Journal Summary
p. 6. Just Work and It’s Going to be All Right
O. Ponomareva
In the middle of February we completed the DC Lady competition, and now we are pleased to announce the winner: Olga Ponomareva, General director of Inoventica Services. Olga is talking about her study in the Military Academy of Strategic Rocket Forces named after Peter the Great. She is also telling about her route into the data center industry, her work in the Inventica Group of Companies, her best project, as well as her hobbies and family.
p. 12. Combined Engineering Infrastructure Testing for a Data Center. A Non-Documented Theory Verified by Personal Experience.
I.Basin
The article talks about the integrated testing of engineering and technical systems of a data center, along with providing a clear definition and outlining the goals and objectives of such tests. The author outlines in detail the program and methodology of integrated testing, as well as choice of time, location and team for such testing, preparation, ownership of processes, task of each group involved, list of organizational issues, and the criteria of successful testing.
p. 19. Skills and Knowledge of the Professionals Contribute to the National Standards of Testing
D.Basistiy
The author reviews I.Basin’s article Combined Engineering Infrastructure Testing for a Data Center. A Non-Documented Theory Verified by Personal Experience. The author believes that the ideas of I.Basin’s article may serve as prototype for the new national standard for integrated testing of the engineering infrastructure of a data center and suggests a map for standardization of this scheme.
p. 20. Testing of the Power Supply System of a Data Center
S. Ermakov
The article covers approaches to both factory and warehouse testing of the data center power supply system, either based on the classical architecture including a static UPS and diesel generator, or on the dynamic architecture including a Dynamic Running UPS (DRUPS). The author describes the preparatory measures preceding the testing, and focuses on the methods of testing and normative documents regulating the testing procedures.
p. 24. Testing of Precision Air Conditioners: Stulz Testing Facility
S. Zelenkov
The Stulz testing center in Hamburg, a German manufacturer of air conditioning and cooling systems, serves as a testing site for both ready products and its prototypes during research. Testing is carried out in close-to-real conditions, allowing a high degree of accuracy in estimating the efficiency of all systems and components. The sealed testing zone serves for two types of tests: 1. Demonstration tests for all types of climate, and 2. Prototype tests - where the electrical and electronic components are tested in the course of their development.
p. 26. Testing DRUPS: Factory Testing at EURO-DIESEL
A. Zaitsev
EURO-DIESEL products are manufactured at the Liege facility in Belgium, where the world’s largest testing site is also situated. The design of the DRUPS allows shaft alignment to be performed only once during assembly at the factory, after which the system is then delivered to the customer and ready for use without any additional tuning. The article outlines the advantages of the key nodes of the DRUPS produced by EURO-DIESEL - notably battery and electromagnetic coupling. The article outlines a detailed overview of the assembly process and steps of testing of separate elements, as well as an overview of the entire system.
p. 28. What is the Right Way to Perform Heat Load Testing of a Data Center?
M. Filippov
The author provides practical recommendations about organizing the process of testing heat load of a new data center, including the testing stages, components, and sample list of optimal testing procedures. One will find information about specific situations one may face in the course of testing. Special focus is on the methodology and choice of emulating workload. The article is based on a profound experience the author has had in the testing domain.
p. 32. Testing: Poll
I. Dorofeev
The last, but not least, on this issue’s main topic of infrastructure testing: the magazine has carried out a poll among the audience about the necessity of tests, their duration, and cost. Igor Dorofeev, General Director of ICord, is commenting on the results.
p. 37. Data center: Preflight Preparation
G. Willner
Testing is the fundamental rule of a data center, revealing hidden faults before they make one’s life difficult. There are two stages of testing engineering infrastructure: 1. Component testing, and 2. Integrated System testing. In order to ensure that all systems function properly, one should emulate the full workload during the testing process.
p. 38. Russian Data Centers are to Receive National Standards
A.Degtyarev
Russian data centers mostly use foreign technologies. This is the reason why the market for the past decade has been guided by foreign standards and norms. Russia does not yet have a unified national standard for the industry, which would embrace the entire scope of matters including construction and operations of a datacenter. Alexey Degtyarev, the President of the Russian Association of the Data Center Industry, is talking about development of such national standard.
p. 41. Supercomputer Lomonosov: Speeding up the Computing Cycle
V. Gavrilov
When Lomonosov, the most powerful Russian high performance computer, was created, AMD Technologies was responsible for the most complex part of the project: the engineering infrastructure for the entire computing system. The two-circuit cooling configuration system, including dry-coolers, air plate-and-frame exchangers, distributing headers and water-pumps, is capable of removing a total of 10MW of heat from 128 racks. The design of the Lomonosov engineering infrastructure allows further scaling up to 54 Pflops.
p. 42. Commercial Data Centers of the Moscow Region: Overall Supply
V. Demchishin
In February 2015, Modern Telecommunications conducted research of the status and overall perspective of supply growth in the commercial data center sector in the Moscow metro area, and also updated the ratings of data centers. The article contains information on the current overall supply as of early 2015 represented in sqm and racks, the rating of the leading operators, as well as a cautious forecast of the dynamics of supply in terms of potential new space located in commercial data centers yet to be introduced.
p.44. Data Centers and the Crisis: Time for New Opportunities
A. Platonov
While the economic crisis negatively affects the data center market along with other industries, it also opens up new opportunities such as the staffing and migration of customers from foreign into Russian data centers. Anton Platonov considers the challenges data centers are facing at the moment, the means of overcoming these challenges, and the future prospects for the industry.
p. 46. Seizure of Servers: What One Can Do?
A. Panov
Seizure of servers from a commercial data center is a common practice of the Russian law enforcement authorities, and these actions are governed by the law on operational and investigative activity. The problem is that one physical server often hosts data and applications of many clients, not just one, and the owner may not see his server for six months or more. The author considers the means of resolving this dilemma based on the practice existing in other countries and articulates potential ways of improving the Russian laws.
p. 50. Does One Need to be a Member of a Self-Regulating Organization to Perform Maintenance of Data Center Infrastructure?
A. Danilochkina
The data center construction process poses certain legal questions: in light of uncertainty of the status of the data center and grey areas in the law, one may find it hard to demarcate the domain of strict application of normative acts from other situations where one can enjoy more freedom. An example of one such grey area is the requirement for a contractor to be a member of a self-regulating organization. The question of a reader receives comments from a lawyer.
p. 54. Where has the Data Center Gone?
A. Panov
The managing team of RBC, without letting the shareholders know, dismantled the infrastructure of the JSC Bite Telecom data center and moved the servers to a new site. Alexander Panov, former managing director of Hosting Community (which was the major tenant of that facility), tells how one can wake up on one sunny day and find out that he no longer owns anything.
