Green IT How to save money and help

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

Why Green IT? • • Save Money Save energy Save in cooling Reduce long term hardware spend Reduce carbon emissions Save space in server room and desktop Avoid infrastructure upgrades

Who can do Green IT? • Anyone in control of a computer/s and related hardware • System Administrators • Equipment manufacturers • Computer assemblers • IT sales personnel • IT project contract authors • Project Managers

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

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

Compare same Laptop with Power Management Time Performance (watts) Power Saving on (watts) Active Operations 45 44 5 minutes idle 31 30 15 minutes idle 31 20 30 minutes idle 31 1. 5 Average 34. 5 23. 9 Celeron 1. 8 GHz laptop with Vista Basic. 44% power saving using settings only.

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 • ~ $93 k in hardware

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

Blade Computing • • • Cheaper than individual servers in bulk Redundancies built in Saves space Can be used for virtual servers and /or support thin clients E. g. 8 blades with 2 x quad processors == 64 CPU’s 8 blade enclosure 264 mm tall (6 RU) Dual processor blade with 2 disks

V Motion

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

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

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

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

~ 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

Thin Client Example • Run 26 -42 thin clients per 4 CPU server • Full multimedia thin clients available • Can use wireless, Ethernet, modem or 3 G card for connection • Can also be used for VOIP telephony • Consume ~ 11 watts each • No replacement cycle • ~ 25 kb/s average bandwidth

PC versus Thin Client power use

Energy Star Rating 4. 0 Computer Idle Sleep Standby Desktop < 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

Power Management from Desktop

Computer Sleep States S 3 & S 4 • When S 3 or S 4 level sleep state is enabled in BIOS the computer power consumption goes down to a few Watts • S 1 – Flush caches and stop processor • S 2 – S 1 + power down processor • S 3 – Keep memory powered and power off everything else possible. Quick to resume time • S 4 – Hibernate, memory to hard disk. Power failure safe. Slower resume time

BIOS Checklist ü Advanced Configuration and Power Interface (ACPI) : Enabled ü Smart Fan : Enabled ü Suspend Mode : S 3 ü Speed Step / Cool n quiet : Enabled ü Motherboard defaults are getting better (needed for Energy Stars)

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

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

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

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

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