With the advent of the era of cloud computing and big data, data centers have become an indispensable and important part of modern society. As the core facility for data storage, processing and transmission, the data center computer room's stability and reliability are crucial to ensuring the normal operation of information technology systems. In the design and construction of data center computer rooms, sequential power-on technology is widely used to provide safer and more reliable power supply guarantee.
1. The meaning of timing power-on
Timing refers to the order in time. As the name suggests, timing power-on refers to the order in which the power supply time of each electrical device is arranged. In an IDC data center computer room, usually when the switching power supply is started, the main power grid at the input end may be required to provide a short-term large current pulse. This current pulse is usually called "inrush current" and will cause the input voltage to rise. The waveform collapses, which worsens the power supply quality and affects the work of other electrical equipment.
2. Application of sequential power-on PDU
In order to solve the above problems, a timing function is added to the PDU. When the front end of the PDU is powered on, its output holes corresponding to the server are not powered on immediately after the power is turned on, but are powered on in a delayed manner according to the preset sequence. The surge current peak is generated and the overall surge impact on the front end is reduced.
(1) Maintain the stability of the equipment: Since the voltage and current of the power grid change very frequently, a momentary voltage that is too high or too low may cause the equipment to fail. PDU with sequential power-on function can avoid voltage fluctuations to a certain extent. Excessive size may cause equipment failure. In addition, when the power facilities in the data center computer room fail, delayed power-on technology can ensure the stability of the equipment by waiting for the power facilities to operate normally before restarting the equipment.
(2) Reduce the overall energy consumption of the computer room: In the data center computer room, a large number of equipment need to be started and shut down continuously, which will generate a large amount of startup energy consumption. Through the sequential power-on function, the surge current when the equipment is started is reduced, thereby Reduce overall data center energy consumption.
(3) Efficiently reduce system vulnerabilities: Sequential power-on technology can realize unified scheduling and management of equipment through a centralized control system, flexibly configure the startup sequence and time intervals of equipment, and monitor the power demand and status of equipment in real time to reduce the occurrence of faults. efficiency, providing more convenience and flexibility for computer room operation and maintenance management.
3.TOWE sequential power-on smart PDU products
