Clustering my two linux servers.

Hi... I have 2 servers. One is SuSE Enterprise Server 8.0 and another is SuSE Linux 8.2 . I want to make clustered Servers, so if one is failed (down) than the other will takeover the tasks of the failed server automatically. Any body have a good experience in doing that with SuSE Linux? I need a recommendation which product I should use. I don't want to be trapped into a device driver problem and I also don't want to be trapped into a usage complication. Please give me your advices... Thank you very much in advance. __________________________________ Do you Yahoo!? Win a $20,000 Career Makeover at Yahoo!
