Data center specific power consumption optimizes: Data center specific power consumption optimizes PUE to drop technical method and practice
As the flying development of IT, data center already became the important infrastructure that props up modern society to move. However, the high-energy cost issue of data center also is highlighted increasingly, become the bottleneck that restricts its to be able to develop continuously. The article will be optimized around data center specific power consumption, discuss reduce PUE (Power Usage Effectiveness, the sources of energy uses efficiency) technical method and practice.
One, PUE and its importance
PUE is the main index that measures data center the sources of energy to use efficiency, its computation formula is: Total specific power consumption of center of PUE = data / IT equipment specific power consumption. PUE cost is lower, the sources of energy that shows data center uses efficiency taller. Reduce PUE, can reduce operation cost not only, return the effect that can reduce pair of environments.
2, data center specific power consumption optimizes technical method
1.Data center infrastructure is optimized
(1) optimize data center distribution: Layout of center of sound program data, raise dimensional utilization rate, reduce specific power consumption.
(2) use efficient refrigeration system: Choose efficient refrigeration equipment, reduce refrigeration system specific power consumption.
(3) optimize power system: Use device of efficient transformer, distribution, reduce power loss.
2.IT equipment is optimized
(1) choose efficient server: Choose can the server with effect tall comparing, reduce IT equipment specific power consumption.
(2) fictitious change a technology: Through fictitious change a technology, raise server utilization rate, reduce specific power consumption.
(3) optimize storage system: Use the storage device of efficient, low power comsumption, reduce storage system specific power consumption.
3.Data center carries dimension management is optimized
(1) real time monitoring: Use advanced monitoring technology, real time monitors situation of data center specific power consumption, seasonable discovery is unusual.
(2) energy-saving strategy: Formulate sound energy-saving strategy, if adjust equipment moving parameter, optimize equipment run time to wait.
(3) Training Within Industry: Strengthen dimension of data center carry Training Within Industry, raise energy-saving consciousness.
3, carry out case
1.Case one: Some large data center is passed optimize refrigeration system, reduced PUE 0.2.
Concrete step: Change efficient refrigeration equipment, optimize refrigeration system distribution, use energy-saving and cooling technology to wait.
2.Case 2: Some enterprise is passed fictitious change a technology, reduced PUE 0.1.
Concrete step: Undertake to the server fictitious change, raise server utilization rate; Optimize fictitious change platform, reduce specific power consumption.
4, summary
Data center specific power consumption is optimized is the key that reduces PUE. Through optimizing equipment of data center infrastructure, IT and carry dimension management, can reduce data center specific power consumption effectively, raise the sources of energy to use efficiency. In carrying out a process, enterprise should according to oneself actual condition, choose right technical way, specific power consumption of implementation data center is optimized.
Anyhow, data center specific power consumption is optimized is project of a system, need from many respects proceed with, improve continuously. As ceaseless development of the technology, data center specific power consumption is optimized will more and more be taken seriously, to can last of industry of center of our country data development lays a foundation.
