14629578_sUSA: Spending on data centre systems is projected to reach $143bn in 2015, a 1.8% increase on 2014.

The figures are revealed in a new report by US information technology research and advisory company Gartner.

According to the report, worldwide IT spending is on pace to total $3.8 trillion in 2015, a 2.4% increase from 2014. However, this growth rate is said to be down from earlier projections of 3.9%.

Growth for the servers and external controller-based storage segments has been lowered from earlier projections due to extensions in replacement life cycles and a higher than previously anticipated switch to cloud-based services.
