After hosting a round table event aimed at addressing some of the industry’s key topics, Keysource has created white papers that look in depth at two of the operational challenges facing the industry. ‘The Use of Fresh Air in the Data Centre’ and ‘Raising Inlet Temperatures in Data Centres’ papers highlight the impact of these challenges and the potential solutions that were discussed to help facilities and data centre managers make informed decisions and effectively manage their businesses. Joining us at the event were: the Uptime Institute, Operational Intelligence, Fujitsu Colt, Vocalink, Norland Managed Services and The 451 Group.
The Use of Fresh Air in the Data Centre
The first item on the agenda was the benefits of using direct fresh air vs traditional re-circulating cooling systems. Consensus was that there is very little to choose from between the two systems in terms of operational efficiency but across the industry there is a move towards chiller-less systems. The event highlighted that in some situations, companies were opting for the perceived environmentally friendly chiller-less systems without first fully evaluating the risk profile.
You can find out more and what the experts also had to say on CAPEX and resilience implications, maximum peak PUE or power demand by requesting the Keysource white paper; The Use of Fresh Air in the Data Centre.
Raising Inlet Temperatures in Data Centres
Looking again at data centre efficiency, this white paper highlights the potential benefits of raising the inlet temperatures to increase cooling efficiency. Testing by one of the experts at the round table has shown that temperature increases above the recommended 27o to 40odid not result in significant failures of any kind, but did increase energy efficiency because of the reduced running time of the coolers.
Whilst this may seem like an option that is not viable for most data centres it was agreed that increasing the inlet temperatures by just a couple of degrees would also have an impact on the operational efficiency of the data centre. Effective monitoring of the temperature and humidity of the centre would also allow for increased efficiency by regulating chiller use to only periods when it is required.
All attendees agreed that operators need to be fully informed before making a decision to increase inlet temperatures and that the proper elements need to be in place before making a decision.
