most of the devices in modern data centers fall into Class A1 or A2, although an overwhelming number of hardware manufacturers, such as Dell, are involved in the production of hardware of Class A3 or A4. Manufacturers are more likely to offer a wider range of A3 and A4 devices due to a rich assortment of data center designs. Statistical studies show that in the case of properly designed servers, the failure rate does not increase when operating at high temperatures, and reliability does not decrease. But, keep in mind that backward compatibility of the ASHRAE guidelines with legacy hardware is not possible.
That is, a new Class A3 or A4 server will perform just fine in a more complex environment, but deteriorated Class A1 hardware will not function reliably in more challenging environments. Besides, ASHRAE guidelines allow devices to operate under more difficult operating conditions for short periods of time, making it easier to maintain system continuity in the event of a cooling problem.
A server room’s recommended temperature range is typically between 64°F and 80°F (18°C to 27°C). This range helps ensure optimal performance and longevity of the equipment while preventing overheating.
If the temperature exceeds 80°F (27°C), it can start affecting server performance and stability. Temperatures above 85°F (29.4°C) can become critical, potentially leading to hardware failures and data loss.
The normal humidity range in a server room is typically maintained between 40% to 60%. This range helps prevent static electricity buildup and reduces the risk of equipment corrosion or condensation. Humidity levels below 40% can increase static discharge risks, while levels above 60% might lead to moisture-related problems. It’s essential to keep the humidity within this range to ensure optimal performance and longevity of the IT equipment.
ASHRAE server room temperature standards is typically between 18°C to 27°C (64°F to 81°F). Humidity level of 20% to 80% RH. This range ensures optimal performance and reliability of data center equipment, balancing the need for efficiency with the protection of sensitive hardware.
