Questions, and Answers from the Tutor
Question: What might the average Fortune 500 company expect to save annually from implementing virtualization in its domestic operations?
Answer: This question can't be generalized to such an extent, because there are so many variables involved with how a particular Fortune 500 company implements virtualization. But from the discussions I've had, the savings for your average large enterprise can range anywhere from 10% to 60% -- more than enough for most companies to cost-justify virtualization.
asked by Michelle Hazelton
Question: Are there native software settings in either operating systems or applications that enterprises can use to help reduce the amount of energy a server uses? If so, what are some of your favorites?
Answer: I haven't looked into this issue in enough detail to provide a detailed answer. The link below provides some detail of a recent study performed by Network World that compared a few different operating systems relative to power efficiency. http://www.greenercomputing.com/news/2008/06/12/linux-touted-most-efficient-server-operating-system
Question: Thanks for the tutorial. It was really enlightening. It seems from the tutorial that the motivation for Green IT may not be for the good of the environment but rather the perceived financial savings for implementing Green IT technologies.
You mentioned that virtualization could be most important to green IT, but the article below actually shows that virtualization can lead to increases in heat and power consumption. Can you just reconcile this difference? Thanks.
The hidden costs of virtualization
Paul Whyte
Answer:
Good questions. The answer to the first part of your question is, honestly, both. The primary drivers are cost savings and operational efficiencies, while the benefit is lower energy usage, which is positive from an environmental perspective. Ultimately, the vast majority of enterprises out there looking to deploy any type of new initiative need to have some sound business reason to do so, which Green IT provides in many cases. As for your question about virtualization, if you could point me specifically to the point needing to be reconciled I'll take a look and get back to you with more detail.
Thanks,
Rick
