IT Power Management Strategy

1
IT Power Management Strategy Business Case

• Enterprise Architecture
• Information Technology Services
• Saint Louis University

2
Why Look at Power Issues Now?

• Proactive financial planning the AmerenIP
  Illinois rate change story, future energy costs
  
• Policy opportunity to define the default power
  configuration expectations of electronic devices
  
  
• Environmental stewardship and the University
  Mission
  
• Scheduled PC replacement, with HD data cleansing,
  creates opportunity to phase in new lower-power
  technology
  
• Disposal Initiative already proposed for
  responsible electronics recycling and disposal

Drivers for Computer Power Management Strategy

• Billiken InfoShield completion all PCs could now
  be power-optimized by managed software settings
  
• Generational improvements computer hardware
  (Energy Star advancement)
  
• Laptop interest increasing, especially faculty
  and students
  
• Datacenter power load growth, partly from
  non-enterprise departmental servers
  
• Peripherals and electronics default settings
  offer Energy Star options
  
• CRT-based displays seldom purchased now

Computer Hardware Generational improvements

• Personal Computers could be set to use 70 less
  energy than current (2002 IT Power Costs
  spreadsheet)
  
• CPUs from Intel and AMD now emphasize power
  manageability (if configured ! )
  
• CPUs sit idle much of the time new processors
  can enter low power state
  
• Sleep instead of screensavers savings
• Managed, automated night shutdown
• Potential HVAC savings from heat reduction

5
Laptops in Energy Strategy?

• Lowest power requirements, comparable computing
  power for most users
  
• Built-in LCD monitor
• Battery backup for brown-outs and outages
• SLU wireless investments promote productive
  mobility
  
• Discourage Monitors! Power savings ,
  costs if external monitors are used

What Will It Take to Do It?

• Immediate deployment in 800 shared use PCs
  beginning in May
  
• IT rollouts of power-optimized new PCs when
  purchased
  
• Limited, clearly defined exception request
  policy for research computers, special needs
  
• Community decision on applying power management
  to existing SLU-owned PCs
  
• Adopt specific institutional PC-power goals
• Consider student computers energy use

10
Datacenter Power Strategies Opportunities

• IT exploring fewer, but more powerful physical
  servers hosting multiple virtual servers for
  the future
  
• Server high efficiency power supplies
• High-efficiency cooling enclosures
• Policy needed on criteria for housing
  non-enterprise servers in Datacenters (unmanaged
  power growth)

11
Printers, Copiers, Electronics

• Encourage shared printers/copiers over personal
  printers
  
• Enable Energy Star default settings as SLU
  installation standard
  
• Expand smart shutdown management tools, such as
  in classroom presentation systems
