Top 3 Developments in Green IT

green it

We’ve seen quite a bit in the way of energy efficiency improvements in IT over the past decade. The fact of the matter is that going green has, more often than not, helped companies realize cost savings, at least in terms of their operational budgets. Add in the changes that manufacturers have made to make servers and other IT equipment more energy efficient, and it’s almost surprising to hear that IT power needs actually continue to grow each and every year.

Green IT and the data explosion

The biggest buzz in IT right now is data explosion. The web, cloud solutions, and all sorts of other data needs are growing exponentially. One industry group estimates that we will need as much as 50 times our current data capacity within just the next 10 years.

This all translates into needs for more storage and more computing power. This means more servers and more hardware, which is somewhat problematic when the goal is to reduce power needs.

The data explosion means companies need to take a more thorough inventory of their data centers, making sure that they have exactly the right type and amount of hardware, and that they’re using the right amount of power and cooling as well.

Hardware vendors and going green

Hardware vendors have a mixed track record when it comes to increasing efficiency. While servers today make better use of the power they have, we haven’t yet seen an overall decrease in the power used by the average system.

Still, we’re seeing interesting changes. Some companies are rearranging their motherboards, for example, by placing dual processors farther apart and allowing for more airflow. Every bit helps to reduce power and cooling needs.

Beyond PUE

PUE has been a workable metric for understanding how a data center uses its power. The problem is that PUE doesn’t always paint a good picture of efficiency. Just because a given facility might have a low PUE doesn’t mean it’s not wasting power or cooling. PUE is useful, but more and more data center managers are looking to other ways to measure the efficiency of their facilities, alongside or instead of PUE.
