[Pvfs2-developers] RE: PVFS2 seems tcp inclined ?

[Kyle Schochenmaier]

Amit -
The config file you sent looks like it should work for IB without tcp?
Which config options are you setting for the other cases?

Also, to answer your other question, BMI_ib used to use tcp (not
bmi_tcp) to setup connections and do administrative stuff, but you
should not ever see 'file data'  go over your ethernet connection.
