1 Green IT How to save money and help the environment with knowledge Presented By Matthew Bulat M.Eng.Tech MCSE MCDBA

2 Why Green IT? Save MoneySave Money Save energySave energy Save in coolingSave in cooling Reduce long term hardware spendReduce long term hardware spend Reduce carbon emissionsReduce carbon emissions Save space in server room and desktopSave space in server room and desktop Avoid infrastructure upgradesAvoid infrastructure upgrades

3 Who can do Green IT? Anyone in control of a computer/s and related hardwareAnyone in control of a computer/s and related hardware System AdministratorsSystem Administrators Equipment manufacturersEquipment manufacturers Computer assemblersComputer assemblers IT sales personnelIT sales personnel IT project contract authorsIT project contract authors Project ManagersProject Managers

4 Measure consumption to find out how much you save with efficiency changes Single Power point meter ~ $40Building power meter $100, 3 phase $150

5 Can I apply Green IT now? YESYES Turn on Screen and Hard disk power managementTurn on Screen and Hard disk power management Turn on Sleep and / or Hibernation managementTurn on Sleep and / or Hibernation management Shutdown computers at then end of each dayShutdown computers at then end of each day This saves approximately 60% on powerThis saves approximately 60% on power

6 Compare same Laptop with Power Management Time Performance (watts) Power Saving on (watts) Active Operations minutes idle minutes idle minutes idle Average Celeron 1.8 GHz laptop with Vista Basic. 44% power saving using settings only.

7 Virtualization possibilities 8 CPU server 48 GB RAM 40 Virtual Machines 700 Watts SAN with 7.5 TB 840 Watts 220 mm rack space 1540 Watts total ~ $93k in hardware

8 SAN holds shared virtual machines Fibre channel card in each server which can work in redundant pairs Full bandwidth fibre switch 400 MB/s Models up to 900 TB Can be extended by adding Disk Enclosures without powering off

13 Distributed Resource Scheduler Move virtual machines and shut off physical server when resource needs are low Automatically save 40% more power by having server switch off at night and weekends

14 Green Choices Turn on Power ManagementTurn on Power Management Set screensavers to NoneSet screensavers to None Buy Energy Star rated computersBuy Energy Star rated computers Use laptops instead of desktops as they typically use less powerUse laptops instead of desktops as they typically use less power Turn off peripherals when not in useTurn off peripherals when not in use Turn off power at power point to stop phantom / standby loadsTurn off power at power point to stop phantom / standby loads Close unused applicationsClose unused applications Turn off monitor when not in useTurn off monitor when not in use Measure your power consumptionMeasure your power consumption

15 Peripherals Control USB controlled power board (~$40)USB controlled power board (~$40) When computer turns on USB turns on power pointsWhen computer turns on USB turns on power points This can power monitor, printer, speakers, scanner, external USB storage etc.This can power monitor, printer, speakers, scanner, external USB storage etc. Peripheral power consumption when computer off ZEROPeripheral power consumption when computer off ZERO

16 Power Supplies (80 PLUS) The best power supplies now are up to 88% efficientThe best power supplies now are up to 88% efficient This means less waste heat from computersThis means less waste heat from computers Saving up to 28% PC use of electricitySaving up to 28% PC use of electricity Less maintenance calls related to heat issuesLess maintenance calls related to heat issues Save 30% of related cooling costsSave 30% of related cooling costs Better power factor saves you even moreBetter power factor saves you even more

17 ~ 60% efficient power supply More heat into computer Higher power consumption ~ 80% efficient power supply Less power in Less heat Less cooling needed 85% efficient power supplies available

19 Thin Client Example Run thin clients per 4 CPU server Full multimedia thin clients available Can use wireless, Ethernet, modem or 3G card for connection Can also be used for VOIP telephony Consume ~ 11 watts each No replacement cycle ~ 25 kb/s average bandwidth

20 PC versus Thin Client power use

21 Energy Star Rating 4.0 ComputerIdleSleepStandbyDesktop < 50 Watts < 4 Watts < 2 Watts Notebook < 14 Watts < 1.7 Watts < 1 Watt Component Selection Guidance Power supply with 80% minimum efficiency at 20%, 50% and 100% load Display in sleep mode in 15 minutes or less when idle Processor in sleep mode in 30 minutes to less when idle Network speed reduced from 1 Gbps to 100 Mbps or 10 Mbps when sleeping

22 Power Management from Desktop

23 Computer Sleep States S3 & S4 When S3 or S4 level sleep state is enabled in BIOS the computer power consumption goes down to a few WattsWhen S3 or S4 level sleep state is enabled in BIOS the computer power consumption goes down to a few Watts S1 – Flush caches and stop processorS1 – Flush caches and stop processor S2 – S1 + power down processorS2 – S1 + power down processor S3 – Keep memory powered and power off everything else possible. Quick to resume timeS3 – Keep memory powered and power off everything else possible. Quick to resume time S4 – Hibernate, memory to hard disk. Power failure safe. Slower resume timeS4 – Hibernate, memory to hard disk. Power failure safe. Slower resume time

24 BIOS Checklist Advanced Configuration and Power Interface (ACPI) : Enabled Advanced Configuration and Power Interface (ACPI) : Enabled Smart Fan : Enabled Smart Fan : Enabled Suspend Mode : S3 Suspend Mode : S3 Speed Step / Cool n quiet : Enabled Speed Step / Cool n quiet : Enabled Motherboard defaults are getting better (needed for Energy Stars) Motherboard defaults are getting better (needed for Energy Stars)

25 Managed Power Management Software Can shut down computer as required by group policyCan shut down computer as required by group policy Work can be saved before automated shutdownWork can be saved before automated shutdown Reports on status of all computers and how much power is being savedReports on status of all computers and how much power is being saved Can wake up computer for updates or start of work dayCan wake up computer for updates or start of work day Save ~ $6700 per year for 100 desktopsSave ~ $6700 per year for 100 desktops

26 Storage alternative Network Attached Storage File server Backup + replicate server mySQL database server Web server FTP server Print server Multimedia server 17 watts in operation 6 watts in sleep mode $650 for 1000 GB

27 Cooling Calculations  There is a direct relationship between energy consumption and cooling requirements needed (3 BTU capacity needed for every 1 Watt electrical load)  Choosing efficient servers / desktop PC / notebooks / thin clients reduces the building cooling needs  This saves money in initial capital costs and running costs

28 Other Processors Intel Atom processor uses up to 4 Watts and now is used on small laptops Via Eden processors use from 2.5 to 7 watts and require no fans which is good for embedded or battery power ARM processors are used in PDA’s, mobile phones, media players and sections of consumer electronics

29 Where is IT saving environment now? Electronic banking, electronic receipts, electronic pay slips, Intranets, Wikis, electronic form handling, instead of post, instead of fax, duplex printing, saving us from repetitive tasks, decision support systems, electronic commerce, instant messaging, electronic magazines & newspapers, online services such as , document handling and computer maintenance.Electronic banking, electronic receipts, electronic pay slips, Intranets, Wikis, electronic form handling, instead of post, instead of fax, duplex printing, saving us from repetitive tasks, decision support systems, electronic commerce, instant messaging, electronic magazines & newspapers, online services such as , document handling and computer maintenance.
