@Pete-S said in Building your own lab:
The reason they are cheap is that they show up in large volumes at the same time and usually they are without CPU and RAM. Most hobbyists and a lot of people in IT are not familiar with multi-node servers so they don't know exactly what it is and how to use it. Some confuse them with blade servers as well.
True, I was not aware of multi-node servers.
Whether those 4 servers are individual, except cooling system and server chassis?
Why there are only two power supplies for 4 nodes?
How it would be if require any maintenance on 1 node? you can manage individual or impact other 3 nodes in this process?
