The idea of memcached is to use vast quantities of cheap PC memory to reduce latency to the very minimum. Putting it on Z seems bizarre given its got fast I/O and very very expensive memory which are exactly what memcached is not designed for. I'd have thought a pair of PC class boxes with ECC RAM would be a better fit.
