IBM Power & Cooling Usage
The processor power growth is the largest single contributor but there are many
other areas. The more you pack into a server the more power it needs.

How data center cooling works?
The key requirement is to maintain rack inlet temperatures within manufacturer’s specifications

IBM Active Energy Manager
> Measure/Trend Power Consumption (Phase 1)
 Determine the power (watts) is being consumed now
 Why assume label power?
 Power meter (internal) or PDU with watt meter (external)
> Cap or Allocate Power Correctly (Phase 2)
 Power consumed is a function of the HW options, OS, Apps and App
footprint application and the application data footprint
 Allocate power based on past history using power measurements:
−to match the need of each server
−to match the P/T limits of the data center
> Reduce power consumed (Phase 3)
 CPUs can reduce power in periods of low utilization
 Save power costs
Three Fundamentals of Power Management
> A view of power consumption across the data center (units of hours, weeks,
months) using your applications and workloads
> Reducing your power/thermal requirements (saving infrastructure costs –
ex. HVAC, UPS, generators)
> Reducing power consumption during periods of low utilization (saving
power costs – ex. utility company)

IBM Active Energy Manager Overview
> Enables management of actual
power consumption and resulting
thermal loads
> Intelligence to control and
manage datacenter server power
utilization
 Hardware, embedded
management logic
 Sensors and alerts exist to
warn the user if limiting power
to this server is affecting
performance
> More accurate data center
planning:
 Actual power draw instead of
conservative “label/spec
power” estimates

IBM Active Energy Manager - Allocated Power
> Rack density is based on power consumption estimates, which typically leads to
a 20 percent over allocation of power
Result is multiple servers,
