yakLab build out

The yakLab is a place where yaks are electronically instantiated for the purpose of learning and documenting. The lab consists of a virtualization host (virthost) which has 64GB of memory and hosts all the virtual machines, primarily for infrastructure.

We then have 3 mini-ITX based baremetal nodes with 16GB of memory, 110GB hard drive (single disk, SSD), with a quad-core CPU. The processing power of these machines is quite low compared to modern day machines, but they consume a relatively small amount of electricity, and don’t make a lot of noise (the CPU is fanless).

Here is a physical overview of the lab. Note that secondary and tertiary network interfaces are not shown here, but might get documented in future episodes.

Infrastructure build out episodes

In the yakLab build out, we’ll talk about several of the infrastructure build out scenes, including:

(NOTE I’ll update the list below with links to articles as they become available.)
