John Hermanski is a Technical Marketing Engineer at Dialogic. John has spent many years at Dialogic in Sales, Support, Marketing and Engineering roles. Recently, he finds himself in the enviable position of spending most of his time playing with new technologies and applying them to Dialogic products. This would include lots of system and network virtualization. He is thankful that telecom is now all IP, all the time, and he no longer needs to spend any time looking at SS7 specs.

Why Automation Is Key to Your OPNFV Deployment (OPNFV Demystified Part 7)

While OPNFV and Openstack provide a convenient virtualized environment for deploying and running network-oriented applications, there is another whole dimension to what may be done with it. With conventional computing, you need to wheel in another box, install things, and then modify your networked environment to take the new hardware into account. With a virtualization, you avoid dealing with hardware each time you need to increase an application’s capacity, and can “spin up” additional virtual machines and then configure the environment accordingly. And, in a well-designed OPNFV environment, all of this can be done automatically.

Real-World OPNFV Implementation – Networking (OPNFV Demystified Part 6)

So by now, you must be wondering what sort of differences we found in deploying OPNFV in a blade server environment? To be honest, not a lot. Some initial ’issues” stemmed from some unfamiliarity with blade servers and their storage and networking environments. We first did the OPNFV deployment on individual rack mount servers (RMS) [I should note that OPNFV at that point was the 1.0 Arno release, and it was a little green]. In parallel, we familiarized ourselves with the blade environment in general – setting up, partitioning, and mounting storage arrays, basic blade switch and network setup, and remote system management. For the grand finale, we successfully combined the blades and the more stable OPNFV 2.0 Brahmaputra release.

The most important difference between the two environments was network setup.

Real-World OPNFV Implementation – Traps and Tips (OPNFV Demystified  Part 5)

In the previous blog on OPNFV Demystified I described deploying OPNFV on a collection of rack mount servers (RMS) using Fuel as the installer of choice. I want to continue by going over the areas that may need some clarification, traps I fell into, and mention a few things that I really want to emphasize as I went through the deployment process.

Real-World OPNFV Implementation – The Hardware (OPNFV Demystified Part 4)

You may not have, as I did, the luxury of choosing the array of hardware – rack-mount servers (RMS) or Blade servers - to be used for your OPNFV implementation. I’m going to assume you’re not rolling in a rack full of blades, fiber switch fabric, and storage arrays, but have to make do with what you hope are adequate 1U or 2U machines. I’ll mention later some of the interesting twists encountered with a blade setup, but let’s start with RMS’s in the blog.

At this point you may be holding the OPNFV ISO in your sweaty hand, just itching to get it into a DVD drive in a convenient system from whence a fully-formed cloud will quickly spring.

Ummmmm – not so fast. Let’s talk about some things you first really need to have and really need to do.

The Components of OPNFV (OPNFV Demystified Part 2)

by John Hermanski

Before we can look at the components of OPNFV, let’s start back with a definition from my last blog. “OPNFV is basically an Openstack deployment framework, with emphasis on the networking side.“ This means that we have at least 3 pieces here – Openstack itself, a way to deploy it, and some networking “extras.” That might lead you to ask – “Well, why don’t I just use Openstack, if that’s at the core of things?”

Intro to Building a Carrier Grade Cloud Operating System Using OPNFV (OPNFV Demystified Part 1)

Configuring, deploying, and managing a fully operating cloud environment is not for the faint of heart. Despite the popularity of Openstack, the premier open source cloud environment, “it's still widely known for being hard to install and deploy.But, installations and deployments don't often fail as a result of OpenStack itself; more often, it's due to the amount of time and resources it takes to get it up and running.
