“Gartner predicts half of data centers will run out of power by 2008”

— Gartner Conference Headline Computerwire, December 6, 2006


“The greatest impediment to growth in our data centers is caused by power and cooling limitations.”

— CIO, Large Insurance CompanyEMC Briefing Center

Energy Consumption in the Data Center

What makes energy more important now?

How should demand be measured?

Where are the big opportunities to save energy and reduce cost?

4


Energy Demand and Moore’s Law

Moore’s Law: computer performance will roughly double every 18 months

– Driving higher processor and memory performance– Higher performance leads to hotter components that are more

densely packed, consuming more power in less space– Higher power density requires increased cooling power


More IT applications. More data. More servers. More storage. More energy demand.

Measuring Energy Consumption

When provisioning a data center power and cooling, would you…

1. Add up all of the circuits and calculate sum of circuit ratings?

Total current = 100A

2. Calculate the sum of all of the equipment specification sheets?

E.g., total current = 38A

3. Calculate from actual measurements?

E.g., total current = 28A

Typical IT load is significantly less than design capacity.

50A Circuit 50A Circuit

Configuration Workload Duty cycle Battery recharge state

Redundant power feeds Safety ratings

Additional Considerations


Prior to installation you need to understand: Specific equipment configurations Normal and abnormal operating modes

Calculate: Base system power

– System enclosure– Disk enclosures

Component power– Disk drives by speed– Front-end components– Back-end components– Memory modules

Actual power consumption and heat dissipation for:

– Typical load– Maximum load– Special conditions

Server Consolidation Power Benefits

Server consolidation through virtualization can save over 80% on power consumption

– Purchase fewer servers and infrastructure– Run the equipment at a higher utilization

Requires understanding and planning– What are workloads?– What are server capabilities?– Planning and configuration tools– Monitoring and reporting tools

What Is Optimized Storage?

Consolidated platforms– Shared resources, higher utilization

Tiered storage– Different storage for different workloads

“Pay as you grow” configuration flexibility

– Capacity, performance, connectivity

Performance management– Minimize disk accesses to use larger

capacity disks

Managed capacity– ILM, minimize/prune full copies, use

incremental copies, and redundant data elimination

Applying De-duplication

First Instance Duplicate Instance Modified Instance


Use Case for De-duplicationState of Virginia

Before De-duplication

73 remote offices, backup to local, direct-attached tape drives

No local IT staff

Daily backup required five hours per site

Six hours to restore entire server

With De-duplication

Four hours to backup all 73 offices via existing WAN (56k-T1) to central de-dup server

45 minutes to restore entire server - files restored in seconds

Centralized management & control

“De-duplication enabled us to reduce administrative support requirements by 80%, reduce backup windows by 90%, and recover lost files & servers in minutes rather than hours.”

Call to Action Check List

Get an executive sponsor

Determine your data center power capacity– Are you near or at limits?

Assess your utilization rates and power efficiency– Are you managing your current assets wisely?

Identify and address low hanging fruit first– Do you have stranded servers, over cooling or inefficient data center cooling,

under-utilized storage?

Use TCO when planning new projects– Some technology refresh projects can fund themselves through operational cost

savings

Create an energy strategy– Employ a cross-functional team that treats the data center as a core business

operation of your organization
