Customers Ask Two “Green” Questions
1. What is LSI doing to be a Green company?
2. How are we making our products Green?
LSI Proprietary 3
• Establish LSI as a recognized environmentally friendly (Eco-Sustainable) company– CEO Abhi Talwalkar has committed to reduce our company’s GHG emissions by 15%
by 2012 – Carbon Disclosure Project (CDP)
• Collecting data on greenhouse gases and carbon footprint
• Deliver environmentally friendly and highly efficient products and services that have both a positive green impact and offer economic benefits to our customers. – Work actively at the forefront of standards bodies to enable green technology– Push to be recognized as a Green Partner by OEM customers, and in turn help them
be successful
LSI Answers
LSI Proprietary 4
The “Green” Buzz!
• Environmental consciousness– Regulations – WEEE, RoHS now– Aim to reduce carbon footprint and meet Energy Star guidelines– Publicity about climate change– Ethics and social responsibility
LSI Proprietary 5
The “Green” Buzz!
• Environmental consciousness– Regulations – WEEE, RoHS now– Aim to reduce carbon footprint and meet Energy Star guidelines– Publicity about climate change– Ethics and social responsibility
• But there are economic reasons, too– One study: 63% of data centers are running out of power– Even if they have power, cooling is becoming an issue– “100 KWatt in computing power = $1M in infrastructure cost.”

Pressure Is on Data Centers - Cost
Source: Financial Times; Gartner report 2007; Stanford University; AMD; Uptime Institute; McKinsey analysis
• Data center cost 25% of IT budget- Server and Storage is typically 17%
• Hardware power usage driving costs up- $ in equipment requires a $ in energy- $ in energy per server requires $ for energy
for HVAC- Energy unit price increasing
US is at $1 per Watt per Year (@ 12cents/KwH)
BOTTOM LINE:
• Data centers growing 2x faster than revenue. Cannot be sustained.
• Have to make do (or even consolidate) with current levels of Power and Floor space.

Management Sophistication Has Not Kept Pace
• In 1975-1985, mainframes with 70-80% utilization handled 80% of computing demand
• Today, 80% of computing demand is handled by distributed systems with 5-30% utilization

Bad News!
• Data centers are power hungry and are very inefficient
… Good News• Problems are being addressed• Requires data centers to be
efficient and consolidate• Servers are moving in this
direction
… Spotlight is not on storage…yet
• So there is some breathing room
LSI Proprietary 11
Beware of Green-washing!
• Lots of vendor noise on green
– Awareness campaigns, best practices, articles, blogs, carbon credits, etc.– “…suppliers laid claim to energy savings in various thinly veiled
advertisements for their wares.” Byte and Switch, Sept. 19. 2007 – Buying carbon credits on behalf of customers,
Or giving away tree saplings at a trade show • Is power consumption really reduced?
• Green-washing: “virtual efficiency” – problem just moved elsewhere
– 33% power reduction in moving from 500GB drives to 750GB drives Or moving from RAID 1 to RAID 5 or larger RAID groups (e.g., 9+1 vs. 4+1)• What about performance?
– Positioning MAID against online storage• Only addresses data that is rarely accessed

1. Collaborate with industry associations, government agencies, partners, suppliers and customers.
2. Identify key issues and determine solutions.3. Deliver solutions to resolve the issues.4. Measure our results.
Feed the results of our efforts back to industry associations, our partners, suppliers and customers.

LSI Standards Initiatives
Standards
Green Grid• Industry consortium for green activity• General Member
SNIA Green Initiative• Founding member• Guides SNIA’s green activity• Working with EPA on Energy Star specifications
SNIA Green Technical working group
•Initial charter is to define green metrics• Weekly conf calls & quarterly face to face• “UnpluggedFest” to determine appropriate metrics, workloads, and testing methodology
Storage Performance Council
• Creating a “power” subgroup• Led by Sun, Seagate, LSI
Other
• Carbon Disclosure Project (CDP)• Electronic Industry Code of Conduct (EICC)• EH&S and operations programs and audits• Storage Bridge Bay Specification
LSI Proprietary 14
• Energy efficiency in our storage products– Efficiency of technology and features– Improved and redesigned green hardware
• Ease of management taking into account power consumption
Metrics to strive for• Improve performance per Watt• Deliver better and increased functionality/features per Watt• Reduce physical storage or power consumed by storage without
compromising performance and features• Reduce power used for infrequent access of information
ESG advantageLSI-ESG Systems are leaders in best of class Cost/Performance/Watt ratios,within IDC PB1-6
ESG Green Focus
LSI Proprietary 15
ESG Product Strategy
• LEAD with providing greatest economic benefit to the customer– i.e. NO green-washing!
• Areas of focus for product roadmap– Efficient use of power
• Drive power management• More efficient power supplies – better than 80% efficiency @ 20% - 100% load.
– Performance efficiency• IOPS and MB/s per Watt
– Consolidation by virtualization to reduce or fully utilize excess capacity• Thin provisioning• Also De-duplication & Compression
– Management and intelligent placement of data• Analysis and reporting• Online migration

Disk power usage delivered in phases
• Typical disk power usage– Idle consumption ~8-10W That’s $8 - $10 per year– Sleep consumption ~1+ W That’s $1.50 per year (approx)
• Phase 1 – Spin down unconfigured drives• Phase 2 – Spin down Hot spares, when not in use
– Planned for end of year
On roadmap• Phase 3 – Power throttling configured HDD based on usage• Phase 4 – Power throttling SAS and PCIe PHYs and
DRPM – HDD speed control
