Ethernet Trends in Datacenters

• Robust datacenter networking

investment and growth with

numerous drivers including:

– Virtualization

– Ubiquitous connectivity and

continuous content generation

– Cloud models

– Storage access

– Server to Server traffic

– “Big Data”

10GbE Adoption Trends

• Strong growth but still

relatively low penetration

– Switches introduced 2001

– Adapters introduced 2004

10GbE Adoption Curves

• Hampered early by:

– high price

– low densities

– high power

Switch

• Factors falling into place for

next phase

– volume adoption

Summary

• Many factors and trends driving Datacenter networking

– Especially Ethernet

• 10GbE ramping strongly, but still minority of datacenter

and server ports

• Numerous 10GbE market drivers falling into place

– Impending volume adoption

• 40GbE and 100GbE

– Expect 40GbE to see broader initial datacenter adoption
