Beck Eva of Hewlett-Packard presented on the first day, the container data center "pod, HP." Containers are currently being intensively discussed in the market - including at this meeting. The biggest advantage in a container data center is, according to Beck, in the rapid deployment within just a few weeks and the high efficiency in terms of cooling owing to the small space. Dr. Bela Waldhauser, Global Switch FM GmbH, then presented the "ideal for building a data center from the perspective of an operator" and began by stating that there was no ideal way. Decisions to be made for the ideal building Dr. Waldhauser explained by subdividing into four categories: environment, if existing, the building itself, power / cooling and ultimately safety. The third and final lecture dealt with the issue of climate control. Achim Pfleiderer from the air conditioning experts Stulz GmbH began with a brief introduction to the technology and specifically defined the "precision air conditioning systems". He then explained the various "set screws" on the optimisation of air conditioning within a data center. Powered by Hackadelic Sliding Notes 1.6.5

Patrick Pulvermüller gave his lecture beginning with a qualitative insight into results of the study "German efficiency of data centers." As part of the survey, a total of 47 data centers within Germany were recorded in the period from March to August 2008. What was surprising, but positive, about the survey was that the efficiency (PUE = Power Usage Efficiency) by international standards was reported as very good. The average PUE of all collected data centers was 1.67. On a more negative note, however, it was noticed that the many simple ways to improve efficiency (e.g.blanking panels in the empty spaces in a rack) are used by only 55% of all respondents. The effects of these actions was quantified by simulations of the participants. Also completed, were opportunities for the cold aisle containment, discussed in existing data centers. The second lecture by Dr. Béla Waldhauser, Global Switch FM GmbH, focused on another working group within the Working Group Data Center that specifically handles the review of the DCSA. The aim is to divide the data centers in the future according to their purpose (e.g. co-location, hosting, personal use). The different types of benefits (such as air conditioning, building and mechanical safety, work processes, etc...) can be finally weighted differently depending on the application. Also new is that the certification is to take place in five steps. In the last presentation  Dr. Dieter Schramm, DELL GmbH dealt with the future of data centers from the perspective of the company Dell Computer. According to various studies, currently around 70% of the IT budget in the care and maintenance of data centers will be invested. At this point, Dell would begin with its concept of "Simplify IT" and reduce that number significantly. Other studies also showed that over 80% of all data center managers with the need for space and performance is a problem and don't know how to resolve it. Finally, Dr. Schramm pointed to a study from Switzerland, which considers the current cost in relation to air velocity. The study found that an air velocity of 2m / s is preferred. The next meetings are under the theme "Data Center 2015" and should give a look to the future of data centers, so that the managers are allowed to make the right decision for the renewal of their data center. A renewal of the data centers for almost 80% of all operators. Powered by Hackadelic Sliding Notes 1.6.5

Especially for large customers, like many data centers, it offers the opportunity to separate the rent for the network infrastructure and the cost of the electricity managed by the representative of the DB Netz AG. When it is then detached the power supply could then be saved even more by stream packets acquired at different times on the exchange. Owing to the diversified procurement into small packages it can then be obtained at a usually lower average price than the initial purchase of its requirements. Karl-Heinz Steffens of the E-TEC POWER MANAGEMENT GmbH , explicitly presented the advantages and disadvantages of the technology and gave an overview of the expected cost when using different UPS systems. Here, enormous savings depending on the technology used were clearly evident. Working group leader Patrick Pulvermüller then held the last of the working group introduced the questionnaire created to survey the efficiency of data centers "in Germany". The results of the questionnaire provide each participant the opportunity to compare their performance with the averages and then take the necessary steps. The eco invites all interested parties to participate in this very interesting benchmarking process. eco members are given a detailed analysis of the results available, which also provides the opportunity for deeper analysis. Finally, Oliver Thorner, eco Authorised Auditor and Senior Consultant of Alegri International GmbH , reported on the upcoming changes in the Datacenter Star audits. Here there was further need for discussion, in which the working group decided to also introduce a working group that deals with the development of audit metrics. A first working group meeting is planned for March / April. Powered by Hackadelic Sliding Notes 1.6.5
