Save costs and resources with SCHÄFER

Despite increasing server densities, it is possible to save energy and consequently costs in data centres.

To do so, the effective cooling capacity in particular must be directed precisely to the place it is needed.

Examples:

To make ice cubes, it isn‘t the entire house or the refrigerator that is cooled down, but simply the ice compartment!

Optimal planning of IT infrastructure has influence on...

Cold/Warm Aisle

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

Air-cooled solutions

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

(8)

Cold aisle enclosure

COLD SECTION

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

Cooling by means of a raised floor and the enclosure of cold aisles

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 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

(9)

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.

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)

By using 9 ventilation tiles SWAP PANEL 9 achieves an open area of 60 %.

SKYLINE

Enclosures – the solution for cabinets

of varying dimensions

Enclosures

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.

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.

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.

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 efficiency

*) Graph data are proximity data. To calculate cooling requirement, precise data are needed.

LOOPUS is a cold aisle enclosure with or without a raised floor. The warm air is sucked in, cooled over an integrated heat exchanger and fed back to the servers.

Why LOOPUS?

n The cooling units are regulated in the direct proximity of the heat source

n The outstanding feature of the LOOPUS operating

prin-ciple is its extremely low pressure loss in comparison to the raised floor solution

n The cooling capacity can be adapted more quickly to the actual requirements

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.

Energy supply

Reliable power supply safeguards

IT infrastructures and system components

Germany‘s power grid is among the most efficient worldwide. Its failure rate is lower than that of other leading Industrial nations. Nevertheless, in planning and organising your physical infrastructure, the failure risk should be minimised right from the outset. There are various approaches, depending on the desired availability of your IT equipment.

Regardless of whether your transformer station already provides a redundant power supply or you are just beginning to use a UPS configuration with an n+1 solution, we can help you to implement your redundancy concept inside the server/ network cabinets right up to the terminals.

Fire protection technology

Fire detection and extinguishing

To comply with fire protection standards, fire detection and extinguishing plans must be in place. A 3-stage safety concept can be helpful in accomplishing this:

Rack-based extinguishing – integration in the rack

n Easy-to-handle, space-saving 482.6 mm (19“) insert

n Integrated aspirating smoke detector

n 1 or 2 U

n Extinguishing agent: Novec™ 1230 N2

n Earliest possible, highly sensitive smoke detection n

Auto-matic system shut-down n Optimal fire suppression with gas.

Depending on the infrastructure, various approached must be pursued.

Room-based extinguishing – integration in the rack

n Extinguishing system covering the entire room (e. g. inside the enclosure in the aisle ceiling)

n Smoke detection in the rack

n Extinguishing system intended for all racks)

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 efficiency improvements and considerable operating cost reductions can be achieved with relatively little effort and expense! Cooling with water-cooled racks (closed system) Cooling method

A solution for a relatively homogenous computer centre layout. Performance depends on height of raised floor and air circulation planning. Optimisation possible by accurate sizing of server loads. Risk of hot spots if performance requirements approach borderline areas. Advantage over warm/cold aisle because the enclosure provides structural sepa-ration. Pay attention to pressure ratios in the cold aisle (could have a negative influence on the server). For several enclosures in one room, careful ventilation planning is required.

Practically a mini data center in itself. High level of heat dissipation possible. It should be taken into account that special solution for detecting and extinguishing fires may be required. Can be used in combination with classical room air-conditioning. Advantages of cold aisle enclosure. No raised floor necessary. Shortest possible air paths. Redundancy guarantees high availability.
