So don't buy it for an NSD server then :-)

I think you are missing the point somewhat. Well by several country
miles and quite possibly an ocean or two to be honest.

Spectrum scale is supposed to be a "scale out" solution. More storage
required add more arrays. More bandwidth add more servers etc.

If you are just going to scale it all up on a *single* server then you
might as well forget GPFS and do an old school standard scale up
solution.
