Production Cluster Examples
===========================
Production clusters for petabyte scale data storage may also use commodity
hardware, but should have considerably more memory, processing power and data
storage to account for heavy traffic loads.
Dell Example

A recent (2012) Ceph cluster project is using two fairly robust hardware
configurations for Ceph OSDs, and a lighter configuration for monitors.
