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.<br><br>Thanks<br><br>Mark<br><br>This message (including any attachments) is intended only for the use of the individual or entity to which it is addressed and may contain information that is non-public, proprietary, privileged, confidential, and exempt from disclosure under applicable law.
