sorry, its about virtual servers that you can expand the number of processors, memory and hard disk size, when you need that, without reinstaling all things of hosted OS again, its will be installed in a datacenter, but works like http://www.vmware.com/products/vsphere/
I asked a similar question in thread MaxDB and virtualization.
At the time, not all versions were supported.
Anyhow, the official supported versions have to be 7.6.4.x or higher - so 7.6.5.x from the SDN Download will be perfectly supported with VM scenarios.
Since then , I have MaxDB 220.127.116.11 running in virtualized systems.
