Data Center constraints

• Most common restriction on Data Centers?

– Power and Cooling, not floor/rack space

• System utilization is still low, even with virtualization

Why ARM Servers?

8

Why ARM Servers?

http://www.google.com/about/datacenters/

• Workload optimized solutions significantly increased TCO

– One size doesn’t fit all (anymore) – TCO is king at large scale

– New workloads and scale forced re-evaluation of what’s optimal

9

Why ARM Servers?

http://www.google.com/about/datacenters/

• Value chain is seeking increased innovation and choice

– Many ARM solutions coming to market - competition is healthy!

– Faster innovation needed by cloud & web leaders

10

Why ARM Servers?

http://www.google.com/about/datacenters/

• ARM business model enables innovation & differentiation

– It’s not just about a low power core – it’s what you put around it

– ARM cores already used in networking & storage components

– Experts in those fields can leverage their existing IP

Real world deployments
