Where the Power Goes Platform View
Power Consumption Review
  • Remaining 50 DC power consumed in Servers
  • 50 of which is internal AC Conversion
    Cooling
  • 30 is the processors themselves (but 50
    leakage)

System average based on Intel Dual Processor
1U and 2U reference Server Board Power Budgets.
Actual end user power profile may vary depending
on manufacturer and configuration.
6
Power Reduction Facility View
Power Consumption Review
  • Critical that Server and building industry come
    together for operational expense reductions
  • Fast T-rise prohibits sensors alone
  • Early warning/feedback from servers key

7
Power Reduction Platform View
Power Consumption Review
  • Server manufacturers and PS/VRM vendors together
  • Determine optimum efficiency points
  • Investing in new technologies for efficiency

8
Power Reduction Processor View
Power Consumption Review
  • Intel is bringing dramatic reductions starting
    this year
  • Leakage fraction last years on new 2005 silicon
    process
  • Core power and leakage reductions continue
    unabated

These values are listed by Intel as a
convenience to Intel's general customer base, but

Datacenter Modular Power Issues
12
Todays Datacenter Profile
  • While Datacenters (DC) vary considerably
  • Almost all utilize air for heat removal
  • Most new builds are in the 90-135 W/sq.ft.
  • Approximately 6-10 kW/rack
  • Most are power-out limited vs. power-in limited
  • Some rare ones in the 500 W/sq.ft. (ROI?)
  • Are large capital 10 year investments

13
Issue Rack System Power Profile
1082 W AC total
894 W AC total
  • 2U system (average config)
  • Unrestricted Rack21.6KW (20)
  • 40 total Processors
  • 721W/sq ft _at_ 30sq ft/rack
  • 6 sys at 90W/sq ft, 12 Processors
  • 1U system (average config)
  • Unrestricted Rack 35.7KW (40)
  • 80 total Processors
  • 1192W/sq ft _at_ 30sq ft/rack
  • 7 sys at 90W/sq ft, 14 Processors

14
Issue Power doesnt track Utilization
A day in Exchange Workload
Processor utilization indicates how busy a server
is.
System power continues to be high during low
processor utilization.
DP-500W .NET Web Server
Average Power 170 Watt despite big variation in
processor utilization
15
Issue Rack Utilization
Nameplatepower
  • Power consumption varies widely and not well
    understood by End Users
  • Wide variance based on configuration and
    utilization
  • Full Nameplate typically leaves rack space,
    power, and cooling headroom under many
    configurationslost ROI
  • Simple nameplate de-rating under-predicts full
    configuration consumption, tripped breakers and
    downtime result!

Rackutilization gap

Need reliable industry methodology to close the
rack utilization gap
16
Intel Power Utilities
  • Demand Based Switching
  • Power Calculator
  • Power Monitor

Intel Power Utilities - Summary
Intel Power Utilities
  • Demand Based Switching reduces active power

18
Solution Demand Based Switching
Server system power without DBS
processor utilization
Server system power with DBS
AC power as of max AC power
Assumptions All components except processor
consume fixed amount of power
Estimated power profile for the hypothetical
example
DBS gives application the power when it is needed
William Hammond
19
Demand Based Switching (DBS)
Intel Power Utilities
  • Utilizes Enhanced Intel SpeedStep Technology
  • Dynamically reduces processor speed/power based
    on demand
  • Reduces system power up to 24 for typical CPU
    utilizations

Lower operating costs with DBS
System based on Intel Server Board SE7520JR2
board, 4 GB DDR2-400 memory. 24 power savings
at approximately 46 CPU utilization with DBS OFF
running WeBench. See backup for full system
configuration. Customer results may vary
depending on hardware and software configuration.
20
DBS - System Power Benefits
Intel Power Utilities
You can reduce power and save operating costs
with DBS
Customer results may vary depending on hardware
and software configuration.

Intel Power Utilities
Intel Power Utilities
  • Power Monitor
  • Utility measures actual power consumption
  • Real time data collection instead of worst case
    assumptions
  • Power Calculator
  • Utility estimates worst case system power
  • Uses actual system components versus nameplate
    (full configuration)

Reliable, standardized approach to help optimize
rack utilization

DC Power Futures Attacking the OpEx problem
27
Operational Expense - Problem
DC OpEx futures
  • Business needs not aligned with power consumption
    neither platform nor DC
  • Little capability to minimize OpEx
  • Little capability to fully maximize CapEx
  • Pre-defined Service Level Agreements (SLA) are
    measured historically

Power Utilities is part of the solution
28
Operational Expense - Solutions
DC OpEx futures
  • Web services type interaction is the future for
    both platform and traditional facilities
  • Service Oriented Enterprise control
  • Service Oriented Infrastructure communication
  • Service Oriented Architecture compute/facility
  • All assets will report capabilities via CIMXML
  • CoD/grid deployments used to match to SLA
  • Highest business needs will get priority systems
  • Lower business needs will be OpEx optimized

Power Utilities will grow with your DC
29
Future Directions
DC OpEx futures
  • Datacenter as a full feedback system
  • Cooling supplied as needed, to the systems req
  • Goes after the 50 utility cooling costs
  • Model ROI/TCO for multiple traditional DC
    capability
  • Open ballroom with minimum racks
  • 1 AHU 3 Racks, 3x3 active grid, 210 Servers
  • Rack utilization matched to current thermal
    planning
  • 1 AHU 22 racks, 1 active / 2 inactive tiles,
    210 Servers
  • Monitor/Enable new cooling models
  • Cold plate technologies enable dense server
    configs
  • Emergent DCs enabling spot solutions (non-air)
  • ROI models for super dense DCs
