Hi Jason,
IB support in 9.2 is supposed to be stable enough.
Please note that Mellanox started supporting FreeBSD only recently. The dri=
ver in 9.2 was ported by someone from Isilon (Jeff Roberson) from OFA-1.5.3=
.
Since we started our involvement we entered some fixes to that driver (that=
were submitted into 9.2).
We also mapped various issues which needs to be fixed in the future.
We are now working on a major "face lift" to the driver - making it much mo=
re stable and with improved performance and features.
Regards,
Oded Shanoon
OFED-FreeBSD Team Leader

Thanks Anthony & Oded!
Would you say that IB support in 9.2 is stable enough for a production HPC =
file server?
Will do plenty of my own testing first, of course.
Regards,
Jason
