Open Networking for the Whole of Your Data Center Network
In the past, I’ve designed, deployed and operated networks of various sizes, needs and scopes. One of the perennial design points common to all of them is how to approach the out-of-band (OOB) network. When it comes to making sure your production network operates in the face of issues, the OOB network is often a critical component. But it also raises the question of how to build it, what components to use and how much they affect the “day job” of running the production network. These decisions haven’t always been easy.
Generally, there is a spectrum of approaches. On one end is the choice to go with the same gear that you are deploying in the production network. On the other end is the decision to just build the OOB network out of what you can get from the local or online electronics superstore. One can cause you budget problems; the other raises the question if your OOB network will be there when you most need it. All too often the most frugal designs win, and this can cause you to have to troubleshoot the OOB network before you can troubleshoot the production network. So the issue is more than just the initial acquisition cost, Continue reading

Cisco ACI in the CNPES Cert (Engineering Specialist)
Cisco’s current network programmability certs uses two exams per cert, with the second exam focusing on ACI. That represents the first ACI-focused specialist exams from Cisco, and a great reason to learn about ACI and validate that knowledge. Today’s post looks at the ACI-focused exam for the Cisco CNPES Cert exam: the 600-512 NPENGACI exam. We’ll look at both the exam and a related video course.

Overview
First, to set the stage, Cisco rolled out their network programmability (read: SDN) certifications over a period of months, mostly in 2014. Figure 1 shows these four certs, with the engineering specialist cert focusing on engineering and implementation.

Today’s post focuses on the second exam: the 600-512 NPENGACI exam. The name itself is a bit of a mouthful:

Basically, the NPENG 600-504 exam covers SDN implementation excluding ACI, NPENGACI 600-512 exam includes ACI.
