PUE Calculator

The Power Usage Effectiveness Estimator or PUE Calculator is a tool that we are going to attempt to use here at Softchoice.  This tool will give us a numbered result that we can work into our reports at the end of the year and compare against future years to see how effectively we are using our power.  I will post more as I learn about this tool and make sure to detail the best ways to use it.  So far the most challenging part is getting a member of our IT team to sit down and help me out!  Check out the tool and let me know if you have used it before or have any quicker results.


Everybody’s working for the weekend

The five o’clock stampede thunders through offices across the county. People to eager to start their weekend or evening , to catch their train, liberate little ones from daycare leave their workstations in a hurry. Many of them not taking the time to power down their workstations. This uses up a lot of energy unnecessarily – increasing energy costs and unnecessarily burdening the power grid.

It happens everywhere – so if your organization is facing this you are not alone. We found an article in the ITAM review about energy expended through desktops being left on and things you can do to alleviate the pressure. For instance, printers can also be shut off during non productive hours and like PCs and certain servers … read more.

Facebook listens to their friends

Facebook has taken recent criticism seriously about their energy consumption. They have joined their IT cohorts to do the right thing  and have cleared the air in their data center by using fans to create better airflow management as well as containing this cold air to keep it escaping in the floors. This makes their systems more efficient and dramatically cuts the amount of energy they are using.

What we did here isn’t rocket science,” said Jay Park, Facebook’s director of data center engineering. “We applied very basic thermal theory.” He was on a panel discussing…read more.

Save your energy for Monday morning

Are your coworkers ending their days and starting their weekends by turning off their PCs? It’s an easy way to lower your carbon footprint and there are solutions available ranging from management systems you can buy to the tried and true method of clicking on the Windows logo.

But what about your servers? Ever wondered how much energy you’d save over a weekend if you turned off under-used servers during your off hours?  Software company IE is working on a server version of their management solution for PCs. They are inching closer to helping companies reduce their carbon footprint with a fail-safe power management system for the data center.  Read more.

Data center efficiency is more than hot air

Or is it? I just learned about an easy way to reduce cooling costs in the data center by using hot air.  The big problem with data centers is that they generate a lot of heat from all those racks of servers.  For every kilowatt used to run data center equipment, another kilowatt needs to be spent on air-conditioning to pull the heat out. Most datacenters are big rooms where cool air and hot air mix together.

So why not keep out the heat? The hot aisles can be blocked off with strip curtains, similar to ones used in meat packing plants. This allows  the hot air to be vented out of the building while the cool air can move through the data center – which means that instead of a 55 degree deep freeze, it’s could be a comfortable 74 degrees in the data center.  

One of our partners, NetApp, developed this setup which earned them an Energy Star rating.  You can read about it here:  http://www.environmentalleader.com/2010/07/15/netapp-first-data-center-to-earn-energy-star-for-superior-energy-efficiency/
