Ok. I re-read the FAQ and I think the option in the Table is a bit misleading. I think it means it’s supported without direct disk access and that means GPFS client not an NSD. Sound right?

Does GPFS nodes with no direct disk access still mean RDMs?

Otherwise is not supported. SCSI commands is the reason. Furthermore on some versions I managed to crash the ESXi as well. -- Cheers On 25 Oct 2016, at 19.46, "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> wrote: Anyone running SpectrumScale on Virtual Machines (intel)? I?m curious how you manage disks? Do you use RDM?s? Does this even make sense to do? If you have a 2-3 node cluster how do you share the disks across? Do you have VM?s with their own VMDK?s (if not RDM) in each node or is there some way to share access to the same VMDK?s? What are the advantages doing this other than existing HW use? Seems to me for a lab environment or very small nonperformance focused implementation this may be a viable option.
