Ethernet is Dead: The Series
Episode I: The Lord of the Ring
Token Ring
Episode II: Return to the Disk
Fibre Channel
Episode III: The Empire Strikes Back
ATM to the Desktop
Episode IV: The Rise of the “S” (serial, speed, scalable)
Infiniband as the ubiquitous interconnect
Episode V: The Net Who Would be King
Myrinet, Quadrics, Infiniband
TOE, RDMA/IP
The Ethernet ecosystem has always evolved to address the needs of the user community.
It always rises to the challenge of other technologies.

Ethernet is evolving again
Higher Bandwidth – 10GigE
Lower Latency• Lower latency NICs &• Host-side improvements.
Improved Switching Infrastructure• Need low-cost, low-latency
switches.• Likely to arrive in the blade
environment before we see them elsewhere.
Ethernet: Will our Hero Survive?
Ethernet: The Precision I/O Contribution
• Extend the life and investment of existing GigE networks Software only solution significantly increases GigE performance today Available for Beta testing today!!!
• Transparently & dramatically increases server application capacity Higher I/O throughput Improved CPU utilization / Higher transaction capacity Lower latency
• Non-disruptive migration path to future 10GigE networks 10GigE HW/SW solution available soon Only required on one end of the connection - no client changes Supports incremental deployment - one server at a time
• No new fabric, protocols, packet formats, or infrastructure required• No application or operating system changes required
