My presentation for the Green application hosting workshop. Topic: how transparency in energy measurement leads to change in behavior. http://kngs.wikidot.com/events:ws-schubergphilis/

2. Transparency makes datacenter
sector stronger.
Jan Wiersma

3. Energy chain

4. The trigger (1)
• Directly charge customers for energy
consumption.
• But; do they really care ?!?
• So a little story…

5. The trigger (2)
• A Test&Development environment out of
control…
• A VM Sprawl…
• Solution; implement billing model…

6. Dashboard
• Provide the software / query developer with CPU, RAM,
Disk I/O and kWh usage

7. Setup
• HP c-class blades, ILO & AO – energy usage (ssh script)
• Other hardware, IPMI – energy usage
• Windows & Linux OS
• Oracle DB & Java
• HP OpenView, HP Insight Control - Dash board
• Vmware vCenter (& ssh script on ESX)
• Visual Sudio perf testing, HP LoadRunner (Mercury) – system&application
insight.

8. Other tools
• Microsoft’s Joulemeter – estimate energy usage
• Intel’s Energy Checker SDK – uses external power meters.

9. Result & To do…
20% less energy usage every time without a ‘real’ effort
• Virtualization;
• Crappy sensors;
• DTAP setup;
• The total application chain & architecture;
• Software & hardware choice.
So; providing measurement and control (with a little financial stimulus) leads to results

10. Integration
• Integration between
hard&software
• Lots of quality data available at
the DC facility level.
• Integration between facility and
IT is key for the future

Options
10. Converged Infrastructure
10. Infrastructure Intelligence Intelligence
(Convergence)

12. 10. CONVERGED INFR. INTELLIGENCE
• UPDATE: The Data Center Infrastructure is becoming a complex
machine requiring connection up the stack
• Treat the DC infrastructure as an IT system
• Converge in the infrastructure instrumentation and control
systems
• Connect it into the IT systems for ultimate control
• Standardize connections and protocols to connect components
• What’s measured and controlled will be addressed and tuned

13. Will they care ?
Cloud will drive green software
Pay-per-use will drive efficient software
