I'm running a Kubernetes cluster on the Dell hardware, then another single node k8s cluster on the Lenovo, mostly to run Adguard home / DNS in case the big cluster goes down for whatever reason.
Hardware:
Two Dell r610s, each with 12 cores and 96 GB of RAM, running ESXi 6.7
Lenovo M900, 4 core, 16 GB RAM, Ubuntu and k3s
Synology 1515 with 12 TB usable
Synology 1517 with 32 TB usable
Juniper SRX 220H (Firewall)
Juniper EX 2200 48 port switch
UnFi in-wall WiFi APs
I run the following services, all in Kubernetes, with FluxCD doing GitOps from a repo in GitHub (for now, might move to Gitea later):
