What is innovation? Dictionaries define it as the introduction of something new or different to traditionally accepted practices, but with so many organisations around the world trying to make their business more environmentally sustainable, some of the modern ideas that we have seen introduced over time have become somewhat commonplace.
Go back to the beginning of the data centre, or computer rooms as they were more commonly referred to. Because of the low power densities, most of the rooms were laid out in rows with racks facing front to back. With time came ever-increasing loads and it was only until the orientation of racks were changed that the world recognized that creating hot and cold aisles would allow them to reduce the mixing of cold air delivery and the hot air return to the air conditioning system, thus increasing efficiencies; an innovation of its time.
Fast forward to the present day and hot and cold aisle containment is more focused and more concentrated. With higher rack densities it is now considered crucial that in order to provide the best efficiencies, it is no longer enough just to cool the room. Aisle containment provides that degree of separation to minimise the cold air supply and hot air return from mixing. Whether it’s by using conventional perimeter located CRAC units or in-row cooling, aisle containment delivers better efficiencies for the cooling system, saving energy and operation costs.
