Yah, Velocity has a clue, we did most of the performance research and testing for the Oracle/XIP redbook. If your system is already tuned with the easy stuff and you already understand how to manage virtual machine sizes, and you use vdisk for swap, then you could save something using XIP. Otherwise, sorry, don't bother for 20 servers.

At this time we are looking at about 12 to 15 Linux guest divided across two lpars. It is my understanding the Linux guest will be running WebSphere and Oracle. I have found some information on setting up the environment. The doc talks about performance gains and memory savings that has some people here interested in looking at DCSS. We are running z/VM 5.1 and SuSE 9 sp3.
