A few weeks ago I’ve referred to an article from Joe Wagner where he discusses virtualization (and the need to manage virtualization), and in the past year Jeff Jaffe has written many blog posts about it. Now this week IBM announced they will be spending $1 Billion per year to dramatically increase the level of energy efficiency in IT and they have indicated that virtualization will play a key role in their plan’s to get to the “green” datacenters.
Why is virtualization so important?
Today I saw a blog post from Dan Kusnetzky where he mentioned the following:
One of the primary goals of almost all forms of virtualiztion is making the most efficient use of available system resources.
Suppliers of management software for virtualized environments have the ability to move workloads to a smaller number of servers when workload and service level agreements allow it. Then the unused servers can be powered down.
Perfect explanation on what it’s all about, tanks Dan
