Can someone kick me in the right direction for backing up hyper-V guest servers in a 3 node cluster utilizing CSV's with a VNX 5300?  I would like to utilize our DPM 2010 server to back up the machines.  I am very frustrated with the documentation that EMC provides, I don't know if it exists or I just can't find it.  I understand I need some sort of Hardware VSS provider on the Host machines and then I think I need a snapshot lun that DPM will backup, I just can't find the correct information to accomplish this.  Any help would be more then apprecitated.
