Going Green


From the article:

Return on Investment… the holy grail of IT.

Simply put, ROI is defined as the “ratio of money gained or lost on an investment relative to the amount of money invested”. One formula used to determine ROI is “net income plus interest divided by the book value of assets equals Return On Investment.“

In real terms, when you invest in a technology for your business, it’s about more than that. IT-related ROI often needs to provide cost savings, rather than generate revenue. In the case of virtualization for consolidation, this is often a simple calculation made difficult by many variables.

The emergence of global standards for measuring the energy efficiency of datacentres moved a step closer yesterday with the launch of a raft of new research papers from green IT industry consortium The Green Grid.

The consortium has released an updated version of its Datacentre Energy Efficiency Metrics whitepaper that incorporates infrastructure efficiency into the original metrics.

It also said that it expects its Power Usage Effectiveness (PUE) and Datacentre efficiency metric for assessing the proportion of power going into a datacentre that is used to power the IT kit to be adopted by the industry and used by all datacentres to report their efficiency.

Sick of hearing about “Green” yet? Better learn to deal with it, “Green”‘s drumbeat is really just beginning and it’s not just a fad, it’s something that fits a condition we have in IT, and it’s a way to get more money and headcount for managers, so listen up.

What is “Green” computing? Here’s as good a definition as I could find, click through for more from Techtarget.

Green computing is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste).

One of the earliest initiatives toward green computing in the United States was the voluntary labeling program known as Energy Star. It was conceived by the Environmental Protection Agency (EPA) in 1992 to promote energy efficiency in hardware of all kinds. The Energy Star label became a common sight, especially in notebook computers and displays. Similar programs have been adopted in Europe and Asia.

Last but not least, is buying “Green” storage for business continuity, disaster recovery and archival enough? Not nearly enough, according to the marketing director of Overland Storage.

Never one to do anything in a small way, CSFB has plans to continue their use of virtualization using rations of up to 15:1.

“With 20,000 servers to manage, financial services powerhouse Credit Suisse had a long list of reasons to consider server virtualization: reducing the number of physical servers to manage, cutting power needs, improving software provisioning time, and deferring expensive datacenter buildouts. But it also needed a clear set of guidelines to determine when to virtualize, plus a clear set of procedures for managing a virtualization initiative.”

Nationwide Insurance is a posterchild for the right use of virtualization, on all their platforms. A huge IBM Mainframe shop, they also use Linux in their X86 environment to cut costs and be more green.

“While many IT shops see virtualization as a question of adopting EMC’s VMware on servers running Windows or Linux, Nationwide Insurance has adopted the technology for both x86-based and mainframe-hosted servers.  After all,” notes Buzz Woeckener, the company’s zLinux/Unix server manager, “virtualization was invented for mainframes.”

There’s a great new site called LessWatts.org, whose goal is to help Linux users use less power through a variety of means. The mission statement is pretty straightforward:

Saving power is a hot topic across the computer industry. For some, saving power means getting a longer battery life on their mobile devices, be it laptops or handhelds. For others, saving power means reducing costs and increasing efficiency in their data centers. For all of us its about reducing the impact of computing on our planet.

The site is surprisingly engaging in light of it’s laser focus, you’ll find:

As an example of the great tools you can get from this site, PowerTop is a version of the /bin/top utility that monitors power consumption on a process by process basis.

PowerTop has 4 basic goals:

  • Show how well your system is using the various hardware power-saving features
  • Show you the culprit software components that are preventing optimal usage of your hardware power savings
  • Help Linux developers test their application and achieve optimal behavior
  • Provide you with tuning suggestions to achieve low power consumption

It’s easy to use and install, and very quick to download. Take a look at the site, see what tools you can use and definitely read the documentation and FAQ section, it’s got some very useful information.

Enjoy,

Check out this cool little PC with an embedded Linux OS, all the basic functionality that a home user might need — especially if they’re just into web browsing and email.  No moving parts means it should be pretty durable, and it’s small enough for a frog to sit on.  They even market the device as being “Green” based on its ability to reduce power consumption.

It’ll be nice to see how this fares with home users… Check out their website for details and even a video demo of their OS.  Zonbu PC
