2 Data Center Roadmaps Don’t know your past, don’t know your future… • This presentation will look at historical speeds for Fibre Channel and Ethernet and show trends that will help us predict the future • Speeds are getting harder to double: • Physics is getting in the way – attenuation is higher at high frequencies • Cost is paramount • Leveraging telecom speeds is more challenging • Amazing innovations still to come…

0G 2000 2010 2020 2030 Standard Completed Faster Speeds at a Slower Rate
• Fibre Channel keeps marching on at 2X jumps every 3-4 years • Ethernet speed jumps will be 2-4X, not 10X • New speeds like 2.5G and 5G are coming for campus environments 100G SFP+ • Ethernet expanding into new 1G markets such as automotive and PoE • 100G SFP+ is the Holy Grail that will require significant investment to accomplish
