Redundant Cooling System Control

Continuously increasing the ICT technology density with ever-increasing loss of heat, cantered on data centre objects, puts high demands not only on the technological parts of refrigerant production and distribution, but also on the systems that monitor and control these technologies. Due to the requirements for control and regulation technology, these are usually highly sophisticated technical solutions, using state-of-the-art technical and software tools of the world's leading manufacturers.

Technical characteristics cooling-control

The overall design of the MaR system must be designed to take into account the basic parameters of server room and data centre classes to ensure the redundancy in the required TIER class.

Each TIER (I-IV) category has specific requirements for the availability, reliability, mean time between failures and other aspects. Since the MaR system provides cooling control and monitoring, it is necessary to process this system to ensure the necessary cooling redundancy for the data rooms. In particular, so-called critical points of the system, i.e. SPOF (single point of failure), must be avoided so that a failure of one component does not cause a failure of the entire cooling system and consequently overheating of data rooms. Eliminating these critical points also means that most systems will be serviceable under operation. Last but not least, the possibility of manual control must also be taken into account in order to control the supply of cold even when a part of the control system fails.

Basic characteristics of redundant systems

  • Redundant power supply to both the technology and the MaR system
  • Element redundancy (N, N + 1, N + N)
  • Average downtime per year (from 28 hours for TIER I to 15 minutes for TIER IV)
  • Eliminating SPOF (single point of failure)
