【 Weak current College 】 on data center infrastructure availability issues

In pursuit of high availability of enterprise IT management and services, only in computer hardware and software platform investments is not enough, you also need corresponding matching and complementary infrastructure such as power supply, air conditioning, as well as other related environmental support system, so you can reach IT to the data center high availability goals.

To improve data center construction, operation and maintenance of risk management, data center security, reliable and stable operation, data center availability, nature, reliability, scalability, manageability, data center infrastructure, high availability, you need to meet the following conditions: a highly available data center location to meet the computing station GB9361-88 site safety requirements in A class room location; for data center facilities design and construction to meet the specifications for the design of electronic computer room — GB50174-2008 People's Republic of China and the national standards GB/T2887-2000 electronic computer site Universal standardized Specificationforelectroniccomputerfield law;

As a green, high-availability data center, project planning, preliminary design phase, project construction stage as well as project acceptance phase, should take full account of the data centre building infrastructure, electrical systems, cabling, monitor, monitoring, and other requirements, and deliberating demonstration, learning from international and domestic movement of construction and management experience, to form the final construction programme, and to advance the scientific management mode project construction work.

Infrastructure in the high availability of significance

As the IT information system has been constantly expanding scale is continually expanding, and large-scale natural disasters, man-made disasters and emergencies are occurring, resulting in the accumulation of risk information system, the national regulatory authorityto supervise and inspect the intensity.

To reduce information technology, risk of business disruption, effective management of the risk of damage to infrastructure, in particular, should improve its usability, data center from an unpredictable, low efficiency of state transitions to sustainable development, efficient State, greatly reduced, improving data center operational costs and IT budget.

Data Center construction can be broadly divided into two conditions for implementation, a new data center design, another existing data center extension. For both cases, the design of architectural design, power supply, air conditioning system design, comprehensive wiring design, security and appropriate lighting system is designed to be elementary. But for high availability, infrastructure, building structures, electrical systems, HVAC systems, cabling and are the focus of the following is how to implement data center infrastructure high availability measures do some explaining.

Infrastructure highly available technical measures

1. construction structural

As a host of important information system of the data center, the venue location, you need to consider the following aspects, in General, including: regional urban development focus: Data Center for power supply, communication facilities and municipal equipment requirements, will get a higher security efforts; on the other hand, General requirements for the data center is as close as possible to permanent roads, have better conditions to facilitate resolution of the municipal water supply, power supply, communication lines.

In the data centre building aspects to consider: data center room main architectural appearance neat, compact size, minimize the exterior wall area.; enhanced building envelope insulation performance and heat insulation performance; host room and uninterruptible power system room design live load to achieve 8 ~ 10KN/M2, the battery compartment live load to achieve 16KN/M2, host room fire resistance ratings should not be less than the second.

2. electrical system

For electrical system, the external power supply meet, data center design to scheduled during the life cycle of a data center with demand and achieve on-demand.

In the power supply and distribution system, a set of reliable, good computer power supply and distribution system is the guarantee of computer equipment, ground equipment and auxiliary electrical equipment safety run prerequisite. In order to guarantee the quality of supply of computer equipment, computer lab site requires independent power distribution system, dual-source changeover system, plus UPS power systems, comprising reached level load standard for many uses large servers and other equipment, you need to achieve reliable grounding.

Through battery configuration, optimizing the UPS system reliability. Power failure in the external power supply, energy-saving and environment-friendly generator uses the automatic or manual and network capability, bus segment continue to load a constant, stable provided electricity to improve data center power supply system for high availability.

3. air conditioning system

Data center energy consumption of air conditioning systems to data center energy consumption of 45%, to optimize the entire air-conditioning system, can significantly increase the service life of the device, increasing the availability of air conditioning systems.

First, large data center air-conditioning system currently uses itself with microcomputer control for chillers for fully automatic operation. And the use of automatic control level higher refrigeration units, optionally automatically adjust the cooling capacity; equipment reliability improvement, enhanced air conditioning system for high availability.

Once again, through rational planning provide redundant n + x, avoiding single points of failure on air conditioning system high availability impact.

Finally, in the operation and maintenance of effective conservation and equipment spare parts management, improve its high availability.

4. integrated wiring

From the layout, the rooms have three points to note: first, the space savings; the second is to improve the effective management of wires and air convection channel; the third is the reliability of the equipment operation.

Foundation network construction with advancedSex, forward-looking, meet now 5 years, 8 years of demand, even 10 years, 15 years later.

Cable management wiring density and cable in the computer room cooling effect, if the cable confusing active cooling is very difficult to compare; if cable, smoothly some savings in energy consumption of refrigerating equipment. Computer room cabling there are many things in it, including rational reason rational reason wire line, to prevent confusion caused cooling channel plug wires, you can increase the cooling efficiency.

The green room and high-availability infrastructure

About the Datacenter High availability must include green room concept. Green Room concept should include energy-saving and environmental protection in two parts, one energy-saving is not merely conserve power, should also include savings. This savings is multifaceted, including energy conservation, saving refrigeration equipment costs and device backup and redundancy, which should also include a computer room space savings and all resource savings. Therefore, data center infrastructure required to meet the requirements of energy-saving and environmental protection, resource utilization, increase integration of equipment usage, improve the reliability of the device used to improve the infrastructure for high availability.

Following adoption of industry experts, service providers and extensive practice experience, infrastructure, green development direction did some finishing, as follows:

1. close to the heat source of refrigeration: this schema can be greatly reduced heat and heat systems, ensure that the location of the generated heat for adequate cooling.

2. air conditioning mounted under the engine cooling fan: corridor air supply mode is more and more people are recognized and accepted, and in the actual room layout to be fully exploited. In response, a home-based on "next" idea, passed the blower fan following reset can significantly reduce the air path on the damage caused by cold, and for daily maintenance of the device also provides convenient.

3. the application of rational planning of components: the growth of the "edge" principle for investment is modular and extensible framework, based on actual need on certain devices or region-specific power supply and cooling. Reasonable planning framework without having to pay for idle equipment more high additional costs.

4. take full advantage of the natural climate region: If outdoor air temperature falls below the set temperature point, through the control regulation damper on the outdoor air filtered into the cooling system.

5. regular monitoring and adjustment: through constant testing and adjusting the environment to enable the engine room environment optimal temperature and humidity.

6. avoid excessive cooling system: through continual testing can determine a system's reasonable estimate of the electric power load than the manufacturers estimate how much lower. Knowing this, companies will be able to monitor each rack power usage, appropriate adjustments to the cooling system, thereby reducing the cooling and the waste of energy.

7. continuous improvement of heat isolation: in order to isolate heat, enterprises can heat the ends of the channel and the rack cooling exhaust system surrounding the use of transparent plastic curtain, to make the piping and equipment, together with physical barriers around the form.

8. the use of waste heat by near the area where the electricity generation, to reduce power costs, and reduce the transmission of electricity in the process of loss; can also be directly from cogeneration.
