6 The right cooling concept Make your data centre fit for the future 30 The right cooling concept depends on the effective cooling capacity needed per rack and the required level in the given spatial conditions Effective cooling capacity per rack in kw Efficiency Possible solutions Air-cooled solutions Water-cooled solutions Coolant-based solutions COLD SECTION Racks SWAP PANEL9 COLD SECTION + SWAP PANEL9 COLD SECTION + LOOPUS as Open LOOP COLD SECTION + LOOPUS as Closed LOOP UNIQLE LOOPUS (CW) LOOPUS (DX) Row-based solutions Cold/Warm aisle solutions Rack-based solutions 6

7 Air-cooled solutions Cold/Warm Aisle up to 4 kw/rack Cold/Warm Aisle Modern rack cooling concepts provide efficient server cooling while keeping electricity consumption low. The principle all these concepts are based on involves directing the cold air to the servers as precisely as possible. n The racks are set up face to face in rows on the raised floor (cold/warm aisle) n A precision cooling device feeds cold air into the raised floor via ventilation panels at defined points n The cold air is fed to the servers from the front through passively ventilated cabinets doors n Behind the racks, the warm air is extracted via the ceiling by a cooling device and cooled down n This cold air is returned to the raised floor and back into circulation n The cold air aisles in front of the cabinets and the warm air aisles behind them are clearly separated from each n This cooling principle is based on the precise routing of air to achieve a greater cooling effect 7

8 Air-cooled solutions Cold aisle enclosure COLD SECTION Optimum cold-air routing The purpose of an enclosure is the complete structural separation of the cold aisle in front of the servers and the hot aisle behind the servers. n The aisles between them are fitted with ceilings and sliding doors to enclose the cold aisle n The cold air directed through the raised floor is exclusively released into cold aisles n Enclosure of the cold/warm aisles facilitates the targeted COLD SECTION for preventing air short circuits (warm and cold air mixing together) n Economical solution n Scalability of additional cooling (LOOPUS) n Raised floor enables cooling capacity to be adjusted n Easy assembly n Optional extension to cold/warm aisle n Enclosure creates structural separation routing of cold air from the raised floor to the hotspots in the cabinets and the warm air back into the cooling cycle via the rear of the racks n Warm and cold air in the data center is effectively prevented from mixing up to 20 kw/rack Cooling by means of a raised floor and the enclosure of cold aisles 8

9 Air-cooled solutions Raised floor system SWAP PANEL 9 The variable option for ventilation Modular raised floor panels with exchangeable segments which allow a variety of ventilation options and an even more precise concentration of cold air at individual hotspots are a very useful addition to any enclosure system. Within the overall concept of directing cold and warm air in the data center as effectively as possible to achieve needs-related cooling requirements, they provide greater flexibility and add the fine tuning to the air supply for the cold aisles. By using 9 ventilation tiles SWAP PANEL 9 achieves an open area of 60 %. SWAP PANEL 9 Modular inserts in three variations, size: approx. 200 mm x 200 mm n Air-flow elements (approx. 60 % open area) n Cable routing elements n Solid elements (standard and heavy duty) 9

10 Enclosures SKYLINE Enclosures the solution for cabinets of varying dimensions The SKYLINE Enclosures Server cabinets often come from many different manufacturers and in different dimensions. With our flexible SKYLINE Enclosures, it is possible to put a roof over existing cabinets rows and IT structures that have grown together over years, regardless of their manufacturers. n Enclosure of cold/warm aisles with different widths and heights n Profiles with individually measured Sandwich panels are fitted to close the gaps between the cabinets n For cabinets of varying height, the spaces up to the aisle ceiling are also compensated with sandwich panel profiles n The modular system facilitates on-site handling and the flexible extension of the enclosure, if required Wall and ceiling elements and doors from the SKYLINE range can be placed over existing server cabinets (see above). The result is a cold aisle enclosure that meets the latest standards of modern, energy-efficient cooling (see below) Air Tube Switch: controlled cooling for switches combined with the separation of cold/warm sections in racks The Air Tube Switch enables cooling air for switches to be routed with precision. It can be installed in 800 mm wide racks with 19 at the front and rear. The use of the Air Tube Switch enables switches to be mounted adjacently without any mutual thermal influence. 10

11 Rack-based solutions water-cooled Rack-based, water-cooled server cabinet solution Closed LOOP This highly efficient cooling concept has a side cooler mounted directly next to the rack or between two server racks which are closed both at the front and rear. Cooled air is fed into the closed server rack through the air vent slits in the rack s side panels. The warm air given off by the servers is sucked in on the rack s rear side by the side cooler. This circulating air is then cooled by an integrated heat exchanger and fed back into the rack over its entire height. Why Closed LOOP? n The Closed Loop System is a self-sufficient mini data center n Its high heat load dissipation per rack of up to 30 kw enables it to fulfil all requirements of high availability and reliability n This guarantees the highest levels of space and energy The coolant-based cooling system (DX) is used when entire systems require effective cooling capacities of approx. < 50 kw. For reasons of economy, the water-cooled solution (CW) is only used when the effective cooling capacity for the entire system exceeds > 50 kw. 11

12 Rack-based solutions water-cooled Row-based, water-cooled server cabinet solution Open LOOP with COLD SECTION LOOPUS is a cold aisle enclosure with or without a raised floor.

15 Rack-based solutions coolant-based Coolant-based server cabinet solution with side cooler Compressor Condenser Evaporator Expansion valve External cooler Side cooler Compact, coolant-based side coolers are integrated into the rack rows, cooling either one individual rack or the cold aisle of a rack row. The heat transfer fluid (coolant R410A) is circulated in a cycle (see diagram above). Driven by a compressor, it absorbs thermal energy from the rear of the server and passes it on to the external cooler unit via an evaporator. The system is available as an open (Open LOOP) or closed air circuit (Closed LOOP) and suitable for use in smaller server rooms. Heat dissipation capacities of up to 20 kw are possible. The coolant-based cooling system (DX) is used when entire systems require effective cooling capacities of approx. < 50 kw. For reasons of economy, the water-cooled solution (CW) is only used when the effective cooling capacity for the entire system exceeds > 50 kw. 15

20 The right cooling concept Any optimization in the data center is based on a sound currentstate analysis, in which all relevant parameters regarding energy consumption and thermal loads are determined and evaluated. This will then reveal what measures are required for achieving effective optimisation and improving consumption figures. Significant improvements and considerable operating cost reductions can be achieved with relatively little effort and expense!
