Clustering of machines is certainly possible. From a sales perspective
though, many organisations will choose a single install rather than a
cluster. Why? Cost. If the smallest cache is X dollars, having two costs
2X no matter the topology. If they are forking out for distributed
caches, their easiest answer is to have no end users on the centralised
site, only child caches, and they will handle failure gracefully.
