The Greening of IT November 1, 2007

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

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

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

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

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

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