[openib-general] IP addressing on InfiniBand networks

[James Lentini]

That would require systems to be configured using IB addresses. Can 
that be made feasible in non-trivial configurations? 

For example, how could name resolution be made scalable? If you want 
to resolve a hostname like foo.bar.com to an IB GID, then information 
about IB GIDs needs to added to the various name resolution systems 
(/etc/hosts, NIS, DNS,...). Adding GIDs to these databases doesn't 
seem like a prudent thing to do. GIDs come in different flavors 
(adapter specific and subnet manager assigned) none of which appear to 
be good candidates for large scale management.
