Assuming that they end up hiring a full time ops person at 500k annually total costs (250k base for a data center wizard), then that's 42k extra a month, or ~$70k. Still 200k per month lower than their next best offering.

It's really not necessary.

I have four racks rather than ten, and less storage but more compute. All purchased new from HP with warranties.

Ordering each year takes a couple of days work. Racking that takes one or two.

Initial setup (seeing differences with a new generation of server etc and customizing Ubuntu autoinstallation) is done in a day.

So that's a week per year for setup.

If we are really unlucky, add another week for a strange failure. (This happened once in the 10 years I've been doing this, a CPU needed replacement by the HP engineer.)

I replaced a couple of drives in July, and a network fibre transceiver in May.
