While some data center operators use liquid cooling to make their facilities more efficient, most of the growth in adoption of these technologies is driven by the need to cool higher-density racks. But the switch from air to liquid isn’t simple. Here are some of the biggest barriers to adoption of liquid cooling in data centers: It requires not one, but two cooling systems; there are no standards; some use warm or chilled water, which poses an electrocution risk; the water causes corrosion; and the systems are complex.
