  1. Green IT

  2. Overview Over the last decade, the University has implemented a number of green technologies • Change computing policies: • More energy efficient hardware • Virtualization • Thin and thick Clients • Overhauled printing practices in sites

  3. Basic Energy Consumption Facts • When not in use, Computers 4 modes • Do nothing, run normally (almost never used) • Standby, turns monitor off • HD may or may not spin down, some other controls • Sleep, turns all off but network • Turn off entirely

  4. Energy Usage: Computers • Standard desktop used 2000 hours per year and Standby uses approx $110 in electricity • 170W in use, 85W standby, 10W Sleep • All savings from standby -> Monitor. • CPU uses same in standby as in use! • Same machine using sleep mode: $50 per year, saves $60 or 55%. • Turning off when not in use saves and additional $6 (could use hibernate)

  5. Energy Usage: Computers • Laptops use 30-50W overall, far more efficient. • When using hibernate usage to zero, • consumption varies with usage level • Stepping mode, brightness, etc. • iMacs, use about 80W awake, 40-50W sleep or standby (same), about $60 a year. • MacPros same or more usage than desktop depending on configuration.

  6. Energy Usage: Computers • Sunray with 20” monitor: • $14 per year • Even when considering back-end servers, they save 75% of a desktop using standby • Save as much as $75 per year per unit • Similar with all-in ones or box units. • Nettop: • 30W Running/Standby+ Monitor • Approx $40/yr. using standby • Approx $20/yr. using sleep

  7. Energy Usage: Monitors • GW 24”, 100W + 5W $30 yr • 20” LCD, 70 W + 3W $20 yr. • 20-28” Low power (fleuro OR LED) 20-25W + 1W $6 yr. • Cost of new monitor $100-180, saves up to $24 yr.

  8. Energy Usage: Other • Appliances, Refrigerator • Lighting • Comparisons – see the web

  9. Computing SItes Major transition over past five years • SunRays • Over 45% of site machines now SunRays • Three terminal servers host 77 machines • Christiana, Dickinson, Harrington Sites • Kiosks in Trabant and Perkins • iMacs in sites • More efficient • Flexible, Win or Mac OS • Use of sleep mode transitioned from Standby or turned off overnight

  10. Virtualization: Servers • 2008 CS&S Server Renovation • Initially 18 physical servers • 10 Virtualized (8 site plus 2 core/admin) • Two virtual hosts • Net savings per machine: $160, and this was a low ratio. $1600/yr. in electricity • Other costs as well: Cooling, space, etc. • Ended up using excess capacity for testing • Ratio of 8:1 easily obtainable -> $180 per machine in electricity alone.

  11. Virtualization: KACE • 2010 CS&S lead KACE management appliances • Cooperative alliance, cost sharing • Thirteen campus units and growing • Ten servers requested, more to be added • All running on single virtual host • Second virtual host to add redundancy • Dramatic power savings, approx. $1600/yr.

  12. Printing • One of UD’s Largest Success stories • 2001-2002 6.1 million sheets printed • Up to 80% wasted -> Proofs/Never picked up • 2002 implemented PrintLess Campaign • Posters and web pages • Charging for printing • Usage down 80-90% • Below 1 million sheets ever since • All sites use recycled paper • All toner cartridges recycled. • Transition to Webfoms

  13. eWaste • Five years ago: • Pay to haul away hazardous waste per weight • Central receiving • Collects • Offers for redistribution/parts for 30 days • Transports monthly to DSWA • DWSA processes at no cost to UD.

  14. Measurement • Kill-A-Watt EZ4460 • $25 at Amazon.com • Plug it in in-line • Set utility rate ($0.11 approx here) • Collects data • Instantaneous readout • Running average • Yearly estimate • Lots of stats available on the web

  15. Energy Urban Legends • Power transformers draw significant power? • Cell Phones and chargers • Laptops • Parasitic Transformers • Reality: Cell phone charger • plugged in $0.85 yr. • Charging and plugged in $1.65 yr. • Remainder near zero when not in use.

  16. Best Practices • Sleep Mode (downside: no terminal in) • Thin or Thick Clients • Virtualize as possible • General conservation (lighting appliances) • Discourage Printing • Charging works • Electronic Submission • Kill-A-Watt

  17. Mainstream Nettop Units • Standard is 2GB mem + 320GB HD • Acer Veriton, D525+ION2 $475 (Amazon) • Lenovo Ideacenter Q150, D510 + ION, 2GB $500ish • Asus Eebox, D525 +ION2+ Slot DVD $519 (Amazon) • Dell Opti 160, Generation 1 • Atom 330, 4GB, • 64GB slow SSD, • slow graphics • List $917, UD $754

  18. Demo: Atom 525 JetwayUnit • Cost • Available w/o HD or memory $209 • 4GB DDR3 laptop memory $58 • 64 GB SSD $100 • Total cost: $367 • Features • Ion2 Graphics, makes it usable, HD Video • HDMI + DVI, capable of dual monitor • SDHC • Wireless N + Gigabit • 5 USB + eSATA • Not recommended for distribution, No support
