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

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

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

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
