Micro data centers are essentially exactly what they sound like. They use racks and a much smaller footprint. Some of these micro data centers sit in cases that look like gun lockers. Others are mini racks with integrated systems. At a Schneider Electric conference in New York City this week, there was one mini data center design that sat in what looked like an entertainment center. Yes folks, in the future there may be a data center sitting in the middle of a store or bank branch.
