With the supporting of the new infrastructure policy, IDC, as one of the keys of novel form infrastructure construction to support the digital, networked and intelligent transformation of economy and society, has ushered in new opportunities for historical development. However, in the whole life span of IDC, the delivery of operation and maintenance is a stage with long time, complicated workflow and high-cost investment, and it is also an important stage to realize the value of IDC. Hotwon, as a professional leader of cloud computing base, pays special attention to data center operation and maintenance delivery management.

On July 24th Operation and Maintenance Day, Hotwon together with cloud computing bases in Hangzhou, Guangzhou, Chengdu, Foshan, Tianjin and Guiyang held the "large-scale joint drill of operation and maintenance in six places and three centers".

This drill mainly focuses on practical exercises and simulation of movements. In order to verify the reliability of automatic control logic of high and low voltage power distribution system in case of double-way mains power failure, the time required for diesel engine to automatically start and output to electric equipment, ensures the stability and safety of the running of power supply and distribution system equipment and heating and ventilation system in Hotwon data center, improves the emergency handling ability of Hotwon operation and maintenance team for single-way and double-way mains power failure, and prepares for emergency deployment by Hotwon operation and maintenance team. These six places were jointly launched with the emergency drill of diesel engine with load in case of two-way mains power failure, emergency drill of BA system downtime, emergency drill of PDU power failure, emergency drill of handling of server loss, drill of handling of detached and disconnection of network equipment, and drill of tail fiber inspection of network packet loss optical module.

Hangzhou station

-Hotwon emergency drill of diesel engine with load in case of two-way mains power failure-

After the dynamic environment system alarming, the electrical and heating and ventilation engineers immediately response, check the failures of field equipment, feedback the monitoring posts in the monitoring duty room, and troubleshooting the failures.

Hotwon Hangzhou high-performance cloud computing laboratory can verify the stability of automatic logic function of high-voltage and low-voltage power distribution system by implementing two-way emergency drill for mains power outage, develop the quick and organized emergency handling ability of operation and maintenance personnel, reduce unnecessary risk of human failure, and scientifically standardize emergency response behavior.

Guangzhou station

-Hotwon Emergency drill of BA system downtime of Hotwon-

The patrol personnel on duty check the equipment status, check whether the system equipment is running normally, troubleshooting the failure and ensure the normal operation of the equipment.

Training the personnel regularly, thus ensures the security. Hotwon Guangzhou No.1 cloud computing base will normalize the drills. With high-intensity and high-frequency emergency drills, operation and maintenance personnel can be familiar with the emergency procedures and familiar with the operations according to simulation and movement drills.

Chengdu station

-Hotwon Emergency drill of PDU power failure of Hotwon-

On-site temporary failure inspection, the inspection and repair are completed by engineers.

The cabinet lost power in one-way at Chengdu No.1 cloud computing base simulation data center. Hotwon operation and maintenance personnel responded quickly with temporary PDU to restore the cabinet two-way power supply, and then restored the on-site power supply after the failure was handled. Ensure that the spare parts of important equipment are sufficient. For the equipment problems that cause PDU power failure, the spare parts of important equipment in IDC are sufficient, which can handle failure events quickly.

Foshan station

-Hotwon emergency drill of handling of server loss-

Server failure inquiry, network recovery and normal access.

Hotwon professional operation and maintenance team is stationed on site to provide 7*24-hour operation and maintenance response. During the drill, the trouble reporting process is concise and fast, rapid in response, and professional in failure handling. After troubleshooting, analyze, standardize, register, summarize and archive the cause, process and result of the failure.

TianJin station

-Hotwon drill of handling of detached and disconnection of network equipment-

Troubleshooting the network equipment and organize optical fiber.

The network department reported that the network equipment is disconnection of network, and the operation and maintenance personnel first carried out physical checking. For the problem of detached and disconnection of network equipment, Hotwon operation and maintenance personnel handled it quickly and solved the problem faster. Perfected power, air conditioning, monitoring and other equipment can ensure the normal operation of the equipment.

Guiyang station

-Hotwon drill of tail fiber inspection of network packet loss optical module-

Locate the failure equipment and check the tail fiber of cabinet.

It was found that the tail fiber of IDC was transmitting light normally, and the optical module of the client failed. Hotwon stationed operation and maintenance quickly replaced the failed module, after tested by the customer, it returns to normal, the failure has been solved. During the whole process, the Hotwon operation and maintenance personnel were quick and professional, providing customers with security, reliable and professional operation and maintenance services, and ensuring the normal business of customers.

The drill is conducted in a multi-dimensional cooperative way, such as network layer and data transport layer, which effectively ensures the smooth network, data security and operation and maintenance of IDC. The drill strengthened the emergency handling ability of Hotwon operation and maintenance team for emergency failures, and tested the stability and safety of the running of power supply and distribution system equipment and heating and ventilation system in Hotwon data center, as well as the execution ability of on-site operation and maintenance personnel for on-site handling and the ability of on-site linkage and cooperation. In addition, the drill also invited customers made their personal appearance, and many customers appreciate the emergency handling ability and multi-dimensional coordination ability of Hotwon operation and maintenance personnel.

Through the unremitting and concerted efforts of Hotwon operation and maintenance personnel, this large-scale joint drill of operation and maintenance was a complete success, and only the accumulation of quantity can make a qualitative leap. The success of the drill shall owe to the accumulation of daily operation and maintenance. Despite of holding large-scale drill every year, Hotwon often conducts daily operation and maintenance drill. Hotwon strives to plan and improve the underlying construction from the perspective of data center value realization, so as to ensure the stable and long-term operation of IDC throughout its life span.

Today is Hotwon July 24th Operation and Maintenance Day, the operation and maintenance personnel are the star, from the silence behind the scenes to today's talent displayed. Hotwon operation and maintenance team will continue to take stability, safety and high efficiency as the three basic points, and to ensure the safe and stable operation of all facilities and systems in IDC as the objective of infrastructure operation and maintenance in 7*24-hour, and provide customers with high-quality operation and maintenance services; Continue to shoulder the mission of "no downtime, zero failure and data security" to protect the data age.

This is July 24th, which belongs to Hotwon operation and maintenance personnel. Even in their exclusive festivals, they are still on standby. This is the responsibility and duty of Hotwon operation and maintenance personnel, who interpret their mission with their actions. They are "Long standby" for 24 hours a day, 7 days a week. They can't let their guard down for any minute, just to ensure the safe, stable and effective operation of IDC. They provided with their promises and actions to customers, and they are our respectable operators!
