I created a system that booted 12k+ diskless blades via PXE and running Ubuntu (it was built to scale to 30k+, but we never got there).
This generally works well, but I'd say there are about 0-20 blades that crash a day due to some sort of memory corruption issues.
Due to the fact that I was operating remotely from the hardware, I never really got a chance to resolve it... also... just a simple reboot would fix it (and the blades booted in ~60 seconds, so it wasn't a huge issue).
So, on large enough scale... this can be an issue to consider.
- yjftsjthsd-h 4y agoIs that caused or exacerbated by being diskless, though? Or is it just inevitable that 12k+ machines are going to have a certain rate of memory errors regardless?
- latchkey 4y agoThat's the thing, I don't know. It could be a whole bunch of issues, but I thought it was interesting to note what I see at scale while doing this.
