A Bit of theory
The effective way to centralise servers and other active elements requires a change in the methods of cooling and protecting this equipment. The solution is – a data center.
What is a data centre?Modern data centers differ significantly from the early versions of this method of installing servers and other equipment. The original data centers have been established on the backbone of Internet connections from the 1990s. Large data halls were built primarily as a space perfectly protected in terms of security, uninterrupted power supply and with adequate capacity of mostly optical communication lines. The individual cabinets were then leased to users for their technical and Internet applications. These centres almost always had raised floors with high loading, beneath which were located all cabling and cooling systems. The cooling was mostly centralised so the entire room was air conditioned regardless of the distribution of the thermal load and without the possibility to effectively regulate the cooling for individual cabinets or the data hall.
With the development of telecommunications, new protocols and an increase in the transmission line capacity, high-speed connections have become available without the need to place the device directly onto the backbone connections. In parallel, a revolution took place on another front - processing power and storage capacity. Processor performance grew dramatically, multi-core processors began to appear along with new operating systems. Hard drives and other storage media multiplied in their capacity.
Server operating systems began to use available resources for sharing multiple, simultaneously running applications and from there it was only a small step to share one physical computer for running multiple operating systems simultaneously - for visualisation. As a result, most companies now run their applications either on their own servers dedicated to specific applications or use the services of the increasingly popular virtualisation and the so-called cloud-hosting. Both methods require a high density of installed computing power. Because these applications are often critical to the operation of businesses and institutions, it requires a fail-safe power supply, physical protection, and controlled cooling. All these aspects are covered by the concept of a data centre. Over time, a standard was established for the design and construction of data centres. Cabinets are placed in groups, usually in the form of two rows spaced 1,200 mm apart (two standard raised floor tiles). The aisle between the cabinets is then roofed and closed at the ends by sliding doors. In large data centres, dividing doors can also be found within these units, which split them down into smaller sections.
The main product of our company's data centre solution is the RDA cabinet with a load capacity of 1,800 kg in a version adapted for the construction of data centres. Other necessary components such as ceiling panels of various types, including sliding doors, as alternative self-closing etc., make a complete modular system. We also offer a complete range of raised floors for installations that allow their use.
The floor loading capacity is particularly critical in the rooms of future data centre. In cases where it is not possible to use the raised floor (low room height, insufficient permissible floor loading, etc.) we can offer an alternative, in the form of In-Row cooling units with top media inlet and condensate pump. This advanced solution offers an extra-large installed cooling capacity on a small footprint. By connecting multiple cabinets in a data center, the need for cooling optimization begins to arise, among other things. Uncontrolled air flows are costly and inefficient.
By using RDA cabinets and components designed for data centres, it is possible to assemble a complete data center easily and efficiently. The most common solution in terms of cooling:
Data center cooling principles
Our specialists will gladly help you choose the optimum solution for your needs.
By choosing the right type of cabinet and accessories, you can save significant amount of money spent on the operation of your equipment.
When selecting the most suitable arrangement it is necessary to take into account the type of cooling system (under-floor cooling, In-Row cooling units ...) and with regard to the cooling medium used, also select the outer part of the system.
Choice of the cooling medium must be done with respect to outdoor climatic conditions, the distance of the data center from the external units and the elevation between them. Depending on conditions, a water cooling with the appropriate addition of antifreeze or system operating with liquid refrigerant gas can be selected.
With regard to safety and redundancy required for service operations, it is necessary to design the complete system properly, both on the inside of the data center and on the side of radiators or condensers.
Furthermore, the requirements of humidity control must be taken into account. Humidity lower than 30% carries a risk of damage to the installed equipment by static electricity surge; high humidity can lead to condensation.
We offer cooling systems from leading manufacturers operating in this highly specialized field of data centres and telecommunication equipment cooling for many years. Thanks to the close cooperation and support of their development teams, we can offer you proven and guaranteed solutions.
Designing a functional, reliable, financially and operationally efficient cooling systems for the data centre is not an easy task and our specialists, who will recommend the optimum solution in terms of investment and operating costs, are fully available to you.
Distribution panels with management systems exist in many different models. Whether in terms of dimensions, where we offer solutions from the standard 19” panels to large vertical panels designed for house distribution systems, or in terms of different inputs (16A-64A, single-phase / three-phase). It is possible to choose from many product lines according to the required panel functionality (measurement of the panel as a whole unit or measurement of individual outlets, the control panel as a whole or individual outlet switching, additional monitoring functions temperature / humidity / door contact / water flood sensor).
We will be happy to advise you on choosing the most suitable solution.
