Accuray precision power distribution monitoring applications in data centers

0 Introduction Global web traffic has surged
under the pandemic, driven by the growth of digital applications such as video traffic, conference calls, and social networking.
As the Internet of Things continues to develop, the demand for data services will grow
exponentially in the future.
In addition, as a new engine of the economy, the digital economy has become an important indicator
to measure the comprehensive national strength of the country.
Therefore, it is necessary to accelerate the construction of a national integrated big data center system, strengthen the overall planning and intelligent scheduling of computing power, and build a number of national hub nodes and big data center clusters
.
1.
Industry policy In 2020, data center construction was officially included in the new infrastructure strategy
by the central government.
In recent years, the state has paid more and more attention, and the data center is the basic guarantee for the orderly operation of the new infrastructure and is regarded as the "infrastructure of the new infrastructure"
.
In February this year, the National Development and Reform Commission, together with the Cyberspace Administration of China, the Ministry of Industry and Information Technology, and the National Energy Administration, approved the construction of national hub nodes in four nodes, including Inner Mongolia, Guizhou, Gansu and Ningxia, and is working with relevant departments to thoroughly discuss the construction plans
of four nodes, including Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area and Chengdu-Chongqing.
Establish a high-speed data center direct connection network between clusters, implement the "East Data and Western Computing" project, support large-scale computing power scheduling, and build a new data flow-oriented computing power network pattern
。 2, data center users troubled data center is a gathering of a large number of servers, storage equipment, network equipment and supporting UPS, precision air conditioning and other equipment IT equipment place, is to achieve data information centralized processing, storage, transmission, exchange and centralized management of business and other business service platform, in recent years, domestic business processing of various industries dependence on information technology is increasing, the domestic data center market is gradually expanding, the scale of investment is growing rapidly, the demand for electricity is also increasing year by year, Data centers mainly face the following problems: 1) Due to the development of IT technology, especially virtualization and cloud computing, it is required to carry out comprehensive real-time management of the current distribution and power distribution of the entire data center to ensure the efficient and reliable operation of the power supply system and data center, and to achieve the dual purpose
of high reliability and energy saving and emission reduction of the data center.
2) Precision power distribution units provide power to IT loads, and the manufacturing technology of IT equipment is undergoing rapid development and change
.
The IT equipment and load power in the data center will change greatly in the next 10 years, but the service life of the data center and its power distribution system is generally 10 years or more
.
3) Due to the development of virtualization and cloud computing technologies, the power consumption of data centers will also become unpredictable
.
In summary, the data center is mainly reflected in how to continuously meet the changing IT load types and load operation levels throughout the life cycle of the data center, so that the entire data center can always maintain efficient and reliable operation in the process from completion to launch, which is a new challenge
for the power distribution system of the data center 。 3.
Accuray solution In view of the continuous change and rapid development of the IT load of the precision power distribution cabinet in the data center, it has also increased the requirements for the monitoring device in the precision power distribution cabinet, and a set of monitoring devices that can integrate various parameter measurement and monitoring and can fully meet the increasing load requirements has become an important indicator
in the modern precision power distribution cabinet.
Accuray AMC precision power distribution monitoring system can comprehensively manage the current distribution and power distribution of the entire data center in real time, and can realize up to 4 incoming lines, 192 outlets, electrical parameters, inlet and outlet switch status, temperature, leakage current and other comprehensive monitoring
.
And according to user needs, the number of
outlet measurement loops can be flexibly increased and reduced.
AMC precision power distribution system adopts multi-loop monitoring device, which can not only measure the three-phase current, voltage, active power, reactive power, apparent power, power factor, and frequency on the incoming side, but also detect the current, active power, power factor, and power data of the line at the same time
.
In this way, the electrical parameters of the entire distribution unit are effectively monitored and recorded in real time, especially with a real-time understanding
of its power consumption.
AMC precision power distribution monitoring system supports RS485 and TCP/IP protocol data transmission
.

Touch screen display interface AMC precision power management system main interface AMC precision power management system main way in interface AMC precision power management system main way outlet interface 5, conclusion Our company launched the precision distribution column head cabinet, for the data center computer room energy terminal, comprehensive collection of all energy data
。 Provide high-precision measurement data for the terminal energy monitoring system, reflect the power quality data in real time through the display unit, and upload the data to the background environmental monitoring system through RS485 communication, so as to achieve real-time monitoring and operation quality management of the entire power distribution system, and meet the needs
of most data centers.
