Hyper-V and Disaster Recovery

I had a few questions around disaster recovery and Hyper-V environments.  I have a customer who wants to know why Replication Manager does not support CSVs (this came up during a VNXe discussion).  Is it a technical limitation of RM?  Does this same limitation apply to VNX arrays or is it VNXe only?

This same customer has a two-node Hyper-V cluster with CSVs that they wish to replicate to another cluster at their DR site.  I've read that RP\CE is a requirement to replicate Hyper-V clusters, yet I have also read that RP\CE does not support CSVs.  Is this correct?  Is there any whitepapers that outline some of the common Hyper-V environments and the best way to implement DR?

Thanks!
