Hello,

I am struggling to see the difference between a 'Cluster' defined application and a 'Mirror' application.

Both are mounted via the iSCSI initiator in the OS and presented as a new disk in the Storage Manager of the OS (as a single disk if MPIO is installed and selected during the iSCSI connection setup).

This disk is then available for discovery in Hyper-V which it can be used as Quorum or CSV purposes if I am correct?

Could someone please clarify the diffecences and usage scenarion for a clearer understanding... As it is the difference between the Standard and Ultimate edition.

Also... Is there any reason why the Software cannot be installed on the Hyper-V Cluster 'Host' Nodes without needing two SAN nodes seperately?

Thanks,

Martin

Can you please explain what you have on mind?

Performance is not good at all if both target and hypervisor are run on the same host. And worst migration (vMotion or Live Migration or XenMotion) is not guaranteed. May work and may not work when needed. So maybe that's why dedicated hardware for SAN is required.
