Hi Jason,
I'd like to provide my feedback about testing this code and running
NFS over RDMA over the software iWarp. With much appreciated help from
Bernard, I setup 2 CentOS 7.6 VMs and his v7 kernel branch. I
successfully, ran NFS connectathon test suite, xfstests, and ran "make
-j" compile of the linux kernel. Current code is useful for NFSoRDMA
functional testing. From a very limited comparison timing study in all
virtual environment, it is lacking a bit in performance compared to
non-RDMA mount (but it's better than software RoCE).
Excellent feed back, thank you.
Lets hear from NVMeof too please
I actually took a stab and gave this a test drive with nvme/rdma
and iser (thanks Steve for making our lives better with rdma tool add
link support), think it was v6 though...
There were some strange debug messages overlooked IIRC, and there
were some error messages, but things worked so don't know what
to make of it.
Pretty much the same feedback here, very limited testing on my VMs shows:
- functionally works
- faster than rxe
- slower than non-rdma (which sorta makes sense I assume)
