The more the data center grows, the more dangerous it becomes
The new challenges of data centers
In recent years, extreme climate, epidemic situation and technological development have also brought new challenges to the high reliability of data centers. Practitioners face these new variables, must be vigilant. Based on previous visits and understanding, the summary is as follows:
The larger the data center, the more difficult the operation management is.
The construction of data center shows the trend of large-scale and intensive. In recent years, few new projects are small or medium-sized data center. Most are the large, super-large data center park, multi-stage construction completed.
And data center system is huge and the management is complex, with HVAC system, power system, weak electricity system, fire system... ... A 1,000-cabinet data center would have 100,000 test points. As the scale increased, the time spent on patrol and the difficulty of troubleshooting increased exponentially. It was easy to create omissions and blind spots, which could lead to safety accidents.
High power and high density, emergency time is compressed.
As the data center disaster in the Azure East, when data center cooling malfunctioned, the temperature in the machine room kept rising, and the servers went out of whack, if the operations team couldn't clean up in time, high temperatures cause server downtime and device damage.
In recent years, the power density of the server in the data center is increasing, the heat generated by the server under high load is increasing, the temperature of the computer room is rising rapidly, and the time of emergency treatment is compressed. “The temperature in the computer room can be raised by 3-5 ° C in 5 minutes, and by about 15-20 ° C in 20 minutes,” said one practitioner. “If the emergency response time that was once reserved for the operations team to locate and deal with problems was more than 30 minutes, now it has been reduced to 10 minutes or less.”
Extreme weather is frequent
The frequent occurrence of extreme weather in recent years, including drought, heavy rain and high temperature, has brought new challenges to the reliability of data centers.
The UK, for example, is a temperate oceanic climate, with a maximum temperature of no more than 32C, but this year it reached an astonishing 42c, “Much higher than the data center operators had originally anticipated”. Similarly, many areas in the north of our country do not have high annual rainfall, so there is no perfect flood response plan, some data centers even pump and other materials are insufficient reserves, did not take into account the water supply transportation problems. This year, Sichuan and other places suffered a rare drought, hydropower water partial dry, urban power rationing measures, some data centers can only rely on long-term diesel power generation.
