There's a new case study out this week on the University of Canberra's use of virtualisation in their data centre. There's plenty of detail in the case study of what they did (and which products they used, basing it on the Hyper-V virtualisation system built into Windows Server 2008 R2). Rather than dive into that detail, I think the key thing to look at is the way that they have built a much more flexible IT infrastructure for the university, which along the way has virtualised 60% of their servers, including their Red Hat Linux ones. According to Tom Townsend, the IT Data Centre Manager at the University:
We now have a flexible, responsive IT environment, which positions us to grow and change in line with the demands of today’s dynamic university environment. This makes us more agile. We can implement the technologies we want as soon as they become available. From a business perspective, being able to trial and commission new services quickly gives us a real advantage.
We’re managing a much larger number of servers with fewer staff.
They've also reduced the power and cooling running costs of their data centre by 20% - a significant contribution when electricity rates are continuing to go up.
