Presentation Transcript

  1. Green IT Presented by: Lauri Petersen Great River Energy

  2. Great River EnergyCompany Profile G & T Cooperative • 2,800 MW generation • 4,500 miles of transmission line • 900 employees • 28 distribution member cooperatives

  3. GRE Headquarters • LEED Platinum Certified by the U.S. Green Building Council in 2008 • LEED = Leadership in Energy Efficiency Design

  4. IT Profile • Information, Infrastructure, Project, and Support Services • 62 employees • 2 enterprise and 3 local data centers • 300+ servers (> 50% virtualized) • 80+ business applications • Integrated IP network for corporate, operations, and remote sites

  5. Background • New headquarters in Maple Grove, MN (3/09) • Corporate data center move • Local data center move • Aging infrastructure (and architecture) • Critical dependencies • No “Green IT” recipe • LEED Certification

  6. Guiding Principles • “Green” data center and workplace • Incremental improvement • Centralized/Distributed approach • Reduce/Reuse/Recycle

  7. Industry Definition Green IT: optimal use of information and communication technology for managing the environmental sustainability of enterprise operations and the supply chain, as well as that of its products, services and resources throughout their lifecycles. Source: Gartner

  8. In North America, most of the interest in Green IT is economic rather than environmental. • More than 60% of data centers will face space and energy constraints in the next 18 months (July 09) • Server virtualization is the main mechanism through which data centers and IT managers are lowering their data center energy costs

  9. Green IT Initiatives/Opportunities

  10. Existing Servers – 08/21/09 • Physical Servers= 134 Windows = 87 Linux/Unix = 47 • Virtual Servers = 202 Windows = 160 Linux/Unix = 42 • Total = 336 servers • % Virtual = 60%

  11. Existing VM Capacity • Standard vHW: 1 vCPU, 1GB vRAM, 20GB vHD • Total Capacity = 240 VMs • Used = 202 VMs (As of Aug. 21, 2009) • Available = 38 VMs • Cost per VM in ER = ~ $3,850 • Cost per VM in MG = ~ $3,528

  12. Measure • Measure to show results • Obtain a baseline of “current state” • Measure changes and/or improvements to support investment(s) in Green IT

  13. Data Center Design Considerations • Hot aisle / cold aisle • Blanking panels • Proper vent placement • Cold aisle containment • Raise temp to 75⁰
