If I remember correctly they ran 16x > 386 and 8x 486 in a single box (under Dynix?) Actually they'd scale to about 30 Pentiums. But then again, note that I said normal and current. Our Symmetry boxes fit neither of those criteria ;-) M. - 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/
