Even though most professionals surveyed had built a new data center in the last four years, almost 90% of them said their racks were already three-quarters full. The vast majority of data centers (over 91%) have deployed high-density equipment to fully exploit the space available, but a worrying percentage are not adequately managing the power density of their racks, with an alarming 21% unaware of their maximum power density per rack. Data centers need to ensure that their rush to install high-density equipment is matched by a genuine ability to manage power and cooling. High density equipment helps the data center to keep up with the demands of business, but if organizations continue to operate close to thresholds, they can also dramatically increase the risk of outage. In many cases the widespread use of high-density equipment is putting a strain on data center infrastructure, massively reducing any margin for error, with human error remaining the number one cause of outage.
