The world's most important base metals exchange - London Metal Exchange (LME) issued a statement：On the evening of January 10, 2022 local time, a power outage in a third-party data center caused network connection problems, and trading resumed after a five-hour suspension.

Regarding the power outage, Eric Liu, trading director of Shanghai ASK Resources Co., Ltd. ''We were notified by the broker that the LME was unable to open trading due to connectivity issues with third party data centres，This will directly affect arbitrage trading, especially when other exchanges are still operating. But we have no choice but to wait for resolution''

Among all the failure factors in the data center, the power supply system has the greatest influence。No matter how sophisticated the IT equipment of the data center, how superior the system functions, and how high the reliability is, once the power is cut off, no matter how good the system is, it will not work.

How to ensure the power of the data center more securely?

First of all, the power demand of data centers is also changing at different stages of development. As a result, utility companies need to be able to analyze the demand for electricity in a data center over time to make long-term forecasts easier.

In order to meet the high availability of the data center, the reliability of the power supply is very important for the data center. Key core data centers require dual-circuit power supply, which is inseparable from the strong power supply support of the power grid，In the data center, it is generally necessary to configure the UPS uninterruptible power supply system. This kind of power supply equipment will not be interrupted due to short-term power outage, and the battery is an important part of the UPS. As the final guarantee for power supply, it is undoubtedly the last insurance of the UPS power supply。According to the survey, more than 70% of the data center accidents caused by the failure of the UPS power supply to supply power are caused by the battery failure，The battery is a link with a high accident rate of UPS power supply, which shows the necessity and urgency of improving the safe and reliable operation of the battery.

In order to solve the above problems, it is necessary to install a battery online monitoring system for the existing battery pack to monitor the voltage, internal resistance, pole temperature, current and other important parameters of the single battery online. Once a parameter is found to be abnormal, it will immediately alarm , so that it can be dealt with in time, which can prompt the maintainer to find problems or potential hidden dangers in time, and ensure the reliability and safety of the backup power supply of the data center.

Prevention is better than disaster relief. It is more effective to discover the hidden dangers of batteries as soon as possible, and eliminate the power outage disaster before it occurs, than to formulate an emergency plan！
