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)

Active Energy Manager will

Provide:

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 - Increased Density

Inefficient 1U servers

10KW rack holds 23 1Us (427W)

Power-efficient BladeCenter servers

10KW rack holds 28 blades (270W)

Power-efficient BladeCenter with Active Energy Manager

power virtualization

Improve performance/watt

by up to 90%

10KW rack holds 44 blades (270W)


3636

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, each with wasted overhead
