Subject Re: Running multiple instances of Cassandra on each node in the cluster

It works fine, and there can be meaningful performance benefits if you have
a sufficiently large machine where either you have so much RAM or so much
disk that a single instance would likely underutilize those resources. You
can configure it by adding multiple IPs to the servers, and running one
instance of cassandra per IP.
