Solaris x64 might be nice platform for running DB2 on Intel/AMD machines, including inside VMware or other virtual machines. And these days, I've heard, one can get support for Solaris on Intel/AMD from IBM, HP and other server vendors. That support should not be more expensive than the one for some enterprise Linux flavor. I am about to start testing it.
Sorry for OT from serious topics of this discussion.
