I worked in Datacenter Ops for a decade+, running 3-6 private datacenters as an HPC/Nix admin wearing many hats. The amount of work involved with physical plant, circuit management, staff coverage, weather events, regulation, travel, hardware upgrades, replacement...the list was seemingly endless.

That's also not to mention hopefully you never have to staff augment for junior-level tasks. Try hiring someone to correctly rack and stack an entire rack. You just end up re-doing it yourself or paying CDW to ship you an entire pre-assembled rack the next time.
