Success story

An energy-saving technology for cooling servers has been created in Russia

7 Apr '21
The Ekaterinburg-based Terkon-KTT company has established the production of virtually silent micro data processing centers (micro data centers), which do not overheat and do not require additional air conditioning.

A feature of the product is the used passive cooling system based on the development of the Soviet scientist Yuri Maidanik. It is based on contoured heat pipes (CTT or tercones), which provide silent heat dissipation.

The use of KTT allows you to build a micro data center, which, in comparison with traditional systems, consumes 20-30% less electricity for cooling (per unit of installed IT load) and 5-20% less for the operation of server equipment, since the fans in the servers will work for more low revs, the company said.

According to Arkady Ivanov, General Director of Terkon-KTT, the products are primarily designed for representatives of medium, small and micro businesses who are not ready to resort to the services of cloud providers, for example, for security reasons.

Currently Terkon-KTT is assembling silent micro data centers for the first customers. Among them is the Moscow College of Creative Industries named after L. B. Krasin (Moscow) and the Yekaterinburg metallurgical company Uralprommetall. In addition, negotiations are underway with a number of large telecom operators.

Terkon-KTT offers three types of micro data centers: open and closed (if you need protection from dust and moisture) with a dry cooler (dry cooler), and closed with an air conditioning system. The micro data centers of the company have restrictions on the maximum temperature regime in the room: no more than +25, taking into account heat gains for a system with a dry cooler, and no more than +35 when used with an air conditioning system. The maximum dry bulb temperature of outdoor air is +42. There is a limit on the total heat removal capacity: up to 20 or 30 kW, depending on the type of device.

When organizing a micro data center, the company uses standard server cabinets designed for 42 units. Servers are selected according to the needs of the customer. It can be equipment from AIC, HP, Dell, IBM, Supermicro, ICL-techno and other, including domestic, vendors.

As explained in Terkon-KTT, a micro data center based on heat pipes per rack is comparable in cost to competitors, or slightly cheaper. However, since KTT is mounted directly in servers, such a cooling system does not take up much rack space, due to which the maximum server density is 30-50% higher. That is, in the most optimistic scenario for organizing a micro data center of the same computing power, instead of two server cabinets with all the stuffing, one will be required. Thus, the organization of the micro data center Terkon-KTT will cost the customer up to two or more times cheaper, taking into account the space savings in the server cabinet, the company notes.
