Almost since the inception of the software-defined networking market, many observers have speculated whether VMware NSX or Cisco Application Centric Infrastructure would emerge as the industry leader. Some enterprises, such as Sugar Creek Packing Co., based in Washington Court House, Ohio, have opted to deploy NSX and ACI in concert, thus maintaining flexibility and reaping benefits of both products.
We recently caught up with Sugar Creek senior network engineer Wes Dawes to talk all things networking -- from the development of his own career to the evolution of the industry. He also shared which SDN option he'd recommend to other enterprise network managers -- NSX or ACI -- after deploying both.
This interview has been lightly edited for length and clarity.
How did you get into networking?
Wes Dawes: Originally, I was more of a systems administrator, working with servers and storage. I worked in the financial industry and I was looking to move, as the bank I worked for was looking to be sold. This job just happened to become available here at Sugar Creek, about eight years ago. Originally my position was 50% networking and 50% servers and storage, and it kind of developed into 100% networking.
What was the transition from servers and storage to networking like?
Dawes: It was quite a transition. I had very little experience with networking equipment. The most I'd really ever touched it was if I went out and did field work for the bank, maybe I'd help the network guy on site. I'd help rack up the equipment or I might patch in some cables, but other than that I had very limited experience.
How did you learn?
Dawes: I primarily learned on the job. Just a lot of reading at night, and picking up some spare equipment and working on it and trying to figure things out without breaking anything in our production environment. After I got my feet wet a little bit, I did some training, got a few certifications and started really enjoying networking, and continued my education.
What about networking appeals to you?
Dawes: It's just kind of an exciting part of the industry to be in. When I first started, it was new to me, so that was part of the appeal. But then, over the last few years, with everything developing and becoming more software-defined and being able to do things programmatically across the network, it's making it even more exciting. There have been all kinds of changes over the last few years and lots more to come.
How is Sugar Creek approaching the changes afoot in the networking industry?
Dawes: One of our latest adventures was probably within the last two years: We did a connected factory in Cambridge City, Ind., jointly with Cisco. So basically, everything in the plant -- wireless, routing and switching, telepresence, phone system, everything down to the factory floor -- is wired to the hilt. It's amazing how well everything works together and the data we are able to collect.
Within this last year -- as soon as we finished that project -- we jumped right into a software-defined data center project that we did with VMware and their NSX product. We also have some Cisco ACI in there.
Why deploy both NSX and ACI?
Dawes: When we started exploring NSX and ACI, it was still very unclear who was winning that race and which one was going to be the technology to end up with -- who was going to be the leader and give us everything that we needed. So we more or less hedged our bets on that decision and said, 'let's just put both in, and if the tides change, we can more easily maneuver around. Or maybe they are both going to be great technologies, with one complementing the other.'
After using both NSX and ACI, which would you choose today?
Dawes: There have been a lot of developments since the time that we made the decision, and I'd say VMware is definitely the route that businesses need to look to nowadays. Now, don't get me wrong, because each technology has its pros and its cons, and it all depends on the existing environment it's going into. We were in an environment that was 99% virtualized to begin with, so NSX is the right choice for us -- along with all the other VMware technologies we decided to go with in here, like [vSAN].
VMware NSX's programmability makes it much easier to make changes on the fly, without having to worry about going into the data center and running new wires or moving things around. Another big thing for us is the security features with microsegmentation. Before, we would always secure the edges of our data centers, and now, NSX allows us to bring that security down to the virtual machine level. We can get a little bit more granular with security and really take care of things.
I'd say by the end of this year, we'll probably have our security set up to a point where we feel comfortable with it. And then it will be normal operations after that.
How do you use ACI?
Dawes: It's deployed, and we don't really do a whole lot with it. It's really there for monitoring at this point. It allows us to have a single pane of glass from the Cisco side, so we can just go in and, at a glance say, 'Oh yeah, we've got some network problems going on around the ACI infrastructure.' It allows us to pinpoint issues quickly, rather than having to do more manual troubleshooting. We don't use any of the real nitty-gritty ACI features.
Does your previous experience working with servers and storage help you in your current networking position?
Dawes: It does, and that was true from the beginning, when I first started on the network side. Understanding the servers and the storage and how everything is configured on that end, and being able to tie that into the network, that's allowed us to keep our team small and make quick decisions. It's definitely helping as I go forward, now that I understand the servers the storage and I understand the network piece of it. One complements the other.
How much does the networking team interact with the server team?
Dawes: There are a few of us on the network side, and there are a couple of guys on the server side. We all sit in the same room, in the same cubicle area, and we are constantly working together. We have that division of, 'Hey, we're really good at the networking side -- but we're good at the server stuff too, and we can do that if we have to.' And the server guys are kind of the same way. They focus more on the servers, but they understand enough about networking, because they work with us so much. It really helps make us feel more like one team than two.
What advice would you give to young IT professionals just beginning their careers?
Dawes: I'd tell them to explore all of it and figure out what they enjoy, because that's the most important thing: coming to work to a job that you enjoy. And if I was trying to sway them toward the networking side of things, I'd probably end up telling them, 'Hey, the networking side is really exciting right now. There are lots of changes coming, lots of opportunities for growth, new areas that other people don't have experience in -- so the sooner you get that experience, you'll be better off.'
Would you recommend they seek out opportunities to learn about programmable networking tools like NSX and ACI?
Dawes: Absolutely. That technology is here to stay. It's still early; it's going to evolve and change a little bit, and that will be for the better I'm sure. But I don't see that going away.
