¹ OEM and ODM switches that ship with or will run SONiC in a production environment Reinvent your operating model with SONiCWhen it comes to the network operating system (NOS), there is a revolution underway. If you’re reading this blog there’s a good chance you’re a part of it—or ready to join. The traditional vertically integrated networking software stack has some inherent limitations, and it’s driving a fundamental shift in the approach to enterprise networking. And that revolution is driving an important evolution of open source enterprise networking, with Software for Open Networking in the Cloud—or SONiC.Since our announcement of the Enterprise SONiC Distribution by Dell Technologies earlier this year, we have continued to evolve this platform, improving the manageability and validation of SONiC on Dell platforms and achieving consistent API and CLI support for all features:Cables & optics qualificationPerformance & scale measurementsScale-out L2/L3 fabrics (VxLAN – EVPN Overlay)Scale-out L3 data center fabricsL2/L3 multicast top-of-rack/aggregationThe availability of a fully supported SONiC distribution with industry-leading manageability is exciting for our industry and for customers. SONiC, based on Linux with containerized microservices, was designed for cloud architecture from day one. The challenge has been to extend the benefits and flexibility of cloud to enterprise and service provider customers, who have unique requirements to integrate SONiC with their data center and network stacks. Enterprise SONiC Distribution by Dell Technologies provides the API, CLI and hardware configuration automation to create the bridge between these two worlds, and it unleashes rapid innovation and customer empowerment unlike anything we have seen in networking.Recently, I had the pleasure of participating in a SONiC industry roundtable, hosted by IDC’s Research Vice President, Datacenter Networks, Brad Casemore. We were joined by Microsoft’s Dave Maltz, VMware’s Pere Monclus and Comcast’s Yiu Lee to discuss the networking revolution that is underway, and how it’s driving the evolution and increasing adoption of SONiC. In fact, as Brad described, IDC is seeing growing demand for switches that ship with or will run SONiC, and forecasts a SONIC data center switch market that will reach $2 billion by 2024¹.Vive l’évolutionThe industry networking software stack traditionally has been vertically integrated with the hardware, along with proprietary management and telemetry features. While the integrated model provided management and support for enterprises and service provider customers, it had many limitations including a slow innovation cycle and limited flexibility to customize the software stack for different deployment options. These limitations were significantly amplified with the transition to cloud and modern applications. Traditional networking was not designed to support an empowered developer community that requires self-serve provisioning, rapid development and implementation of features and automated application deployment. The industry experimented with many network operating systems and open source community projects to resolve this disconnect, with mixed results—until now.SONiC has evolved into an industry software platform with a significant ecosystem and consistent growth in features and adoption. This is the result of deliberate design and investments to solve the root cause of the issues:SONiC is Linux-based NOS with a containerized architecture, which allows developers to leverage all the industry investment in bare metal automation, container management tools and lifecycle management. There is no need to develop separate tools for networking from the rest of the data center stack (compute and storage), as has been the case for traditional networks.Infrastructure managers, developers and site reliability engineering teams are able to use their familiar observability tools, dashboards and processes for networking immediately, and have direct integration with the rest of infrastructure, accelerating project timelines and improving availability dramatically.The cloud-native architecture of SONiC makes it possible to support different silicon and CPU options in many hardware form factors, which expands the use cases significantly to edge, SmartNICs, 5G, NVMe-oF appliances, etc.Additionally, the Enterprise SONiC Distribution by Dell Technologies includes support for API, CLI and hardware configuration for all the features, enabling seamless support for current data center and network deployments. Developers and infrastructure managers no longer have to choose between forward looking cloud architecture and optimization of current deployments with automation.This increasing maturity of SONiC means the time is right for adoption. In our roundtable discussion, Comcast’s Yiu Lee talked about how SONiC delivers the reliability and ease of day-in, day-out operation without additional investment in development resources, particularly as feature sets have become more mature and the SONiC community has gotten stronger.It is really exciting to be at this point in the development—in the evolution—of SONiC, and it will be great to experience the acceleration of innovation that is made possible by this new architecture.I encourage you to get some additional perspective on SONiC by watching the replay of the SONiC industry roundtable. In doing so, I think you’ll see that the time is right to evolve your network infrastructure.Related Links:Replay: SONiC Industry Roundtable Hosted by IDCDell Technologies and SONiC: Open Source Networking That Checks All the BoxesEnterprise SONiC Distribution by Dell Technologies
A world-renowned expert on human parenting and infancy with more than 130 published articles in medical, anthropology and psychology journals, professor of anthropology James McKenna boasts a special talent: tap dancing.McKenna, director of Notre Dame’s Mother-Baby Behavioral Sleep Laboratory, is a leading expert on “co-sleeping,” which involves conducting research on the benefits of mother and infant pairs sharing a bed together. However, when he is not knee-deep in his research, McKenna also teaches the Irish American tap class.“I tap danced pretty much all my life in one form or another,” McKenna said. “I started when I was two or three years old watching a Fred Astaire film in black and white in Boston.”McKenna said when he saw Fred Astaire dancing on the screen, his two-year old self ran to the two-foot wide hard wood space between the living room carpet and dining room carpet, looked at the television and “started tap dancing with perfect beats and rhythms and rolls.”“I just could do it,” he said. “I could always tap dance to any music that has a beat. I don’t know why, but it’s been a great joy and a wonderful thing to do. It’s like playing drums with your feet.”After this talent surfaced, McKenna said he pursued it further by taking more formal dance lessons. He taught tap for five years at Pomona College until he was recruited to be a faculty member at Notre Dame. When he arrived in the fall of 1997, McKenna said, he discovered the University did not have a dance department, so he worked on starting a tap class. After a year of preparation, McKenna taught his first tap class in the fall of 1998.Senior Allison Griffith, a current student in McKenna’s Irish American tap class, said she and her friends planned to take the class together. With majors in English and American studies, Griffith said she thought there was no better time than her senior year to try something new.“It is a blast,” she said. “At least for my friends and I, it’s what we look forward to for most of the week.”Initially unsure of what to expect when enrolling in the class, Griffith said she now knows how much time and practice goes into a tap dancing routine.“My expectation before was that it would be a class that people kind of trickled in and out of, and maybe they were just taking it for fun,” she said. “What I’m realizing is that tap is definitely a really difficult skill, and it takes a lot of time and practice to get down.”Previous students have written to McKenna saying they performed their tap dancing routine at their wedding reception with friends who were also in the class, he said. He said he believes the class remains meaningful for the students that take it.“I think Notre Dame students are usually very self-critical,” McKenna said. “There are very few classes where students are able to be non-judgemental of themselves, and to relax and be who they are without the kind of strain and struggles that all of us go through when you care about doing well.”The class has proven a less-traditional, yet still learning-focused environment, Griffith said. McKenna tells his students from the start that they will make mistakes, she said, but that it is okay because they are learning a completely new skill.“A lot of times at Notre Dame, we’re so fixated on making sure we do everything exactly right,” Griffith said. “A lot of us are afraid to make mistakes, and a lot of us are used to not failing — especially in a class setting. It’s very rare to have something to work towards that’s not a paper or an exam. We’re working towards a performance, and that’s really fun.”Griffith said everyone should consider taking the class, regardless of their dancing background.“I had not danced since like first grade,” she said. “Absolutely still take it. Probably a majority of the people in the class had never danced before, or did when they were really little.”A transformation occurs once students put on their tap shoes for the first time, McKenna said, and students should not be afraid to sign up for the class.“It is such a joyful exercise,” he said. “All your troubles blow out Washington Hall windows. It’s done in a very easy, relaxed manner. I have not had one single person — of all the people that have taken this class — that couldn’t do just fine.”The class will present its end-of-the-year recital Tuesday around 8 p.m. in South Dining Hall, McKenna said. It is free to students, and the class performs about six numbers.“It’s very raucous and joyful and really fun,” McKenna said. “These are students that never really saw a pair of tap shoes. I think they’ve all surprised themselves about how much they really learned.”McKenna said he thinks the class is so popular among seniors because they take it for no other reason than their personal satisfaction and joy in tap dancing as an activity.“It really becomes this really absolutely joyful, no-holds-barred experience for the kids, and they let themselves go in there,” he said. “It is one of their truly joyful, restful, self-assuring spaces at the University.”Tags: anthropology, Dance, Irish American tap class, McKenna, recital, tap dancing
