I’m running LSI 9300-8e for the last 6 months in producution without
problems. I have Supermicro JBOD attached to it with SAS drives in

Perhaps SuperMicro is not eager to re-qualify their existing passive
hardware for 12Gb/s since they are mostly intent on selling
expander-based hardware which does need to be updated for 12Gb/s.
SAS is supposed to be good for something like 30 feet so only a poorly
laid-out passive backplane would have problems due to the higher
speed.
Google and WikiPedia were not able to shed any light on this issue so
I just took a chance.
