This document outlines Saint Louis University's strategy for improving power management of IT equipment to reduce costs and environmental impact. Key points include: 1) SLU aims to standardize power-optimized default settings on all managed PCs and laptops through automated software and establish policies around exceptions and existing devices. 2) Potential savings are estimated from generational improvements in computer hardware and adopting lower-power modes like sleep versus screensavers. 3) The strategy also involves consolidating servers, enabling energy-efficient settings on printers and other electronics, and establishing institutional goals around student computer energy use.

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

3. 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

4. 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

6. SLU Personal Computers: 5764 Managed PCs by Summer 2007 No Mac Management at this time

7. Potential Savings: Generational Changes in Power Management New Laptops New Desktops 2005 Desktops Assumptions

9. 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
