I've seen DBs run on 128G machines on x6 and have no experience of such problems. Do you have a link or hard evidence of this? I have seen throughput issues on VMWare machines (and false reporting on standard linux utilities, eg "time" output and various other issues that make me distrust it for performance-sensitive software), but don't know if this is to do with 128G machines; usually it's to do with contention on one network card handling all traffic to disks.
