The new software from Status is what I didn’t know about, and I can’t wait to have a closer look into. You are right about the limitation with software based FT technologies for supporting SMP, Marathon doesn’t support that as far as I know, but for the VMware’s FT coming with vSphere I don’t know yet, that’s something we’ll have to wait for the final release to confirm. Regards Hi PhilR,

Running off the shelf Windows on standard Intel Xeon in full hardware lockstep. The platform also runs Red Hat Linux and as of January 2008, VMware ESX, and can support full SMP, something the software “FT” solutions can not do (scale beyond one core!). No need for multiple OS or application licenses, no scripting, no special skills required. Just plug them in and you get real FT out of the box.
