What does privacy have to do with running a network? Is protecting the privacy of users, customers, and the organization one of the responsibilities of the networking team? If so, what kind of information has to be kept private and how? Should privacy efforts focus on compliance, or on risk reduction? How are those different? On today’s Heavy Networking podcast we welcome Russ White to tackle these perplexing privacy questions.
Single pair Ethernet. That’s right. Ethernet over a single twisted pair, rather than the four you’re used to. Or two if you’ve got a little gray in your beard. Now, single pair Ethernet isn’t fast in the way we network engineers would normally think of fast. SPE runs at 10 megabits per second. But in the use cases SPE was designed for, 10Mbps is very fast indeed. To tell us all about single pair Ethernet is Peter Jones. Although Peter wears many hats in the networking industry, today he comes to the microphone as the chairperson of the Ethernet Alliance.
Today on Heavy Networking, we discuss NVMe over fabric, where your Ethernet and IP network is the fabric. Many NVMe over fabric discussions focus on what’s happening inside the storage packets themselves. This conversation focuses on the network. What does the topology need to be? What are the latency and loss characteristics of an NVMe transport fabric? What QoS tools should you be considering, how do they work, and when should you use them? Our guest for this vendor-neutral conversation is J Metz.
What’s been your experience with architecture vs. engineering roles? Are those distinct functions or combined in your organization? How do the roles interact? Does the architecture team hand down holy designs from their ivory tower the engineering team is expected to implement them? Is the architecture and engineering function more combined, where experienced engineers are expected to create an architecture and help put it in place? Ethan Banks and guest Pat Allen share their experiences with architecture and engineering roles from organizations they've worked in.
