As co-ops with IBM Developer Relations, our duties involve helping out the technical support staff to answer customer questions (in other words, we help the Help Desk). We work primarily with IBM WebSphere products -- and one situation we have encountered often is the need to tweak machines to re-create actual customer problems.

Re-creating each problem literally means having the exact same system as the customer, and it is of course much more efficient to do this by partitioning and running multiple systems on each drive, than to have a separate box for each system. And so, some many months ago, we converted from the one-box-per-system method to multiple systems on each box.

Now we can (for instance) run two different versions of IBM WebSphere Application Server on the same OS. All that is needed is to partition a large drive (ours are generally 19G in the lab) into two halves, install the operating system on each partition, then install a version of Websphere Application Server on each partition. Thus, we have have multiple copies of similar environments running on one machine.
