Westmere-EX has one memory controller per socket ... and there are glueless systems up to 8 sockets. So 8 there. Not sure if any OEM is building larger machines with a node controller (SGI? Not sure if they build their behemoths from -EP or -EX parts). Ivy Bridge ups the ante with two memory controllers on a socket. So plan on doubling soon. -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
