1 Power & Cooling Considerations for Virtualized Environments Cisco Data Center Day

2 APC-MGE Vision & Mission OUR VISION APC-MGE products ensure availability wherever data is created, transmitted or stored.from desktop to data center to factory floor. OUR MISSION To create delighted customers by improving the manageability, availability and performance of information systems and key process controls through the rapid delivery of innovative solutions to real customer problems.

3 Gartner CIOs: Undeniable Trends 70% of respondents recently said power and/or cooling issues are now their single largest problem facing their data centers Projections are 48% of data center budget spent on energy, up from 8% All other combined Top Issues Power and Cooling

4 Benefits of Virtualization Increased CPU Utilization/Efficiency Typical server utilization rates are approximately 10-15% usually higher in storage. With Virtualization, utilization rates as high as 80% Server Consolidation Decreased need to purchase additional servers Increased Rack space Reduced data center space requirements Improved Continuity & Disaster Recovery Virtualized servers can be mirrored in case of failure Reduced Labor Costs Associated with hardware provisioning and maintenance

5 Impact on Power & Cooling Reduced overall bulk power & cooling requirements Existing room- level UPS/Cooling wastes $$$ energy Higher burden on cooling distribution = Hot spots Blades and 1U appliance servers Need for row/rack/ U level, real-time visibility to dynamic environment Power and cooling capacity thresholds Physical and environmental threats

7 Reduced bulk power & cooling Potential Energy Impact 60 kw IT load 50% loaded physical infrastructure (120 kw) Data center efficiency 28.1% Annual electrical bill $217,926 $217,926 Before Virtualization

8 Low Density Raised Floor Room Cooling with Hot Aisle / Cold Aisle Arrangement Only 2 kw per rack Room design has worked well in low density rooms

9 Reduced bulk power & cooling Potential Energy Impact 60 kw IT load Data center load 50% Data center efficiency 28.1% 3:1 reduction ratio 20 kw IT load Data center load 17% Data center efficiency 13.1% $217,926 Before Virtualization 27% $ savings $159,290 After Virtualization 3:1 reduction in servers ~3:1 reduction in rack utilization Annual electrical cost $159,290 Only 1.4:1 electricity consolidation! Data center efficiency drops to 13.1% Electricity Savings per Year: $58,636 (27%)

Data center efficiency increases to 57.7% Payback period < 2 years Electricity Savings per Year: $123,273 (77%)

12 Reduced bulk power & cooling Impact of Rightsizing Over half the power and cooling losses in a data center are fixed and do not vary with the IT load (the efficiency degrades as the load declines) Oversizing is therefore a primary contributor to inefficiency Virtualization and server power management will make this problem worse, as power and cooling are sized to peak IT loads that are not typical New power and cooling devices that can scale in capacity and/or be managed to a zero power state, reducing the fixed losses

13 Low Density Row Cooling for Heat Removal 30kW per Rack No heat escapes from hot aisle

14 Reduced bulk power & cooling Impact of Rightsizing Capital expense, electricity, and maintenance costs are eliminated for infrastructure that is never deployed

15 In-Row Cooling Cooling systems are placed within IT rows instead of at the room level Inherently higher power density capability than room designs Fan power is reduced by 35% Needless dehumidification / rehumidification is eliminated (saving millions of gallons of water per year per MW) Need for high-bay areas and raised floors are reduced or eliminated (particularly for small installations) Cooling capacity can follow IT loads that move due to Virtualization / server power management

16 High Density Cooling With Rack Air Containment Designed to cool individual high density rack, with or without redundancy

17 High Burden on Cooling Distribution Close-coupled Cooling Hot-aisle air enters from rear preventing mixing Cold air is supplied to the cold aisle Heat captured and rejected to chilled water InRow air conditioner Can operate on hard floor or raised floor 63% of users surveyed expect to be using in rack or in row cooling in the next two years Data Center Polling Results: Power and Cooling, Gartner Research, Feb 2, 2007

18 High Burden on Cooling Distribution Air Handler + Humidifier Loss Comparison 160% % Loss 140% 120% 100% 80% 60% 40% Air handler & humidifier loss exceeds IT load in this region Typical case room cooling 0.92 SHR Improved architecture row cooling 1.0 SHR 20% 0% 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% % IT Load

19 Need for Real-time Visibility Stranded or unusable power and cooling capacity is often created within data centers by unmanaged change Virtualization and server power management will make this problem worse, as power and cooling are sized to peak IT loads that are not typical Capacity management for physical infrastructure is critical to dynamic and virtualized environments

20 Room Cooling Architecture For Data Center

21 Need for Real-time Visibility Types of Threats Power & Cooling Issues Humidity Levels Liquid Leaks Smoke Fire Unauthorized Human Interference

22 Increased Density Raised Floor Room Cooling with Hot Aisle / Cold Aisle Arrangement 5kW per rack The 1.2m cold aisle cannot deliver enough cold air to cool the racks
