The amount of virtual machines you're going to be able to populate on a machine is really dependent on the type of application your deploying and its utilization. I have one server with 8 cores @ 2.6GHz and 64GB of RAM and get a consolidation ratio of about 35:1 running small COTS applications and other tasks like IIS/.NET/Sharepoint --- but on the same type box running SAP I only get a consolidation ratio of about 10:1 so--it REALLY depends on what your deploying. For vendors to say YOU'LL GET 35:1 is really bad business...they really should be asking their customers what they're going to deploy, before making assumptions.

The vendors claim is based on some theoretical set of parameters which do not work in the corporate environment. The main advantages of virtualization is the increase in utilization, reduction in space, energy, cooling costs, RAS features. Wish the vendors would highlight these and sell based on some other metric other than the number of VM's. False promises are made to IT management and the operations staff/users struggle with poorly designed VM's which address the promise made by marketing people rather than reality.

It is good to see articles like this. For those of us just getting into the field virtualization is something new that they haven't started teaching in most universities even though it's actually been around for years so it is always good to see what enterprise admins have to say on the subject.
