We have found that there are some vendors who dictate that they will
only support a Distro EX: RHXXX. Then if you layer the latest OFED
on top, then the support is nullified. Or to get any bug fixes or
support you have to uninstall the what you did and repeat the
bug/error. SO I think it is very important to keep the Distros very
close the latest OFED stack.
I believe the question that should be asked is "'How many IB
customers would like to use the OFED distribution if provided by the
distro?" The answer at least for the customer set we deal with is
pretty much unanimous. The fact is that customers are already
dealing with a distro for their base OS so obtaining the
interconnect code & support from the same sources is highly
desirable. When OpenIB was new (in 2004/5) and "common" IB code was
still in its infancy, the customer set was tolerant of 'build your
own' or vendor provided distribution mechanism. However if IB is to
become a ubiquitous interconnect, we in OFA have to strive to tailor
our deliverables to meet distro requirements. Until we do that, IB
will have difficultly gaining broader market acceptance.
Just my perspective.
