1. Green IT Focus: Server Virtualization

2. Why Server Virtualization Matters
Reduces number of physical servers and total cost of ownership
Decreases Data Center space and cooling requirements
Saves an estimated 7000kWh of electricity annually per server, or about $700 in energy costs
Eliminates approximately 4 tons of CO2 for each server virtualized (equivalent to removing 1.5 cars from highway)

3. Project Goals Initial proposal Increased performance and scalability
Improved redundancy and disaster recovery
Reduced total cost of ownership
Simplified backups
Matched development/test/production platforms
Added Green IT significant benefits
Reduced energy usage and physical footprint
Less heat generated, less cooling required

4. Timeline and Key Milestones
February Initial proposal developed
August virtual servers deployed in
main cluster
October virtual servers in main cluster, total of 102 virtual servers in production

5. Phase I Implementation
Before
After

6. Before After 30+ physical servers in 5 racks, greater than 10kW
79 virtual servers in 1 rack, less than 3kW
2 plus weeks to provision new server
Less than 10 minutes to provision new server
Complex configurations very time consuming
Complex configurations much easier
Some redundant hardware
Much improved redundancy in components & data paths, load balancing

7. Green Results Current estimated net power savings: 23.4kW
Fewer physical servers in the Data Center results in less heat generated, less cooling costs, and less physical space required
Decreased costs for server related deliveries and disposal of packing materials & e-waste
Power utilities provide incentives based on net reduction in kW/hours to help offset capital investment

8. Next Steps Virtualized desktops
Blade servers for further power savings
Dynamic Power Management (ability to power off idle hosts)
Warm-site recovery
Virtual server hosting service for campus units
