just out of morbid curiosity, can very briefly explain the
connectivity differences between TCP/IB.  Does IB use the same 3
connections as TCP?  If not, is that why the connectivity limit
doesn't exist with IB or is there some other overriding design
principal in IB that allows lustre to push past TCP?  Not that any of
this has any relevance to anything i do, i'm just curious.

i'd love to have 2000 OSS's and 20k clients, but sadly i do not... :(
