I confuse about VVOL mechanism. for example, if an expert apply wrong storage policy on a VM (Apply Archive storage policy to Database server), how system detect it?
do VM IOPS monitor?, is there any IOPS threshold for any Storage policy based on SLA model?, I don't understand monitoring system on VVOL
A good explanation of how SPs are deployed and what safeguards are available are details here: https://blogs.vmware.com/virtualblocks/2017/01/16/understanding-storage-policy-based-management/ Careful design of SP criteria and tight ACLs should prevent issues with archival SPs, etc.
VM object IOPs limits can be set in vSAN 6.2 and later: http://pubs.vmware.com/Release_Notes/en/vsan/62/vmware-virtual-san-62-release-notes.html http://cormachogan.com/2016/02/19/vsan-6-2-part-4-iops-limit/
