"Though the price of servers has come down, the cost of power is rising incrementally; about 31 per cent according to data from the independent organisation--Green Grid," said Raritan vice president, Asia Pacific and Japan -- sales and marketing, Chris McPherson, speaking in Malaysia recently.

"Adopting a green infrastructure approach does make immediate cost savings as well as give certain corporate brand positioning advantages," said McPherson. "However, the ability to measure energy efficiency is the real first step to managing power costs."

"In Asia, metrics of energy efficiency is very much at early infancy stage," he said, adding that companies in the financial and insurance industry were early adopters. "We are beginning to see companies in the telecommunications sector take serious interest in data centre power usage effectiveness [PUE]."

The founder of Raritan, which was established in 1985, Dr Ching-I Hsu, is considered as the founder of KVM (to allow control of multiple computers) switches, PDUs (power distribution units) and infrastructure technology."
