I want to do GNR. Is this a "special" feature that only IBM can

I want it for my x86. Now.<br>

Someone tell me which bit of the manual I've missed?<br>

We have a new GSS (not yet installed, waiting on power). The GPFS<br>
nodes are what appear to be fairly ordinary x3650 M4 systems.<br>
<br>
Despite having Redhat licenses, I expect us to use our standard CentOS<br>
6.4 on these systems (using the same update mirror and baseline<br>
configuration as our other systems).<br>
<br>
Or perhaps the question meant purchasing GPFS/GNR separate from a GSS<br>
purchase. I have no idea about that.<br>
