Computer Power Management for Enterprises Mike Walker, Beacon Consultants :  Computer Power Management for Enterprises Mike Walker, Beacon Consultants A Practical Guide for Saving up to $100 per PC Annually Outline:  Outline History: Estimated Energy Use of Computers and Monitors (1998 – 2006) ENERGY STAR: Your Solution for Minimizing Computer Electricity Use Computer Power Management VISTA May Make CPM Easier to Implement How to Move Forward in Your Organization Estimated Energy Use of Computers and Monitors (1998 – 2006):  Estimated Energy Use of Computers and Monitors (1998 – 2006) Computer Wattage Now Exceeds Monitor Power:  Computer Wattage Now Exceeds Monitor Power …And the Stock is Large:  …And the Stock is Large PM Utilization: High for Monitors, Low for Computers :  PM Utilization: High for Monitors, Low for Computers Energy Use of Monitors:  Energy Use of Monitors Energy Use of Computers:  Energy Use of Computers What Would 50% CPM Accomplish?:  What Would 50% CPM Accomplish? Electricity to light 8 million homes Reduce 6 million tons of CO2 Remove 1 million cars from the road ENERGY STAR: Your Solution for Minimizing Computer Electricity Use:  ENERGY STAR: Your Solution for Minimizing Computer Electricity Use Slide11:  ENERGY STAR is Your Tool for Reducing Computer Power Use zzzzzzzz… Computer Power Management:  Computer Power Management What is Power Management?:  What is Power Management? Monitor power management (MPM) places active monitors into a low power sleep mode after a period of inactivity System standby and hibernate features place the computer itself (CPU, hard drive, etc.) into a low power sleep mode What is Power Management?:  What is Power Management? Built into Windows 95,98, ME, 2000, XP and now Vista Settings simply need to be activated Why Power Management?:  Why Power Management? Use less electricity Half of energy used to power PCs is wasted Reduce peak load demand charges Some utilities charge up to $200 per kW per year, many charge $150/year Roughly every 180 PCs or monitors power managed saves 1 kW of peak demand Reducing cooling loads Typical office bldg with internal heat load and moderately efficient system saves an additional 15% In southern climates savings can be 30% or more Computer Power Management (CPM):  Computer Power Management (CPM) Original goal of CPM: maximize laptop battery life Increasingly deployed to save electricity on desktops (on AC power) -- can save up to $50 per computer annually Modern CPM shuts down critical system components -- CPU, PCI bus, fans, et al; Most PCs currently use S3/S4 for sleep, and S5 is sometimes used to save power CPM’s ROI:  CPM’s ROI CPM activation in networked environments is not as straightforward as MPM Care must be taken to ensure that sleeping computers do not interfere with the distribution of administrative software updates Older software applications and some peripheral devices may not conform to the latest ACPI standards, and should be tested for compatibility with CPM Still, given the savings potential, CPM offers a tremendous ROI An org with 6000 PCs can expect to reap 3 year savings in excess of $1 million, with costs typically in the low thousands CPM: Where it works best:  CPM: Where it works best Pentium IV (or newer) processors Windows 2000 or XP Regular administrative software updates are 'pulled' by clients from the network, or Wake on LAN features are available to wake up client machines to receive administrative updates Energy savings (up to $50 per PC annually) are compelling enough that organizations are adopting CPM Various Approaches to CPM are Working:  Various Approaches to CPM are Working Software Tools:  Software Tools PolicyMaker Centrally control MPM and CPM on PCs using group policies www.desktopstandard.com Surveyor Network Energy Manager Measures energy consumed by network Manages power settings of PCs and monitors www.verdiem.com NightWatchmanTM Shuts down computers and monitors when not in use www.1e.com/SoftwareProducts/NightWatchman/Index.aspx EZ GPO Group policy object solution for MPM and CPM Download for free at www.energystar.gov/powermanagement Apple’s Mac OS X 10.4 (Tiger) Server Centrally control MPM and CPM on Macs using built in policy manager www.apple.com/server/macosx Apple’s Remote Desktop 2 Centrally control MPM and CPM on Macs www.apple.com/pr/library/2004/jun/21ard.html VISTA May Make CPM Easier to Implement and Use:  VISTA May Make CPM Easier to Implement and Use Windows Vista:  Windows Vista Microsoft is extending Windows power management features in Vista. Anticipated improvements include… Smarter 'hybrid sleep' will be the default when the power button is turned off Vista includes tools called Group Policy Objects that IT administrators can use to easily control CPM. These did not exist in XP. EPA’s GPO tool was a way to get around this limitation. Vista will be shipped with MPM and CPM defaulted Software applications will no longer be allowed to veto sleep How to Move Forward in Your Organization:  How to Move Forward in Your Organization Suggested Tasks:  Suggested Tasks Review behaviors Shut off at night Sleep enabled for monitors and computers Calculate savings Energy managers Senior staff Contact EPA for help if needed Engage your IT department Central management of CPM Need to access computers at night How to Centrally Manage CPM:  How to Centrally Manage CPM Use in house solutions 3rd party software EPA’s EZ GPO tool activates system standby (S3/S4) Vista supports central management of CPM related settings Desktop Standard’s PolicyMaker (also MS) activates S3/S4 Verdiem’s PC Surveyor manages PM features and implements time-based power profiles 1E’s NightWatchman remotely turns off computers (S5); requires enabled WOL Access to Sleeping Computers:  Access to Sleeping Computers OBSTACLE: Many IT managers perceive need for continuous availability SOLUTION: Sites can wait for maintenance events (patching, backup, etc) to occur on wake up (GE does this) Wake-on-LAN (WOL) can be implemented Scheduled wake ups can provide needed availability Wake-on-LAN: What is it?:  Wake-on-LAN: What is it? WOL is a means to wake networked machines Originally designed to allow for remote administration of client PCs NIC signals a PME to wake the machine when it receives network traffic The NIC can be configured to look for specific types of network traffic (ie 'The Magic Packet') Various configuration and network topology is required to make this work Technical Assistance:  Technical Assistance We help develop energy savings estimates We help IT administrators quickly identify the easiest, lowest risk paths to power management A brief conference call with your IT administrator(s) is usually all it takes to get started Summary:  Summary Implementing MPM and CPM can save $50 per PC annually Many organizations are already saving IT managers are overcoming obstacles to CPM Growing number of large-scale implementations We can help you develop your implementation options Contact Information:  Contact Information Additional information at: www.energystar.gov/powermanagement Contacts: Mike Walker, Beacon Consultants (EPA Technical Support Contractor): 617-921-8445, mwalker@beaconconsultants.com Steve Ryan, US EPA Energy Star Program Manager: 202-564-1254, Ryan.Steven@epamail.epa.gov
