The datacentre spend in Australia is expected to grow from $2 billion in 2010 to $3 billion this year, according to DPSA national datacentre architect, Jason Rylands.
Rylands was speaking at a recent DPSA event held in Sydney.
“It is one of the fastest growing IT segment. We expect a further global growth of 4.7 per cent next year. Many new datacenters, expansion programs and amalgamations are on their way and energy efficiency is a he priority in this space,” he said.
Rylands claimed that about 25 per cent of an IT company’s total budget is spent on datacentre space.
He said IT companieswithin the space were facing a shift towards high-density datacentre solutions.
“Big data is one of the buzz words going around in the industry. A huge amount of data is exploding out of the networks. By 2015, 91 per cent of all Internet data will be video, and mobile devices is what’s driving the back end of datacentre expansion,” he stated.
He also said that the Cloud is another driver.
As a result, businesses are using a lot of energy to run these datacentres and technologies associated with it.
Rylands said that enterprises are using about 41 per cent of their power usage just for cooling datacentres and in comparison, only 26 per cent for PC and servers.
“When you start to look at where the power is being used, you quickly identify where the savings are going to be made – and that is in the datacentre cooling side,” he said.
In mid 2012, as part of the national initiative managed by the NSW Office of Environment and Heritage, National Australian Built Environment Rating System (NABERS) will include a rating system for datacentres.
However, he said that there are three challenges datacentres currently face. They include:
- technology compaction, that impacts rack systems
- technology convergence, that drives a mix of rack mounted equipment
- increased pressure on datacentre availability, efficiency, planning, operation and going green.
Rylands said working through the challenges will enable businesses to substantially save on energy bills and allow them to maximise its use it more.
“The best practice now, is for them to build datacentres for their current requirements and then scale vertically before going out horizontally as required; they should also re-use heat, for example, in co-generation; and meter, monitor and measure all energy use,” he said.
According to him, most of the savings can be derived from the virtualisation end – from 10 to 50 per cent in savings can be expected.
Going forward, Rylands claimed that there should be in more ICT and DC infra-alignment and more intelligent measurement and reporting in maintaining energy efficient datacentres.
