Case Studies

As hints and tips for linux under VM are discovered, appropriate analysis will be done in the form of case studies. The following case studies can be viewed:

Idle Server Costs:
Operating many linux servers has a cost, even when the servers are idle. These costs can be reduced, but you may want to evaluate the costs and include them in your capacity planning. Idle Linux Costs

Reducing Storage Requirements using VM Features:
An experiment was done using a standard 128MB virtual machine. The working set was immense, paging load was extreme. The experiment was then performed using a 24MB virtual machine and a swap set on virtual disk. The elapsed time went from 5 hours to less than an hour, there was no paging, and the working set was not a problem. Virtual Disk Analysis
