somewhere there is a support matrix, which OFED version supports which RHEL 
version, but I also would need to search for it. Anyway, ofed-1.4 is already 
included in 2.6.18-164. So no need for any additional compilations. 2.6.18-194 
(RHEL5.5) also still mostly has OFED-1.4, but with an important mellanox 
driver backport (you will still additionally need a beta version version to 
get reliably QDR with recent chips). So if you have mellanox QDR HCAs and your 
connection is flaky in between SDR and QDR, just compile OFED-1.5, if works 
fine with Lustre (fortunately recently no interfaces changes anymore). But 
still make sure you compile Lustre against that stack...


I also just updated our download page a bit and also uploaded sources for 
kernel, lustre, tar and e2fsprogs.


Cheers,
Bernd
