Got a pair of old HPE gen8 1U servers that are chewing through fan packages like nobody’s business, replaced at least five burnt-out fans on them in a similar amount of years.
We’re running a mix of HPE, Dell, and Fujitsu servers and they all absolutely suck in their individual ways - HP(E) adds a bunch of arbitrary hardware limitations which we have to work around, Dell intentionally degrades our multi-system setups with firmware updates, and Fujitsu’s boot firmware goes absolutely pants-on-head retarded if you’re doing netboot first.
We’ve gotten some Supermicro systems now as well, and they’ve been a real treat in comparison, though their software UX feels like it’s about two decades behind.
