@Rick Merritt: it was good to see you at GreenNet last week in the City.
Question: what is the Ethernet PMD for the switch? RJ-45? If that is the case, then your statement needs revision:
"Switch X consumes about 2W per 56 Gbit/s Infiniband port, 1.5W on 40GE ports and 0.62W on 10GE ports. That's about on par with competing Ethernet devices some of which require external physical layer components that the Switch X integrates."
Because the 10Gig RJ45 ports today consume more than 5W.
If Switch X supports other (than RJ45) PMD's for Ethernet (like SFP+), then the power numbers look reasonable; I can also see how Mellanox leveraged its effort in IB switches to develop a product for 100G/40G Ethernet.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
