Luke My understanding is that GPFS Native RAID is only supported on two types of Storage. Power 775 Disk Enclosure - 384 disks -water cooled. GPFS Storage Server.
You are right that the clues to this are not obvious. Here are two of them that I found in the docs. Here is an extract from the latest GPFS FAQ. Q2.18: On what platforms is the GPFS Native RAID (GNR) function supported? A2.18: On Power, GPFS for AIX V3.4.0-9 or later, and GPFS for Linux on Power V3.5.0-2 or later, support the GPFS Native RAID function on P775 servers with P775 Disk Enclosures. See https://www.ibm.com/developerworks/wikis/display/hpccentral/IBM+HPC+Clustering+with+Power+775+-+Service+Packs On System x, GNR is supported on the IBM System x GPFS Storage Server. See http://www-01.ibm.com/common/ssi/cgi-bin/ssialias?infotype=AN&subtype=CA&htmlfid=897/ENUS112-218&appname=USN Here is the first line from the Chapter on Native RAID from the GPFS Advanced Admin Guide: Note that GPFS Native RAID is not supported on GPFS 3.5 without APAR IV16031.

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