24

Once Upon A Time...

• GHz was king• One architecture for everything• Out of performance? Add a new server!

25

But Sun Thought Differently

• Pioneered multi-core in 2000• Introduced UltraSPARC T1 in 2005• 32 threads in 8 cores at <80W

26

And It Was The Right Time

• Web workloads still exploding• Power&cooling are major concerns• Consolidation is key driver

27

We Were Very Careful

• New technology• Single-threaded vs.

multi-threaded• Careful with floating-point• Lots of trainings/workshops• Tools for:

> Assessing workloads> Optimize deployments> Optimized web stack

opensparc.net/cool-tools.html

28

And Had A Lot Of Success!

$700M+ in revenue since Dec. 2005 introduction

“We are ecstatic with the cost, throughput performance, and power economics of the Sun Fire™ T2000 servers... We experienced a 50% decrease in server power consumption.”

“[The Sun Fire T2000 servers] utilize less space and consume much less energy while delivering significantly improved performance.”“Numbers don't lie: We experienced a 300% performance increase after we started using the T1000s – in a third of the space, and at a third of the power consumption...”

“We improve performance so much and reduce costs in so many ways with the T2000 that it represents a 10X improvement in price-performance for our entire architecture.”

“These servers could save companies millions.”

Winner--Best Midrange Server:Sun Fire T2000

29

Then, we Introduced UltraSPARC T2

• Double the throughput• Double the memory• Better single-threaded

performance• Built-in 2x 10 GbE• Free, efficient virtualization• Free, fast crypto
