Emerson the blackouts caused the most serious blackouts.
For example, power outages at delta air lines' data center caused $150 million in losses for the airline, and a power outage at the U.S. super bowl embarrassed organizers.
And a power outage could affect anyone at any time.

However, the difficulty faced by data center operators is to determine the root cause of the power outage, because the power outage is more complicated, for example, the server load is too heavy, causing the system to collapse.
The supply problem of local power suppliers, the human factors of the workers' misoperation.
Here are five of the most important issues that data center operators should focus on to ensure that no data center outages occur.
(1) can you move with the rapid development of the power system?
At different stages of the data center, demand for electricity is also changing.
The addition of servers or switches can have a significant impact on demand for power.
Therefore, it is important to be able to analyze the demand of the data center for a period of time in order to make long-term prediction easier.
(2) is the power chain threatened?
More and more data centers are connected to the network, and in addition to the terminals and access points included in the racks, many channels can be a destructive way to sabotage online crime.
In addition, network violations do not even need to be carried out through wires and cables.
Cunning criminals may enter a data center and disrupt the internal electricity supply.
However, it is not only the harm caused by the external malicious staff, but also the behavior of the staff inside the data center.
Some knowledge and inexperienced staff make mistakes when interacting with interfaces, which can also cause incalculable harm.
In order to prevent this, operation and maintenance documentation and process control are critical.
Adopting more hardware is not the best option to prevent catastrophic blackouts, in fact, adding additional hardware may actually make the situation worse.
(2) what is the disaster recovery plan?
Did you document the document?
Without affecting the business environment of power test, is actually a virtual switch equipment, this will allow data center operators can cope with the worst, and implementation of service recovery.
Data center workers always assume that their power supply chain and power backup systems are foolproof, but what would happen if there was no fail-safe test?
Power failure simulation enables data center operators to find a lack of redundant facilities and find a single point of failure.
However, this requires documentation to be documented.
Therefore, data center operators establish a power failure testing mechanism and record their recovery process before a catastrophic power failure.
(4) can the operation be monitored in real time?
Data center operators must know which devices are in place and how much power is being used.
This tends to be difficult for data centers that constantly increase infrastructure, because it can have a huge impact on power capacity and power distribution.
Note that the only effective method for all moving parts is a single view.
This holistic view has the capability of real-time monitoring and alerts to enable data center operators to mitigate risks and make changes to avoid disasters.
(5) do you know everything about the interconnection equipment and system?
For data center operations, it is essential that the power chain be recorded together, from the power that enters the building, through UPS, PDU/provided to all the rack equipment.
This means that data center operations need to know which devices are related to power, and how the devices are dependent on each other.
This allows data center operations to understand the potential impact of some device failures or offline maintenance.
In addition, you should understand the state of each power chain device.
Power management can be achieved by using data center infrastructure management (DCIM).
DCIM enables data center operations to run data centers with the highest efficiency, while allowing all relevant personnel to improve the overall operation situation and identify vulnerabilities to keep the power chain safe.
The deployment of DCIM can also enable data center operations to fully understand their products, eliminating the communication island between IT and facilities by sharing real-time data and easy-to-understand graphs.
Because of the power outages in data centers, it is difficult to try to keep up with all the changes in infrastructure by using artificial methods and spreadsheets, which can lead to unforeseen risks.
Therefore, appropriate and feasible methods and measures must be taken to manage.
