Computer room PUE optimizes plan: Promotion of power supply efficiency and loss are reduced
In current informatization times, data center serves as the crucial infrastructure that supports of all kinds professional work, its the sources of energy is used up be paid close attention to with environmental protection problem increasingly. PUE (Power Usage Effectiveness, the sources of energy uses efficiency) as the main index that measures efficiency of data center energy, had made the central point that industry pays close attention to. The article will optimize plan to spread out development to discuss around computer room PUE, aim to promote power supply efficiency, reduce loss, to can last of industry of center of our country data development contributes force.
One, the concept of PUE and importance
PUE is an index occupy central total specific power consumption and IT equipment specific power consumption than, its computation formula is:
Total specific power consumption of center of PUE = data / IT equipment specific power consumption
Below good case, the value of PUE is 1, mean all the sources of energy to be used at supporting IT equipment to move. However, in applying actually, because come loose the existence of the auxiliary equipment such as hot, illume, air conditioning, PUE often ambitious at 1. Accordingly, reduce PUE, raise the sources of energy to use efficiency, have important sense to data center.
2, computer room PUE optimizes plan
1.Improve efficiency of energy of computer room whole
(1) optimize air conditioning system: Use efficient and energy-saving air conditioning device, improve the refrigeration efficiency of air conditioning system; System of reasonable design air conditioning, implementation essence is accurate lukewarm accuse, avoid excessive refrigeration.
(2) optimize lighting system: Use the efficient and energy-saving illume device such as lamp of energy-saving bulb, LED, reduce the specific power consumption of lighting system.
(3) optimize power system: Use facilities of efficient and energy-saving transformer, distribution to wait, reduce the loss of power system.
2.Improve efficiency of IT facilities energy
(1) choose efficient and energy-saving IT equipment: In purchasing a process, first choice PUE is worth inferior IT equipment, wait like equipment of server, storage.
(2) optimize IT facilities distribution: The facilities distribution of sound program computer room, avoid equipment to be placed thick and fast bring about medicinal powder hot difficulty, raise equipment to come loose thermal efficiency.
(3) use fictitious change a technology: Through fictitious change a technology, reduce the amount of physical server, reduce specific power consumption.
3.Strengthen energy management
(1) real time monitors: Use specific power consumption to monitor a system, real time monitors data center data of each specific power consumption, discover specific power consumption is unusual in time circumstance.
(2) data statistic analysis: Undertake to data of specific power consumption statistic is analysed, find out specific power consumption to be worth a dot high, make specific aim optimize measure.
(3) enact energy-saving measure: According to data of specific power consumption, enact relevant energy-saving measure, if adjust equipment run time, shut needless equipment to wait.
3, optimize plan to carry out the effect
Optimize plan through carrying out computer room PUE, can achieve the following result:
1.Reduce energy cost: Raise the sources of energy to use efficiency, reduce specific power consumption, reduce energy cost thereby.
2.Reduce carbon to discharge: Reduce data center specific power consumption, reduce carbon to discharge, be helpful for environmental protection.
3.Improve equipment life: Optimize equipment to run an environment, lower equipment fault rate, prolong equipment life.
4.Promote an enterprise competition ability: Reduce specific power consumption, raise the sources of energy to use efficiency, conduce to an enterprise showing itself in market competition.
Anyhow, computer room PUE optimizes plan to reduce a respect to have important sense in promotion of power supply efficiency and loss. The company should take relevant step actively, reduce data center specific power consumption, implementation can develop continuously.
