Please define your concept of High Availability - people have different ideas on these buzz words. > Some of the question I am looking at in a practical viewpoint of an > Application and IT infrastructure Architect are: > > 1.

For a Proof of Concept this can be achieved with mid range desktop(s) that support Linux KVM. (system board + cpu cost 13-15K). > Would anybody like to join me in presenting a paper or experimenting? I think it would be better if you first present an executive summary of your paper/experiment. Best, -- Arun Khan _______________________________________ Pune GNU/Linux Users Group Mailing List
