Data center Introduction

 

Data centers are one of the indispensable infrastructures in modern society. They carry various key businesses and applications, such as cloud computing, big data, and artificial intelligence. However, the energy consumption of data centers is very high. It is estimated that the energy consumption of global data centers accounts for about 2% of the world’s total energy consumption. In order to deal with this problem, data centers need to take comprehensive energy efficiency management measures to reduce energy consumption, improve resource utilization, and reduce operating costs. Acrel comprehensive energy efficiency management solution for data centers is born for this purpose. It combines multiple technical means such as physical equipment management, environmental monitoring, energy management, and intelligent optimization to help data centers achieve reliable and sustainable operations.
