All the IT infrastructures on this world are responsible for 2% of the co2 output of this worlds societies. Which is equal to the co2 output of 50 million cars. [1] So in my opinion every company and every government agency should try to minimize the energy consumption of their IT infrastructures. But this isn’t easy… » Read more: greening your IT

greening your IT
March 31st, 2010Should we really think about making IT green?
October 28th, 2009Brian Madden published a really nice article about the green thinking in IT and how it concerns desktop virtualization. This article ends with the following questions:
What about you? Does the whole green thing actually affect the IT department in your company? Do you pay for power? Do you do things just because they’re green? Do you even care whether VDI is more or less green? Should we spend any more time on this?
I want to answer that with: I do really care about our little planet and i know, that all the IT on this little planet is consuming more and more watts every single day (If you look @ the sales of servers and computers in general you can imagine, that power consumption of IT is growing fastly…). I know, that we are (compared to the world in 2020) just @ the beginning of an “IT-lized” world. And that’s why it is definitely worth it to think about every watt that could be saved!
calculations on VDIs…
August 15th, 2009[For the german/original version - please click here.]
As a fan of saving energy in IT infrastructures, I have calculated how much energy one can save via implementing a VDI. Below is a detailed VDI solution used as an example to prove exactly how much energy can be saved. In order to better explain this, I will assume the following:
- the system-integrator configures an automatic shutdown for the hypervizor overnight
- no shared storage is used to store VMs because you don’t need high availability functions for all desktops
- the workloads we have to virtualize are average office users using a software that does not run on terminal servers but we can serve 4 desktops with one CPU-Core
