Exalogic sysadmin documentation

Interesting article on how sysadmin tasks for Exalogic are designed to be hours instead of weeks.  This also has a link to the Exalogic Enterprise Deployment Guide, and a whitepaper PDF (yes that seems to be a reoccurring theme lately) for Managing Oracle Engineered Systems - Exalogic (Physical) that has sections titled "How is Exalogic different?", "Monitoring and Alerting" and "Tuning" which may be of interest to you.  Until now, I'd never heard of Exabus but now I know something about it.  Do you?
