Here’s something you don’t hear every day. Women working in data centers actually make more than their male peers, at least according to a new survey of 310 data center professionals worldwide.

A pertinent caveat: Just 11.7% of the respondents were women, but on average, those respondents made 17% more than their male counterparts across all ranges of experience and titles. The salary disparity broadened at the higher levels of management. (See the chart below.)

Salaries of data center pros handling lower level data center operations and infrastructure duties (often called racking-and-stacking in the industry because this job entails installing lots of servers in racks) were lower than for people with application development and cloud computing experience, according to research conducted by Stratoscale, an Israeli company specializing in data center networking.

Salary survey

The findings were based on a survey completed by IT professionals worldwide in February. The bulk of respondents were between 25 and 45 years old.
