  • 5. Background on Green IT
  • 6. Green IT
    • Being “green” means to minimize negative environmental impacts and maximize positive impacts
    • IT is a key stakeholder for a variety of reasons
      • Energy usage (our focus today)
      • E-Waste
      • IT services that advance the organization
    • “Green IT” is becoming a buzzword to sell products and services
      • Gartner terms it “greenwashing”
      • A lot of conflicting messages and bogus claims
  • 7. Green IT and Energy Efficiency Cost Savings
    • Brand
    • Reputation
    • Customers
    • Investors
    • Employees
    Protecting the Environment Regulatory Compliance Intense Pressure
  • 8. Prioritization, Command & Control
  • 9. Supporting the Organization’s Green Strategy
    • The environment and being “green” is an organizational issue
      • Management of ecological impacts is a necessary condition
      • Green needs to support the organization’s goal(s)
      • The Board establishes the goal(s) for the organization
      • The Board hires and directs management
      • This Board-Management linkage is true organizational governance
      • Management must take the appropriate steps to
        • Move towards the goal (create value)
        • Protect the goal (protect value)
        • Corporate Social Responsibility (CSR) Programs
    • IT is part of the larger organizational system
      • IT’s green efforts need the proper context
  • 10. The Green IT Process
    • Manage Green IT as a process because:
      • Inputs and Outputs
      • Sub-processes
      • Roles and responsibilities
        • Process Owner
        • Process Manager
      • Metrics and reporting
      • Process integration is vital
    • “ The goal of Green IT is to support the green objectives of the organization as defined by the Board and/or a Corporate Social Responsibility management group.”
  • 11. Improvement Opportunities
  • 12. Virtualization
    • Reduce the number of systems consuming power
    • Improve average utilization
    • Servers
      • Average 6-10% utilization
      • Reduction could be N+1 or 2(N+1) depending on fault tolerance
    • Clients
      • Enable use of thin clients with lower power requirements
      • How many are left on 24x7 today?
    • Improved management capabilities across the board
    • Note – high-performance high-density blade servers can create challenges as well so plan carefully
  • 13. Cloud Computing and SaaS
    • Why host at all?
    • Providers are building mega data centers
    • Cloud Computing
      • Move the hardware into the Internet to a provider
      • Decouples hardware from service
      • Key feature – massive scalability
    • Software as a Service
      • Technically different from cloud computing
      • SaaS could be considered Cloud Computing if massively scalable
    • Moves emphasis to network management
      • Need high-availability, adequate performance, security, etc.
    • Due diligence is critical to manage risks
      • What if the provider goes out of business?
      • What do they do for security?
      • What do they do for fault tolerance? … etc., etc.
  • 14. Power Management Software
    • Newer systems have more features
      • Servers, desktops, printers, copiers, etc.
    • Vendors have made a lot of headway
      • Faster power ups
      • Phased power up of resources
    • Appropriate for user driven systems
      • Servers exhibiting prime time demand
      • PC’s only used during business hours
    • Be sure to test settings before deploying
    • Ensure preproduction and production platforms match!
  • 15. Reductions in Printing
    • Printers in general consume power
    • Personal printers can be very inefficient
      • Personal laser printer energy bills can exceed toner costs
      • Often lack extensive power management features
      • Are often left on 24x7
    • Paper causes a three dimensional challenge
      • Cutting trees reduces CO2 absorption
      • Considerable power is used to create it
      • Power is used to print it
      • A considerable amount of it results in waste
        • Recycled to some extent
        • Landfill
    • Opportunities for
      • Electronic forms and workflow
      • Online reports
      • Imaging
      • Balance is needed – impacts of printing vs. impacts of escalating storage demands
  • 16. Telecommuting & Travel Reduction
    • Enabling employees to productively and securely work from home
      • High-speed networking
      • Security tools and training
      • Enabling applications for remote access
        • Web-based, Citrix, etc.
    • Facilitating remote collaboration to reduce travel
      • Online presentations / meetings
      • Remote collaboration tools
      • Potential scope: employees, vendors, customers
  • 17. Optimize Application/Service Design
    • Design with services in mind – not just applications
      • Ongoing operating costs can be far higher that purchase/implementation costs
    • Requirements need to factor in Green IT standards
    • Staff needs appropriate on-going training
    • Investigate / implement
      • Virtual environments
      • Remote users
      • Judicious use of resources vs. requiring 100% of resources 100% of the time (use a tiered capacity utilization models)
      • Power management capabilities
      • Platform as a Service (PaaS)
  • 18. Optimize Data Storage
    • Storage demands are exploding
    • Can’t store everything forever
    • Storage consumes power and generates heat
    • Establish data retention requirements
    • Need an Information Lifecycle Management (ILM) process
    • Need to normalize data designs
    • Utilize compression to reduce space requirements
    • Adopt tiered storage models
      • Online, near-line and offline storage
    • Platform as a Service (PaaS) or other outsourced model
      • Use a service to facilitate storage
  • 19. Optimize Business Processes
    • IT helps functional areas create and protect value
    • Need to enable them to attain green objectives including improving energy efficiency
    • Use Theory of Constraints to understand the goal and the greatest constraint
    • Lean – Philosophy about waste reduction and obtaining value
      • Wasted time, wasted materials, over design -- Non-value add
    • Six Sigma – Attention and tools to identify defects and drive down the costs of rework
    • Lean Six Sigma (LSS) - address defects, time wasted and increase overall speed while reducing cost
    • IT is a tool to enable the business in pursuit of the above
  • 20. Examples
    • Improved scheduling reducing inter-facility materials movements (Fuel savings)
    • Improved demand planning reducing expedited shipments (Fuel savings)
    • Online collaboration tools reduces travel related to the design of a new product or service
    • Use or portable terminals to reduce inventory related paper forms such as requests, transfers, etc.
    • Reduction in paperwork by implementing forms for paid time off, suggestions, service requests, etc.
    • Move to electronic invoices to customers and online customer service
    • Charge customers for power usage in the data center to drive accountability and cost:benefit
  • 21. Continuous Improvement
    • The first step is only the beginning of a journey
    • Needs will change as technologies and the world changes
    • Leverage metrics where possible to track status
    • Conduct quarterly reviews of progress
    • Maintain the tone from the top
    • Formally schedule reviews to assess the current state and look for new opportunities
  • 22. New Pocket Guide – The Governance of Green IT
