Also anecdotally: back in my sysadmin days, the Supermicros we had had so many more problems than the Dells. Granted this was 2012-2015 era hardware being run in 2018, so I can't say for certain if that's even remotely still true, but yeah.

The 'Micro's ethernets were all shot by the time we closed up shop so each had an expansion card for 10G ethernet at that point, and one we had to run VM management on 10G because the 1G we used elsewhere had shit the bed in that unit somewhere along the way and we couldn't be bothered to buy yet another card and tear down the server again for it. Plus management traffic was negligible.

I don't miss that job. Fuck being on-call.
