Re: 10GB Ethernet Cards

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

Please keep in mind that the minority of OS running on Power Systems is 
IBM i.  AIX is much larger in terms of total instance count, and 
everything IBM does is not just for IBM i (although I think this group 
might wonder why it's not ;-)  )  There are many shops that need the 
extra bandwidth that 10G Ethernet provides and they use load balancing 
and fail over on the lines.

The salient point here is if you need it, it's there, also IBM provides 
IBM i nearly everything it provides the other OSs running on Power 
Systems.  A good thing.
