Can I surmise from all this benchmarking of the ib_srpt module that this
is now stable? Last I checked the git version still had a data
corruption bug.
I saw some patches submitted to fix this, but the OFED git repository
(http://www.openfabrics.org/git/~vu/srpt.git) shows no recent commits.
I'll check it in with some other patches before the weekend
You should use ofed-1.3 (srpt is in there).
http://www.openfabrics.org/git/~vu/srpt.git is for older ofed version (ie.
1.2.5 and 1.2)
With all these impressive numbers, I am eager to see SRPT/SCST
performance in the WinOF srp initiator environment using database loads.
Props to Vu and Vlad for this outstanding storage transport!
Kudo to Vlad - great job on scst, iscsi_scst...!
