It seems like many flavours of datacenter ethernet are settling down! Couple of years ago, there was 10Gbps x 4 and 10Gbps x 10 for 40Gig and 100Gig ethernet, some what influenced by the legacy InfiniBand camp. I am glad to see 25Gbps getting the approval of the majority.
We did have healthy discussions around 25/28gig SerDes couple of years ago after OIF / CEI standard for 25G class designs was approved:
There are certainly specific issues, complexities, and challenges of moving to 25G or higher, and I'm glad to see this decision by IEEE. For futher reading/info: Steve Tarnovich at EDN posted an article on 100GbE recently, and this is a major topic that we deal with at DesignCon.
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.
