This part in particular caught my eye:
> Step 2: Diagnosing broken machines
> As is typical in setting up large GPU clusters, we found that about 10% of the machines failed to boot, mostly due to physical issues with the servers. Some issues we encountered included: unconnected or miswired Ethernet cables, hardware issues in iDRAC, broken power supply units, bad NVME (nonvolatile memory express) drives, missing internal wires, and network cards or GPUs failing to show up.
This is a crazy high failure rate. Is this standard for traditional data centers too?
