      * adding iostat reports to ganglia would be useful to track the IO during full processing with OTA/skycells processed locally and to verify tests.
      * more details on the raid config for active machines will help as well

+ * ippc18 - odd 5-10min oscillation behavior in cluster load reducing throughput ~40-50% from 2am-6am. was rsync ippc18->ippc19 mirror. Bill rotated logs so rsync only takes a fraction of the time. Rsync also moved to start at 6am so if happens again, isn't buried in wee morning hours. Rsync niced and a bandwidth limit of 10MB/s also added.
