So, we have a Hyper-V cluster running Server 2012 R2. We installed SCVMM and added the cluster. How, the Cluster is using a CSV to store virtual machines, which is running off a Storage Appliance the hosts are talking with via iSCSI. Everything is working great, but I've run into a problem, I want my VMM libraries to live on the Storage Appliance the cluster is using. Ideally, I'm wondering if there is a way to host a library share from a cluster? I'd like to create a LUN to store all my VM templates and have that LUN hosted by the cluster. I can create a LUN and assign it to a File Server role and share out the lun via UNC path, but what I'd really like is for that cluster name to be the VMM share, rather than installing the agent on a VM or something and then having the VM act as a proxy. Realistically, if I'm deploying a VM from my library share that's on the same storage appliance as the host it's going to is using the fewer network hops between them the better since internally my cluster is all 10gigabit. How do I add a library share that's not an actual server, but just a UNC path from a LUN? I've added it for now as a UNC path through my VMM server, but I'm worried it's going through that machine to go back to the cluster.
I know that Ideally with an SMI or SMP the SCVMM could probably use sancopy, how would that setup work though? Would I need to create a dummy VM and use iSCSI to connect it to a LUN, and then no traffic would actually go over iSCSI because it would just use SAN copy as long as my storage appliace is capable of SAN copy?
