  • 1.  Mark as flash as default

    Hello. I'm having trouble marking storage devices as flash. These are SSDs on RAID-arrays shared over ISCSI (Starwind).

    Is it possible to create a claim rule to mark ALL iscsi-luns as flash on a host? (6.5).

    I see that marking as flash on one host do not change the device on the other hosts accessing the device, so I guess I have to add this claim rule on all hosts.

    What is the best way to proceed?

    I think that if you take your time and mark them once, those should remain as SSD.

    Probably this article may point you to further steps:http://www.vladan.fr/how-to-tag-disk-as-ssd-vmware-esxi-5-x/

    I have a StarWind-based all-flash cluster running as dedicated storage for vSphere cluster. Never used to mark the drives as flash though since it works perfectly without it too.

    The main reason I want to mark as flash is that I want the OS in VMs to see the storage as flash also. And the most important reason "just because" :smileyhappy: :smileyhappy:

    We have many LUNs and many hosts, so it will be many "mark as flash"'-es.

    And also the annoying part that it the datastore is in use on any host we cannot mark as flash.. :\
