Jon, In the distant past there was a problem that if you told the kernel that it was SMP it would crash on uniprocessors. I think that may have been fixed though. Basically the best thing to do is to simply try running an SMP kernel on a few uniprocessor machines and see what the latency is. I do feel that if EMC supports both SMP and non-SMP kernels they should be the same kernel revisions. There are some kernel switches which turn off the exact kernel matching for module loading, but that might cause more trouble than it is worth since you would likely get issues where someone later runs the wrong module version and things become unstable... Hope that helps. EBo -- ------------------------------------------------------------------------------ Special Offer -- Download ArcSight Logger for FREE!
