Guangzhou

Guangzhou No.1 Cloud Computing Base carried out emergency drill of emergency oil supply for two-way mains power failure, and verified the stability of automatic logic function of high and low voltage distribution system, the endurance of diesel engine with load and the timeliness and reliability of emergency oil supply to fully check the emergency oil supplier's emergency oil supply ability, check whether it can meet the long-term on-site load demand, ensure the stable and safe operation of the computer room, improve the on-site emergency handling ability of operation and maintenance personnel and the response speed of suppliers, and reduce the risk of unnecessary human failure.

Guangzhou No.2 Cloud Computing Base carried out emergency drills for refrigeration unit failures, which verified the quick, orderly and efficient emergency handling ability of operation and maintenance personnel, ensured that operation and maintenance personnel were familiar with emergency procedures, strengthened the memory exercise of operation and movement, reduced unnecessary human failure risks, and scientifically and standardly responded to emergencies.

Guangzhou No.3 Cloud Computing Base carried out drills for sudden interruption of municipal water supply, and the operation and maintenance personnel responded quickly. After on-site inspection and confirmation, they timely judged the cause of interruption and made recovery plan, checked the water storage capacity and shut off non-essential water supply. HVAC engineers informed the emergency water supply unit to send water supply trucks for emergency water supply as needed, and continued to pay attention to the water level of reservoir, the operation status of computer room equipment and the temperature changes of hot and cold passages before the municipal water supply was restored, and gave feedback and notification until the municipal water supply returned to normal. During the whole drill, all the operation and maintenance staff cooperated tacitly, organized clearly and divided clearly. They used the vertical reporting and horizontal reporting mechanism to quickly report and direct multi-threads for emergency disposal, which verified the reasonableness and practicality of the emergency response plan.

Chengdu

Chengdu No.1 Cloud Computing Base conducted emergency drills for single UPS failure of UPS parallel system, which verified the high reliability of UPS system, the practicability and rationality of emergency procedures and emergency tools, and at the same time improved the emergency handling ability of operation and maintenance personnel in case of UPS failure.

Hangzhou

Hangzhou No.1 Cloud Computing Base conducted drills that the temperature of the cold channel of the computer room was too high. When the temperature continued to rise beyond control, immediately started the emergency plan and the cooling fan, and urgently contacted the ice supplier to supply ice, so as to control the temperature of the cold channel of the computer room within a reasonable range. During the whole drill, all the operation and maintenance staff worked closely and clearly, which verified the effectiveness and operability of the emergency response plan.

Ningxia

Ningxia No.1 Cloud Computing Base checked the preparation of emergency reserve materials needed to deal with emergencies by carrying out emergency drills for water leakage, and adjusted and supplemented in time if any shortage was found, so as to enhance the familiarity of data center operation and maintenance staff with emergency response plans and improve their emergency handling ability.

The core idea of Hotwon's operation and maintenance is "preventive maintenance", always insisting on and implementing basic maintenance, dealing with hidden dangers and faults in time, carrying out emergency drills in advance and optimizing emergency response plans, so as to provide efficient, high-quality and reliable operation and maintenance services for customers. Thanks to the joint efforts of all Hotwon operation and maintenance personnel, this emergency drill for joint operation and maintenance in all districts was a complete success. The drill is to prevent emergencies that may occur in the operation and maintenance process, and to strengthen the emergency handling ability of Hotwon operation and maintenance team and the multi-party cooperation of on-site operation and maintenance colleagues.

They will exist at every place that needs maintenance,

with a label of safety and reliability and efficient operation and maintenance,

and with normal working conditions of quick response and being on call.

Today, let's dedicate our attention to them - the operation and maintenance personnel,

and express our respect to every super-long "standby" operation and maintenance personnel.
