Three major concerns of data center wiring

The builders of Data Centers (DCs) will focus more on servers, storage and other IT equipment, even for the builders concerned about infrastructure, power distribution, refrigeration will also become their focus, integrated wiring often become a supporting role, or even become a "crowd actor", the result is the data center of the "whole scene" Lack of vitality.

High return on investment in a large background

Market consultancy Canalys data show that the global data center infrastructure reached $26.2 billion trillion in the third quarter of 2011, a 2.7% increase from the previous quarter. Market analyst Gartner data show that 2011 Global Data center hardware expenditure reached 99 billion U.S. dollars, an increase of 12.7% per cent, 2012 is expected to reach 106.4 billion U.S. dollars.

These two figures show a strong growth in the data center market (although there are some data indicating a slowdown in the global data center market, but in the "BRICS" market, which is still growing rapidly, moving into active phase), The data Center Working group of the Information and Communication Professional Committee of China Engineering Construction Standards Association conducted two surveys on China's data center construction in 2010 ~2011. From the statistical results, the data center room area showed a significant growth momentum, the Chinese data center market investment ratio is also increasing. Based on the analysis of the data Center construction Investment analysis in the next five years, the data center is generally growing in the construction investment in the next few years, and the basic annual growth rate is about 5%~10%.

In the face of fast-growing data centers, Internet data centers and cloud computing have become the most active hotspots in the world today. High-speed Ethernet, energy-saving, cloud computing and virtualization have become the main actors in the IT industry. In particular, cloud computing has been given a "third IT industry wave", more doomed to its strong vitality.

Cloud computing is based on data centers. The construction of data center will lead to the development of key it equipments, such as server, network, storage and so on, the physical support (such as power distribution, refrigeration, cabinet, fire fighting, wiring, monitoring, etc.) which is needed for the safe operation of these key it equipments becomes the key physical infrastructure of data center. Among them, power distribution and refrigeration are most concerned by builders, on the one hand, the distribution system for the data Center for all equipment to provide power support, reasonable distribution system design and implementation of the data center is the basis for safe and reliable operation, air-conditioning system for direct and data center heat dissipation, airflow organization related to energy-saving problems, so more and more become On the other hand, from the investment, power distribution and refrigeration will occupy the data center key physical infrastructure of the majority of the integrated wiring in the data center of the overall investment budget accounted for less than 5% of the wiring system is virtually ignored by the data center builders. But compared to other devices that we are more familiar with, such as servers, switches and active devices, integrated wiring provides the highest return on investment (ROI), the integrated wiring in its life cycle (10-15 years) to support at least 2~3 generation of network switching equipment upgrades, 3~5 PC hardware upgrades. Moreover, as an important part of the physical infrastructure of data center, the integrated cabling plays an irreplaceable role in the reliable operation of the data center.

Data center Cabling three key words

Small investment, big return. The value and significance of the data center wiring system can be described basically. So, which cabling technology will be accompanied by the construction of data center to achieve rapid development? million Gigabit copper, intelligent management, high-density become three key keywords.

High growth of Wan Xiaotong cable

Data center users in the selection of cabling system, the current 6 types of systems are still mainstream. However, we can not ignore the development of the million-gigabit copper cable system so far, the popularity of the increasing year. Especially in the 40g/100g era (the standard was released in June 2010, the technology has matured), we have no reason not to believe the arrival of the Wan Xiaotong cable era.

In fact, cabling system, as an information and communication infrastructure, should take into account the development law of the network in line with Moore's law. For the data center, from domestic and foreign standards (Ansi/tia 942, EN 50173-5, ISO/IEC 24764, GB 50174-2008) are required to meet the million-gigabit network bandwidth needs of the 6-type and million-gigabit copper cabling system, and EN 50173-5, iso/ IEC 24764 stipulates 6-A wiring system, so the use of million-gigabit copper cable will increase rapidly.

Of course, we can not deny that, in the mega-copper cable for the development of the same time, "light into the copper back" in the fiber will also get the ideal growth. And, due to the expansion of the engine room area to increase the unit room area and the function area increased, the backbone subsystem cable transmission distance, in the cable under the 100-meter length limit, the fiber will inevitably increase in the use of the volume. At present, the main factors restricting the development of mega copper cable are cost and actual demand (network transmission is not real traffic and the network products are not many), but these two constraints will gradually be eased. Need to explain, Wan Shao shielding system than unshielded system will get more applications, in addition to performance reasons, for technical reasons, the same brand of shielding system than the cost of shielding systems, this and 5 categories, 6 types of cabling system is just the opposite.
