In my previous role, I had the opportunity to wear many hats, including Network Administrator. Our go-to ITBuilds vendor before I moved on was Extreme Networks. When I initially started my position, the campus was a Cabletron customer, then Enterasys, and lastly, Extreme Networks (Believe it or not, there’s more than one way when it comes to Network Vendor selection). Now the transitions did come upon company acquisitions. And after each acquisition, we did our due diligence and reviewed…

How to become a network engineer, some advice for those interested in IT

For those of you who are interested in becoming and network engineer or administrator, welcome! I wanted to start with “Why Computer Networking,” and maybe it will help you find your “Why.” My first blog post dates back to 2013 when I was just a Network Administrator. Before that, I remember reading technical blogs and…

I’ve made quite a few changes to my site. The first thing you’ll notice is the name change. I decided it was time to move away from the Apextier domain name. I originally received the domain from a close friend. My original intent with the site was using Apextier to run a side job for web dev work years ago. I eventually stopped building websites. Apextier sounded cool at the time and became a useful place for my technical blog. I decided that something like LifeNetEng was more personal and…

Being a Systems Engineer or really a “Sales” Engineer, I speak with lots of IT folks about products that Extreme Networks sells. Rarely do I have conversations around hardware features such as feeds and speeds or physical components. Every competitive ITBuilds vendor mostly has access to the same commodity ASICs. In the networking and infrastructure world software has become King or Queen. Software is the driving factor for change and creating some healthy competition in the Networking industry.

You’re probably thinking why are we still talking about NAC? In my opinion, NAC is one of the bests ways to apply dynamic assignment of access control and gain visibility to where devices are connected to the network in real-time in an agent-less fashion. By the way, us ITBuilds folks hate agents. We don’t want to be in charge of one more application, especially if its deployed on thousands of machines.

I recently attended a CWNA course taught by none other than Devin Akin, wireless guru and co-founder of CWNP. During the course I was reminded about how attenuation can become your best friend when building high density Wi-Fi networks.

If you make your way into the world of ITBuilds, you’re bound to come across a decision path on how you should handle network expansion. Should your default method always be to extend or stretch your layer 2 bridge domain? The root of the answer can be found when discussing the why. Let’s take a look at some of the use cases I’ve come across within enterprise network environments: Device Requirement Device “A” needs to communicate with device “B” and those two devices are “required” to live on…

I recently heard the term “best of breed” used when discussing network vendor selection. I was surprised by this answer because you don’t hear it too often. The more I thought about it, why not “best of breed” selection? My time as a network and infrastructure supervisor has taught me that a data center environment can be full of different compute and storage vendor products. Our SAN environment consists of Pure, Tegile, EMC, and even QNAP. Each product has its place. Pure serves the VDI…

Being able to track your work efficiently is a very useful skill. For years I completed my work but rarely tracked my work in a project management professional (PMP) sort of way. Sure, I’ve done the weekly reports, sticky notes, Outlook tasks, and Outlook calendar block scheduling, which are all useful. However, simple project management skills help create a consistent and straightforward approach to managing time, resources, and tasks. I’ve seen organizations take an all guns blazing PM…

We recently upgraded some of our WAN link bandwidth capacity from 1Gbps to 10Gbps to decrease transfer rates of backups across our two data centers. Traffic between each site encrypts with Checkpoint physical open appliances. The upgrade to the WAN links involved installing 10Gbps Intel NICs in our Checkpoint open servers. Once all the pieces were in place, I started to test everything using iperf3.
