Far from expert opinion, however one configuration I have seen talked about
is 3 x m1.xlarge in AWS.

I have tested 4 x m1.xlarge and 4  x m1.large. The m1.xlarge was fine for
out tests (we were hitting it pretty hard), the m1.large
was eratic - from that I took way that you either need to give Cassandra
sufficient resources or know how to tune properly (I don't)
