Data centers

The modern centralization of servers and other active components also requires changes in the way these systems are cooled and protected. One solution is data centers.

What is a data center?


Modern data centers differ significantly from earlier versions of this type of installation for servers and other technologies. The original data centers were established on the main Internet connections since the 90s of the last century. Large data rooms were built mainly as perfectly secured rooms for surveillance, storage and sufficiently dimensioned communication links, especially optical ones. Parts of these rooms were then rented to users for their technology and Internet applications. Almost without exception, these centres had a double floor with a high load-bearing capacity under which all lines ran. Cooling was usually central, i.e. the room as a whole was cooled without taking into account the distribution of the heat load and without the possibility of effectively regulating the cooling of the individual distributors or part of the data room.
With the development of telecommunications, the new protocols and the increased capacity of the transmission lines, high-speed connections became easily accessible without the need to install a system directly at the main connection.
At the same time, there was a revolution on another front, in computing power and memory capacity. Processor performance increased rocket-like, multi-core processors and new operating systems emerged. The capacity of hard disks and other storage media was multiplied.
The operating systems of the servers used the available means for distribution to several concurrent applications, and from here it was only a small step to the division of a physical computer for several concurrently running operating systems, to virtualization.
Thanks to this, most companies today either run their applications on their own user-specific servers or use the services of increasingly popular virtualization and so-called cloud hosting. These two methods require a high density of installed computing power. Since these are mostly critical applications for the operation of companies and institutions, connections secured against failure, physical protection and, last but not least, controlled cooling are required. All these requirements are covered by the data center concept.
Over time, standards have been developed for the design and construction of data centres. The distributors are arranged in groups, usually in two rows 1200 mm apart (two floor plates of the standard double floor). The corridor between the distributors is enclosed and at the end there are sliding doors.  In very large data centres we also find partition doors within these units, which divide them into smaller areas.
The main product of our company for data centres is the RDA cabinet with a load capacity of 1800 kg in the form adapted for data centres. It is supplemented by other structural parts, such as roof panels of various types, sliding doors, including self-closing ones, etc.
At the same time, we also offer a complete range of raised floors for installations where their use is possible. The load-bearing capacity of the floors in the rooms for future data centres is particularly critical. If it is not possible to install a raised floor (insufficient clear room height, insufficient permissible point load on the floor, etc.), we offer an alternative in the form of cooling units with upper media supply and condensate drainage between manifolds. This progressive solution also offers a high installed cooling capacity with a small footprint.
By combining several manifolds into a single data center, cooling optimization is also required, among other things. An uncontrolled air flow is expensive and ineffective.
By using RDA distributors and data center components, it is easy and effective to build a complete data center. The most commonly used cooling methods are:
