1. The Greening of IT
November 1, 2007

2. Why the Concern? Cost of energy is rising
Costs more to cool a server than to power it
Data Center Energy Demand Increasing
Regulatory Agencies Looking at Data Centers
Environmental Benefits from Reducing Carbon Emissions

3. Today’s Data Center A Perfect Storm Of Challenges
Increased server density
Smaller, more dense form factors
More heat, same space
Moore’s Law marches on
Increased power consumption
More heat generated
Replacement cycle mismatch
Data center ~ 10 years
Server ~ 3 years
Organizational issues
Separate decision markets
Power and cooling typically part of facilities
IT departments moving towards SOA
Increased business agility
Increase focus to control costs

5. Issues you must consider
Where Should you Begin?
Issues you must consider
Strategies
Space constraints
Virtualization / Consolidation
Limited data center power
Blade systems/Optimized servers
Increasing cooling loads
Dynamic provisioning
Tracking consumption
Power Management

6. Optimizing Through Virtualization
What Drives Savings?
Virtualization may reduce power bill by 30% to 40%*
Consolidation of server applications
Average processor utilization is only 25%
Virtualizing your clients
Move from 120W fat client to 20W thin client
Power Supply higher efficiency increases utilization
Optimal power supply load is 50% or higher
Distribution of consolidated resources in data centers
Balanced thermal profile through data center
Conversion
Powering IT
Savings
Cooling IT

7. 64-Bit – Leveraging Multi-core Servers
Leverages the full power of today’s latest systems
130% increase in users per server
When using quad processor (dual-core) servers

8. One Approach to Reduce Cooling
Front Intake Sensors- measures rack intake air temperature
Base Station-compiles information from intake and exhaust sensors
