go from supporting GSS and ESS to allowing and supporting native raid for

has some good tech in this area and IBM has shown with the Spectrum Scale

I have a demo/test version of GPFS running on a 5 year old Thinkpad laptop....
And we have some GSSs in the lab... Not to mention Power hardware and mainframe
