Hi,<br>
<br>We also tested OFED 1.3 on PPC64 with SLES10 SP1 UP1 with connectX and Arbel HCAs<br>

I don't know about OFED, but I've tried various things on 64KB PAGE_SIZE<br>
systems and it seems to work. It wouldn't surprise me if there are<br>
issues since the drivers and firmware gets a lot less testing in such<br>
situations but it "should work" -- I'd be happy to help debug if anyone<br>
has concrete problems.<br>

OFED was tested on PPC64 with RHEL5.1 which works with 64K pages as a default.<br>
This was tested with our ConnectX cards (mlx4 driver)<br>
I think IBM are using the same OS for their ehca cards too<br><font color="#888888">
