I’ve recently started to play around with OpenStack and decided the best way to do so would be in my home lab. During my first attempt, I ran into quite a couple of hiccups that I thought were worth documenting. In this post, I want to talk about the prep work I needed to do before I began the OpenStack install.
For the initial build, I wanted something simple so I opted for a 3 node build. The logical topology looks like this…
The physical topology looks like this…
It’s one of my home lab boxes. A 1u Supermicro with 8 gigs of RAM and a 4 core Intel Xeon (X3210) processor. The hard drive is relatively tiny as well coming in at 200 gig. To run all of the OpenStack nodes on 1 server, I needed a virtualization layer so I chose ProxMox (KVM) for this.
However, running a virtualized OpenStack environment presented some interesting challenges that I didn’t fully appreciate until I was almost done with the first build…
Nested Virtualization
You’re running a virtualization platform on a virtualized platform. While this doesn’t seem like a huge deal in a home Continue reading
In this post we’ll look at how to create arbitrary topologies and push configuration to Nodes in UNetlab via REST SDK. We’ll conclude by extending our sample application to create and configure a 3-node topology and enable full connectivity between all nodes.

AT&T picks Ubuntu; Microsoft Azure slashes prices; OpenDaylight opens internships.
The Brocade Services Director (formerly known as SteelApp Services Controller) lets you automatically provision, deploy, license and manage the inventory of thousands of ADCs in an “as-a-service” model, using the Brocade Virtual Traffic Manager as the core application delivery platform. The solution also enables a new consumption model for customers deploying ADC services. This allows ADC services... Read more →

One of the things I insist on is learning the theory or concepts behind the technologies, rather than just learning how to configure the technology. This is often more difficult than it seems, though, because it’s hard to find (and often read) the documents that describe the technology — they’re often written in a language […]

The future of IT is rapidly changing. The transition to private and public clouds is forcing the need for integrated and elastic infrastructure. These changes are the impetus of a new role (and customer) called the Cloud Builder or Cloud Architect. Cloud Builders look at applications and data requirements from the perspective of business goals, not static technology silos. CEO Rich Napolitano details the parameters and implications of this new role in a blog post, and also outlines how Plexxi’s tools enable Cloud Builders to drive agility and workflow integration across what were once disparate compute, storage and network domains. Give it a read.

ITBusinessEdge: Converging Your Way to a New Data Center
By Arthur Cole
Vested interests in the IT industry have a lot riding on the hope that the enterprise will want to keep some of its infrastructure in-house rather than push everything onto the cloud as the decade unfolds. But this is only likely to happen if on-premises hardware is low-cost, highly scalable and maintains a tight footprint. This is why so many designers are touting converged and hyper-converged Continue reading
