As you may be able to tell there is a heat wave happening in the UK! Throughout this week the temperatures will be increasing reaching a peak on Thursday. The Met Office has issued a Level 2 Heat-Health warning to prepare the public for the weather. While the temperatures may not be high compared to many places around the world, the UK is used to a more moderate heat and infrastructures are designed with this in mind.

Older data centres and computer rooms often start to overheat and fail in high temperatures, as the air conditioning struggles to cope with the increased heat levels and cooling. These facilities are also likely to be full to capacity. In a facility that is already on the limit of cooling, a heat wave becomes very dangerous, especially if a CRAC Unit (Computer Room Air Conditioning) were to fail. Old servers are also very sensitive to fluctuations in temperature. Increased heat requires the internal fans to spin faster to cool the equipment and if a fan stops working, a server can very quickly over heat and shut down. If any 1 server has business critical applications on it, you should be prepared.

Migration Solutions created a health check for data centres and computer rooms which looks at all aspects of a facility and gives it a scored rating. The ERA report comes with an entire section on improvements that can be made to help your Data Centre run more efficiently and effectively, and can identify possible problems that could result in down time. These improvements range from free, low man-time changes that can yield a 5-10% reduction in power costs to major works which include changing a facility layout, rack layout and replacing old plant equipment. An essential part of Data Centre management is preparing for the worst, and identifying the strengths and weakness of your facility is key.
