Now that we have seen how my home network and my home lab looks like we are ready to start building the mega-project I have in my mind.

So what do I actually want to build?

The goal is the be able to spin up multiple lab environments and test multiple features with different software combinations. I will need this because each customer environment is different and the way how infrastructure behaves all depends on the version and interoperability of different software versions.

I have 768 GB of RAM capacity in my Compute cluster. I have 256 GB of RAM capacity in my Management cluster.

Below you will find a resource calculation sheet that I created to calculate (and determine) the capacity requirements for one single lab environment.

Single Site:

Dual Site:

When making the following calculation 768/127 = I can run 6 single site labs When making the following calculation 768/254 = I can run 3 dual-site labs. Or I can run a combination of a few single sites and dual-site labs :-)

When we visualize this, this looks like this for the single site version:

When we visualize this, this looks like this for the dual site version:

Each “network topology” per site is explained in this article: Virtual “physical” network (Cumulus Network) To give you a quick peek this is the drawing of each network topology per site:
