> With that kind of problem, you may want to abandon x86 altogether At this end of the spectrum, that means abandoning commodity hardware, with everything it implies, not just a change in binary architecture, as it might for ARM vs. x86 in end user devices. Recently, I looked up the max memory on IBM's system z, and it was only 32TB, but it looks like their Power Systems E980 can take 64TB. It appears that, like with their mainframe line, going that route means significant vendor lock-in, including proprietary memory modules. It's certainly interesting that the current generation of high-end x86 CPUs took a step backwards from the last generation, in that that their max is 12TB and just catching back up to 24TB isn't expected to happen until next year.
