Storage Networking Roadmaps Storage Networking Roadmaps

• More data • More applications • More bandwidth • More HDD capacity • Slower disk drive speeds?

5 The 2015 Ethernet Roadmap

• The Ethernet Alliance has developed the 2015 Ethernet Roadmap • Find out more at www.ethernetalliance.org • The 2016 Ethernet Roadmap will include a chart on backplanes that would include this project

6 The Fibre Channel Roadmap Doubling and now Quadrupling every few years

• Fibre Channel is focused on optics and the 1X/4X paradigm • No longer HDD Interface • “The Fibre Channel Roadmap” will be released in October and includes: ‒ Physical maps like the 2015 Ethernet Roadmap ‒ Electronic version soon at www.fibrechannel.org/roadmap.html ‒ White paper

7 SAS Roadmap SCSI Trade Association (STA) has this roadmap

• SAS has doubled data rates like Fibre Channel for over a decade • 12G SAS shipping now and 24G SAS expected in 2018

13 2.5/5GbE HDD Interfaces Seem Very Late

• Comparable technologies were defined a decade ago ‒ SAS mainly using 6G specifications today • More competition is growing with PCIe • Should we fracture the market between GbE and 10GbE into 2 more speeds? Thank you
