Несмотря на все старания проектировщиков обеспечить дата-центры надежной системой защиты от сбоев и аварийных ситуаций, аварии все же случаются, причем их появлению может предшествовать целая цепочка событий. Это иногда приводит к сбою в самых надежных системах защиты от «неприятностей», и работа ДЦ прекращается.
В продолжении — несколько случаев, как давних, так и произошедших совсем недавно, которые показывают, что некоторые ситуации просто невозможно предусмотреть.
С ростом популярности продуктов корпорации Apple, включая как мобильные устройства, так и сервисы, нагрузка на дата-центры компании также постоянно увеличивается. Сейчас компания зависит от традиционных провайдеров и поставщиков оборудования в плане поддержки сервисов iTunes, iCloud, Siri и прочих. При этом корпорация планирует расширить свои дата-центры, увеличив их производительность, а также объединить эти объекты при помощи скоростной сети.
Основная задача при этом — создание продвинутой облачной инфраструктуры. Инвестировать в этот проект Apple собирается миллиарды долларов, при этом в прошлом году $1 миллиард был потрачен на расширение существующих и создание новых дата-центров. Какие промежуточные этапы предстоит выполнить в ходе реализации такого масштабного проекта?
The companies which are engaged in Bitcoin mining do not pay attention to falling of cost of unit of cryptocurrency in relation to dollar. Moreover, such companies continue to develop IT infrastructure, and some even plan creation of new data-centers.
So, the BitFury company, one of the largest mayner in the world, has bought ground in Georgia where it is going to construct huge data-center where the corresponding equipment will be placed. One more company, KnCMiner, one more heavyweight in the world of mining of bitcoins, has got ground in Sweden, with the similar purpose. Both companies make the equipment for cryptocurrency mining, and are going to construct own data-centers for the same purpose.
In Asia the number of Internet users continues to increase and to ensure normal functioning of the resources in this region, the Google corporation is going to expand local data-centers. The data-center in Singapore will most strongly undergo changes, will also expand DTs which is in Taiwan.
As for Singapore, the local data-center of Google has earned 18 months ago. Now add the second, multi-level DTs which will be located with row to the first object. The cost of such object will make $500 million. Earlier the corporation has already spent about $600 million so in Singapore it is invested $1 billion money of the search giant for this data-center.
Systems of submersible (immersion) cooling are known for a long time. Thus still distribution of similar systems and their implementation happens not too actively. Nevertheless, progress nevertheless is, some data-centers use systems of submersible cooling, and are not going to pass to former types of cooling systems.
In similar systems the coolant of the Novec company which is considered by the undoubted leader is usually used. But anything constant is not present, gradually there are alternative coolants. One of new, perspective projects is the passive cooling system on the basis of Fluorinert Electronic Liquid FC-72. This liquid does not carry out current plus is very stable (chemically and thermally). Here at once to tell that developers use the cooling system which does not demand immersion of all server in capacity with liquid. Authors of the project — the staff of University of Alabama, Hantsvill (University of Alabama in Huntsville).
Known for much on Habré the Uptime Institute organization the other day announced new system of assessment and certification of data-centers. The system has received the name Efficient IT Stamp of Approval. Representatives of the company have presented new development on the anniversary (tenth) Uptime Institute Symposium conference which took place in the city of Santa Clara, California, USA. Let's note that this system is two-level, and pacing factors which are used for DTs assessment, overall performance of infrastructure of object and influence of DTs on environment are.
The system of estimates is quite simple? now certification provides possibility of receiving two categories certificates. The first? Approved. This category of certification is appropriated to those objects which completely correspond to all criteria of assessment. Thus the certificate is issued for two years then it needs to be confirmed.
So-called cable management? difficult work which demands not only accuracy, but also accuracy. For work with cables, connection, marking, etc. is required a lot of time. Engineers of data-center are come to the rescue by the thermoseated materials which help to mark cables, and marking keeps very long time, and process of drawing labels becomes simpler.
In principle, marking of cables with use of the thermoseated materials? the idea not new, but now it is widely adopted. Some companies let out convenient hand tools for marking with use of such materials. Thus texts on labels markers turn out very accurate and resistant. The question of marking of cables is really important, for unification of this process special standards one of which (the voluntary standard created by ANSI institute) is ANSI/TIA 606-B are entered.
3 years, 3 months ago From far away all this seems small, but DTs Square? these are two football fields
Large telecommunication companies constantly expand the capacities as becomes more increasing than clients, and requirements at clients everything is higher. Is not exception and the known company Rackspace. At the end of the last month this company has started new data-center which is located in Great Britain, Crowley (about 50 km from London). In new data-center it is implemented many interesting technologies allowing to save resources and to work more effectively.
According to the manual of the company, this data-center is the largest in the country where the technology of indirect (indirect) cooling, with intake of fresh air is used. Thanks to this and some other technologies, the company could achieve PUE=1.15 at mean value of PUE for other data-centers in 1.7. New data-center? already the tenth for Rackspace, in Great Britain at this company now two data-centers.
Increasing number of telecommunication companies is passed to alternative energy sources. Someone does it under the influence of the public, still someone for diversification of the main sources of power supply. The Equinix company has decided to set in the data-center from the Silicon Valley fuel elements from Bloom Energy which work at biogas. The original project provides installation of station with a power of 1 MW in SV5 data-center. It is expected that fuel elements will be able to provide giving of 8,3 million KWh of energy a year.
Equinix now is going to pass completely to renewable energy resources, and makes considerable efforts for achievement of this purpose. Now DTs of the company receive about 30% of energy from alternative sources, including fuel elements, solar energy, etc. As for fuel elements, their advantage is work on biogas which is developed from organic residues. Now the main objective of power station from Bloom? to support work of power infrastructure of DTs at the constant level, for example, during problems in the main network.
The Amazon corporation has signed with the Siemens company the 13-year contract for creation of 150 MW of vetroenergostantion (wind farm) in the USA. Thus, the company continues implementation on transition to the energy received from renewable sources. Before Amazon has assumed the obligation for some years to pass providing to 100%? green energy?.
Vetroenergostantion has received the name Amazon Wind Farm (Fowler Ridge), and Benton, Indiana, the USA will accommodate in the district. Energy of station will be used for work of the local data-center ensuring functioning of Amazon Web Services. By the way, earlier the Amazon company has declared that in the data-center servicing Amazon Web Services the Tesla accumulator plants will be installed. In DTs Amazon will install accumulator system of Tesla in 4.8 mvt*ch. In April the company has joined the American council for renewable energy resources, and also announced participation in US PREF (U.S. Partnership for Renewable Energy Finance), for ensuring interaction with local government concerning use of renewable energy resources for cloudy providers.
