Keeping cool is the number one cost for data centers. With rows and rows of servers and equipment producing heat, data centers have traditionally been cooled by using air conditioning. This is an inefficient way to cool data centers and consumes a lot of power.
As energy costs continue to rise, CIOs and data center managers are looking at all possibilities to become more energy efficient.
An interesting trend to lower data center cooling costs is building data centers in regions that offer cool bodies of water and cooler air temperatures.
