Once Upon A Time... • GHz was king • One architecture for everything • Out of performance? Add a new server!

24

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

25

And It Was The Right Time • Web workloads still exploding • Power&cooling are major concerns • Consolidation is key driver

26

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 27

And Had A Lot Of Success!

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

“[The Sun Fire T2000 servers] utilize less space and “Numbers consume don't much lie: less We experienced energy whileadeliverin 300% p

$700M+ in revenue since Dec. 2005 introduction “These servers could save companies millions.”

Winner--Best Midrang Sun Fire T200 28

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
