As your server setup and data centers grow, having a solid data center cooling system in place becomes increasingly important. Whether you're considering adding one to your own in-house data center, or shopping around between third-party centers, having a modern and well-maintained data center cooling system will reduce downtime and save money in the long run.
Heat, of course, will tend to build up among any collection of electronics, with more heat being generated as the collection grows. This problem gets worse if the data center is in a relatively small room, leaving the rapidly-warming air with no place to go. Further compounding the issue is that server and data center equipment tends to be less heat-tolerant than off-the-shelf consumer gear, so overheating can quickly become a very costly problem.
