Real-Time Data Center Transient Analysis
Keywords: Data Center, Transient, Real time
The power and cooling systems of data centers have become critical components of highly available computing facilities. The delivery of electrical power supply to the IT equipment in the data center is typically supported by UPS and emergency generators which ensure uninterruptible computing. However, the cooling system will shut down for a short period of time during a power failure and may not be able to sufficiently remove the heat generated by severs. Even after generators beginning powering the cooling systems, it still takes some time for the facility ambient temperature to be adjusted back to the normal operating condition before the power failure. While cooling redundancy is crucial to maintain favorable environmental conditions, data center designers and operators should also consider the transient cooling performance during a power failure. However, it may not be well understood how the facility temperature changes during a cooling outage or after the cooling system is back online. This presentation discusses the transient response of data centers under many different design and failure scenarios. A software tool was developed to explore various alternatives in real time for data center design and management purposes.
