Hi Garret,

Do you have the virtualization features (i.e. AMD-V) in the BIOS enabled? In many cases they are disabled by default. You might also try the new [A href="http://itknowledgeexchange.techtarget.com/virtualization-pro/new-sitesurvey-utility-from-vmware-checks-for-fault-tolerance-compatibility/"]SiteSurvey utility [/A]which might be more accurate.

Ran the CPU Host Info utility against a HP DL785 G5 that has AMD 8360 SE which is a Barcelona chip. Says the host is not FT compatible… Hmmm…

You can depending on how you are using MSCS, FT provides protection against a host failure but not an application failure.
