Usually installing ESXi (since 5.0) on a host with just one CPU core will simply fail. If you only have a single CPU core then the installation terminates with the following error: CPU_CORES_ERROR: Your machine has  cpu core(s) which is less than recommended  cpu cores. Since I have a server in my lab with just one core ( why? good question 🙂 ) I needed to get myself a workaround in order to get ESXi installed in my lab environment. (more…)
A couple of years ago I started my lab by buying just one server and play around with it, deploying OSes, testing software and that kind of things. Over the years a lot more hardware has been added to the lab in order to be able to test all kind of scenarios and types of deployments like Disaster Recovery, Cross-site NSX, vSAN (Stretched Clusters), multi vCenter deployments, metro clusters.. you name it!

Currently i’m running my home lab environment on three physical Intel NUC devices. ESXi 6.5 is installed on each one of the NUCs and they are running a vSAN cluster (two M2 SSD inside each NUC, one for cache and the other for the capacity tier). Each NUC comes with 32 GB memory and a Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz installed as well. Due to the fact that the Intel NUCs are just not flexible enough for me to test certain scenarios I decided to expand my existing lab environment.
