1 Climaveneta for Data Center The Milestone Of Green Data Center Cooling Technology

2 The future of data centers brings both advanced technologies and exponential data exchange that strongly increase heat loads per square meter. Structural limits result in higher and higher power densities affecting the development and design of server rooms. 2 l 3

3 Energy efficiency is crucial in data centers that require the latest cooling technologies to ensure the reliability and high performance of these critical applications. Server usage in both upgraded and newly designed data centers will, over time, lead to increasingly higher performance that eventually will result in higher density power loads. The data center environment is critical and requires a guarantee of reliability, device safety and modularity. Preparing for the modular infrastructure evolution, the IT room has several standards, classifications and certifications to comply with. The key factor that must be continuously improved is energy efficiency to cope with more demanding OPEX requirements, and the global footprint, which greatly affects CAPEX. Virtualisation, Cloud Computing and Internal Redundancy also greatly contribute to server room development with many powerful and concentrated servers creating racks exceeding 40 in less than one square meter (or 10 square feet). Cooling such loads is a serious challenge for the air conditioning industry and only solid technological innovations backed by R&D and experienced staff can provide the right solutions. The answers lie in the use and combination of the most sophisticated technologies such as MAGNETIC LEVITATION and FULL ELECTRONIC MODULATION cooling equipment. As a race car needs an experienced driver, high tech components require superb design capacities as well as a deep understanding of the application's requirements. Climaveneta has a full range of cooling solutions that include state of the art, efficient and reliable cooling technologies for ICT environments. Product Heat Density Trend Chart Heat load per equipment footprint - watts/ft Heat load per equipment footprint - watts/m 2 Communication equipment (frames) Servers & disk storage systems (1,8-2,2m tall) Workstations (standalone) Tape storage systems Microproccessor performace growth, even though compensated by increased efficiency, lead to the growth of power generated density. The evidence is such that, to represent the phenomenon, a logarithmic scale is necessary.

5 for data center efficiency Based on a 40-year experience in providing high efficiency cooling solutions, Climaveneta's solutions: Reduce operating costs The growing energy demand in modern data centers implies that every energy improvement allows for a significant reduction in OPEX (operating costs). In infrastructures working 24 hours per day, 365 days per year, over an average of 10 years, this accounts for the largest proportion of overall costs. Use the available power capacity in the best way Many facilities, especially in crowded urban areas, cannot install more servers because power feeds are at capacity. In these situations the key option is to improve the energy performance of the whole data center. Optimise areas A green, energy efficient approach to data centers has positive implications also for optimising space. It allows more effective use of the data center, concentrating cooling units along the walls, reducing waste due to cooling dispersion and delaying the need of building new rooms. Increase sustainability Growing digitalization and consequent energy consumption transform data centers into a very critical application regarding TEWI. Intelligent energy management is crucial not only for profitability but also for sustainability. Ensure reliability and extended lifetime Reliability is a key word when it comes to infrastructures of IT operations. Good server operation mostly depends on a perfect 24/7 cooling system. This ensures that servers are not exposed to potentially dangerous warm air that can result in thermal stress which decreases the IT equipment lifetime.

6 The awareness of data center requirements and the commitment to improve their energy efficiency has led to the development of dedicated indeces for these applications. All Climaveneta solutions are developed to optimise these metrics, allowing for a transparent evaluation of the real benefits offered by our approach to HD. Data center cooling & power load consumption Power and cooling represent the lion's share of the energy consumed in a data center, although they are not directly linked with the value adding operations of the data center. Accurate measurements of heat loads are the essential base for highly efficient green data center design. 55% Power and cooling 45% IT load Data center power consumption by apparatus 50% 45% 40% 8% Chiller IT equipment 35% 30% 25% 20% 15% 10% 5% 0% 6% 32% 30% 18% 5% 1% 1% Power distrib. units CRAC Humidification UPS Lighting Switchgear/generator 6 l 7

7 CAPEX Capital Expenditure The data center is a valuable asset for a company. All expenses relating to the infrastructure, especially high-tech solutions, remain within the company by adding value and extending the life span of the data center. OPEX Operating Expenditure Running costs of a data center operating 24 hours a day, 365 days a year for an average of 10 years, are crucial for those who must manage it. Even a small saving becomes very significant over time. This justifies even very high initial investments and justifies an anticipated system refurbishment, aimed at improving their efficiency. T.F.P. IT.E.P. % P.U.E. PUE Percentage of effectiveness = Total Facility Power / Equipment Power It considers the overall energy efficiency of the data center, measured as the ratio between total absorbed power and the power needed by the servers. As only energy used to transfer data creates value for the data center, a ratio close to 1 would represent the condition of optimum efficiency. Most data centers have a PUE between 2 and 3, excellent values are between 1,2 and 1,5. DCiE = 1/PUE x 100 Reciprocal of PUE, DCiE shows the % of power absorbed by IT infrastructure, compared to the overall data center consumption. Values close to 33% are usual for traditional data centers. DCiE of 66% reflects a very high energy efficiency. D C i E 33% 66% 51% 42%

8 Driven by increased data exchange, rising power densities and heat levels, data center design has changed dramatically over time. Cooling devices should therefore evolve together with data center changes ensuring: High flexibility Over the years, data center design has been continuously changed from the original design, including important changes in terms of: a Shape & architecture a Computing capacity a New technologies, always adopting the latest rack and server solutions a Heat dissipation Great Scalability Data centers require scalable design to: a Manage different heat loads for different areas a Manage an increasing heat load over time a Accomodate new areas to be cooled Climaveneta best practices Extensive research in this application has resulted in some best practices, which are a must for an efficient data center. Climaveneta solutions are designed to perfectly fit with this approach. Optimised air flow management Optimised air flow design, directing cold air through the raised floor to form cold aisles in front of the rack air intake. 8 l 9

In facing the cooling problems only smart solutions can avoid the disaster of shut-down while limiting CAPEX and OPEX. Reliability must look at a full 360 view.

10 Climaveneta HPAC solutions are adaptive cooling systems based on actual data center heat load requirements (/rack). Designed to achieve unparalleled efficiency perfomance and total reliability, the wide range of Climaveneta high precision solutions provides customers with the answer for every kind of data center. density zone < 5 /rack Hot/Cold aisle An easy, fast and long-lasting solution; the hot & cold aisle is the basic and essential concept that drives the layout of all data denters. a Through the raised floor, air can be easily delivered exactly where required (in front of the rack) allowing easy management of redundant cooling units. Cold Aisle Rack Rack Cold Aisle Rack Rack Cold Aisle a Flexible design, providing maximum freedom in accommodating new rack distribution or even major infrastructure changes. 32,2 C 26,7 C 21,1 C 15,6 C 10 C a Lowest CAPEX allows more investment in more productive equipment. 10 l 11

11 density zone /rack density zone > 25 /rack Aisle Containment AISLE CONTAINMENT prevents the HOT & COLD air from mixing in the upper section of the racks, guaranteeing homogeneous air flow. a No mixing between Hot & Cold air streams in order to avoid energy waste. a Additional 15% energy saving depending on the data center layout. a Quick and easy solution with low initial investments. a Complete integration with existing perimeter CRAC units. a Immediate energy benefits. Aisle Containment + Localised Cooling to manage hot spots CCD (Climaveneta Cooling Door) & CRC (Climaveneta Rack Cooler) guarantee ideal integration to manage HOT SPOTS caused by new blade servers, providing extra local cooling exactly where it is needed. a Extra cooling only where required. a Direct expansion inverter type or Chilled water system for complete cooling system flexibility. a Modulating Air flow thanks to EC high efficiency fans. The fans adapt to the thermal load detected by sensors positioned in the hot and cold aisle. This increases efficiency and reduces air stratification. a Perfectly compatible with most racks and ready for extension of the cooling system.

12 density zone < 5 /rack Data centers are specifically designed to create hot and cold aisles. Cold air is delivered through the floor or ducts exactly where it is needed and hot air returns to the HPAC units, thus improving the set point and the overall energy efficiency of the system. This system allows: a High efficiency a Perfect redundancy a Quick and easy expansion a Low initial investment The hot and cold aisle solution overcomes the limits of a traditional approach where cooling aims to maintain stable room conditions, forgetting to focus on the racks requirements. Cold Aisle 32,2 C Rack 26,7 C Rack Cold Aisle Rack Rack Cold Aisle 21,1 C 15,6 C 10 C In the last decade the data center design has dramatically changed. Years ago data center design was not driven by heat loads, so server distribution in the room was driven by other needs leading to only one reference room temperature. This used to be from 18 C to 24 C and it was an accepted standard throughout the world. As soon as server heat generation increased, it became clear a more rational distribution of heat was necessary; this resulted in the Hot & Cold Aisle concept. The arrangement of rack servers according to this logic allows delivery of cold air-flow exactly where it is needed - i.e. typically in front of the racks, greatly reducing the chances of cold and hot air mixing. This system increases the efficiency of the cooling system by 20% if compared to traditional layouts. On the other hand, this new concept requires two levels of temperatures to be properly defined.the optimisation of these temperatures leads to greatly improved working conditions. 12 l 13

13 Constant air flow and pressure management systems At the same time, the use of a raised floor has demostrated the clear advantage of distributing air where needed with negligible energy consumption. Those who designed very high raised floors could ensure extended life of their fast changing data centers. But such growth includes an increase of racks, data and power cabling and other ancillary services that almost completely fill the raised floor void, resulting in unexpected effects in air distribution. The best way, and sometimes the only way, to cope with this is to keep constant pressure in the floor void; this is fundamental to keep the required air distribution. What appeared to be a complicated problem to solve is now removed by the new Climaveneta pressure system. All HPAC units can be connected to several pressure sensors and the air control system automatically manages airflows in order to keep steady ambient conditions for the servers. The feature can be customised as Constant Air Pressure or Constant Air-Flow.

14 density zone /rack Aisle containment When hot and cold aisles are not enough to prevent air mixing, Aisle Containment ensures a perfect and homogeneous airflow to the server inlet. This system allows: a significant improvement in efficiency a tight control of conditioned air feeding the servers a the addition of more servers in less volume 32,2 C 26,7 C 21,1 C 15,6 C 10 C No aisle containment With aisle containment Aisle containment In medium/high density applications the presence of hot and cold aisles is not enough to prevent the mix of supply and return air. This mix results in air flow with a temperature that reduces the performance of the data center. If such air goes to the servers and it is warmer than expected the servers may stop working due to overheating. If mixed air goes to the cooling system and it is cooler than air coming out from the servers, heat exchange is reduced and then global efficiency is affected. Therefore it is necessary to provide a physical separation for the two airflows.this is achieved by using aisle containment, which is a simple and cost effective solution: it guarantees the servers are fed with the cold air and the cooling system is more efficient. The image above shows an excellent example of the advantages in terms of hot and cold flow separation obtained through aisle containment. 14 l 15

15 Cold Aisle configuration CRAC Roof Panel Baffle Floor Brush Seals 1 Climaveneta Aisle Containment The decision regarding usage of aisle containment needs to be analyzed on a project basis as it is affected by different factors such as: room dimensions, shape, heat load and density, cooling technology, redundancy provisions and more. In practice Climaveneta provides two methods for aisle containment: 1 Cold Aisle Containment, which provides tight control to the cold air feeding the servers. 2 Hot Aisle Containment, which confines hot discharge air from servers to one zone. Hot Aisle configuration CRAC Return Air Plenum Baffle Floor Brush Seals 2 Both the Hot and Cold Aisle Containment Systems provided by Climaveneta represent the perfect solution to: a Increase energy efficiency thanks to a complete separation of hot and cold air streams a Easily expand your data center if required by the layout of the environment a Perfectly integrate with different cooling technologies: - Inverter - In row units/ Enclosure units - Cooling door units a Optimise the available space a Adapt easily with or without raised floor design

16 density zone > 25 /rack This solution must accomodate the most critical heat load densities. Here hot-spots cannot be avoided without Climaveneta's localised air conditioners which are the best answer for dealing with hot spot management, providing extra local cooling exactly where it is needed. This system allows: a Maximisation of the internal capacity of the infrastructure a Elimination of hot spots a Minimum floorspace occupancy Climaveneta solution: CCD Cooling Door + CRC Rack Cooler CCD Climaveneta Cooling Door C C C a Additional cooling capacity thanks to chilled water coil available in both single & double circuit a Zero footprint a Adaptable for almost all racks a Top energy efficiency with electronically controlled fans modulated to actual needs a Dynamic air stratification management Tight control of the rack temperatures thanks to 8 independent sensors a Flexible connections From the top and from the bottom depending on the customer's choice and on raised floor availability a Ready to operate with latest generation chillers featuring magnetic levitation and free-cooling technologies. 16 l 17

30 Key Features The most efficient and reliable solution for high precision high conditioning is

31 From Climaveneta s experience i-accurate high precision air conditioners, available both as direct expansion and free-cooling versions are the most efficient and reliable solution on the market. Precise temperature and humidity control Complex IT centres require to keep temperature and humidity within very strict parameters. This is particularly difficult due to extremely variable thermal loads, that require very high cooling capacity at full load, in order to avoid to compromise the correct operation of the IT machines when they are more necessary. The massive use of the new INVERTER technology on HPAC units for technical rooms, makes possible to keep ambient temperature and humidity constant even with very strong loads variations, preventing dangerous temperature variations, almost unavoidable with traditional ON/OFF compressor driven units. High efficiency at partial loads Cooling IT load Data Center energy consumption Most energy consumed by modern data centres is due to ambient cooling. In more and more cases the cost due to cooling are higher than those caused by data exchange. In systems characterized by H24 operations, also the slightest compromise concerning efficiency has dramatic implications in the operating costs of the whole data centre. Hence it is crucial that the air conditioning system of the centre works effectively also at part loads, which are the most frequent operating condition, in order to reduce the overall operating cost. i-accurate strong point is exactly efficiency at part loads. Thanks to the adoption of inverter DC brushless compressors up to 30 and inverter AC for lager capacities, these units can reduce by 50% consumptions at part load, if compared to a traditional ON/OFF compressor. This is made possible also thanks to the advantages of variable air flow enabled by last generation EC fans. Versatility The many types of structures used as technical areas and the need to optimize their dimensions, require flexible solutions, that can adapt to any room, always granting perfect control and highest efficiency. This means complete flexibility, both as concerns capacities (from 6 to 150 Inverter), as well as configuration and system with 5 different cooling solutions, including FREECOOLING with R410A.

32 Technological choices Efficiency, versatility and reliability. Inverter technology The INVERTER technology on the compressor modulates the power capacity according to the real requirements of the server. This enables to optimize the performance of the compressor at part load, increasing rapidly its efficiency. Annual power consumption 100% In case of low Hz Operation 55% Max 70% 30% The latest generation i-accurate adopts this technology as standard in all its models, with several benefits in terms of: Modulation of the power capacity according to the load requirements No in-rush starting current Energy savings up to 50% compared to the traditional on/off technology. Constant speed AC Inverter DC Inverter Intelligent Control i-accurate, has an intelligent regulation, that allows the complete control of all the unit s parameters in any condition. i-accurate control is completely open and can be set according to the specific needs of the customer, either on site or in advance when the unit is produced. 2
