I have to back what Adam said from a managerial context. There has been much discussion in recent weeks about virtualization as to how it is (or can be, or SHOULD be) a cornerstone of your D/R scheme and exercises. But the burden cannot be entirely on the D/R site to emulate production. The production site needs to be designed with D/R in mind, including some homework: look for hints about those performance pain points. The performance issues cannot be ignored, but I have to think that we're about to enjoy more paravirtualiztion in Linux-on-VM (like the DIAG driver for DASD). Alan, pass me more of those pancakes! Adam? More syrup? -- R; <><
