Kubernetes Cluster
Lester Vecsey
The basis of this project is a Ceph FS (filesystem) and a reasonable high speed network.
The actual project is a master server with a dual port 100 GbE network card, and two worker nodes that are also capable of 100 GbE network connectivity.
A 10 GbE network card servers as an uplink to the rest of the network.

An uninterruptable power supply by CyberPower, model CP1500PFCLCD was also added to the list. It will power all three servers.
Also required was a 5-tier shelf from Temu, to hold everything. A Wi-Fi printer was optional.
Similar to the above list, however the only storage drive is M.2 which can be 2 TB.
There are no dedicated boot drives because the M.2 will have a partition for that.
It has a single port Intel 100 GbE network card.
There is no TP-Link TX401 in this one, since the only uplink needed is the 100 GbE link.
For the chassis I went with more of a cube shape, with the Node 804 model.
Fiber optic interconnects connect between the master server, and each worker node. Thus no intermediary switch is actually needed, for this very tiny or minimal cluster configuration.
