The market seems to have gone over pretty much completely to 1U compute nodes, with 2U or higher reserved for head nodes or other storage. The other trend is towards constant upgrading on relatively short time scales, with nodes being replaced every couple of years. Which makes me wonder what sort of longevity one would expect for 1U servers made in the last few years.
Some of us have to keep our hardware running a very long time, and I'm concerned that a lot of the 1U hardware isn't going to hold up in the long haul. I have some 2U nodes which are still cranking along in their 7th year. (Yes, it is well past time to replace them.) In that interval around 5 80mm fans (case or power supply, of 80, these were all rated at 50000 hours MTBF) have been replaced, most only in the last few years, and 1 disk out of 20 failed (in the 7th year). My limited experience with (older) 1U nodes was that the shrieky little fans were failure prone and didn't move enough air to keep the innards of the 1U case as cool as a 2U case. Heat is bad for longevity. Realistically, how long should one expect current 1U servers to last?
