<p class="MsoNormal"><span style="font-size:11.0pt">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.</span><o:p></o:p></p>
