I was honored to speak at LinuxCon North America in beautiful Vancouver yesterday, about one of my favorite topics -- energy efficiency opportunities using Ubuntu Servers in the data center (something I've blogged before).
I'm pleased to share those slides with you today! The talk is entitled PowerNap Your Data Center, and focused on Ubuntu's innovative PowerNap suite, from the system administrator's or data center manager's perspective.
We discussed the original, Cloud motivations for PowerNap, its evolution from the basic process monitoring and suspend/hibernate methods of PowerNap1, to our complete rewrite of PowerNap2 (thanks, Andres!) which added nearly a dozen monitors and the ubiquitously useful PowerSave mode. PowerNap is now more useful and configurable than ever!

Stay tuned for another PowerNap presentation I'm giving at Linux Plumbers next month in California. That one should be a bit deeper dive into the technical implementation, and hopefully generate some plumbing layer discussion and improvement suggestions.
