I am planning on deploying a NAS/iSCSI target cluster of two Dell NX3100 servers running Windows Server 2008 R2.
Here are some of the environment details currently:
- I have two office locations on opposite sides of the US that will host one of these NAS/iSCSI target servers each.
- The locations will also have XenServer hosts at each location. Each site has a DC/DNS XenServer VM, amongst others.
My questions are as follows:
1.) Is a point-to-point connection or site-to-site VPN more suited for this setup? Maybe a third connectivity solution?
2.) I plan on using half of the array on the NX3100 servers as iSCSI targets for location-respective XenServer VHDs. I mean to run the VMs off of their local NX3100, but backup/snapshot to the off-site NX3100 for disaster recovery.
3.) Are these ideas silly/unfeasible? What are some foreseeable problems or misunderstandings I may have with this environment?
