Really, an Opteron based blade with samsung SSD instead of simply booting from SAN?
I'm pretty sure I'll stick with Xeon and SAN for these configurations since there just doesn't seem to be a reason to bother.
Do you really want to gamble on buying 50 or more dual processor blades that use a processor that has a high risk of not being able to upgrade the processors at least once before replacing the blades? I just don't trust AMD to be able to continue their semiconductor design division. That and the fact that they're so quick to release something new these days that they seem to be willing to push just about ANYTHING out the door.
AMD will be a terrible loss to the technology world, but hopefully there will be some new x86 upcomers.
