Just wanted to run a scenario by you for logic's sake:
I have two SANs, one is in one city, the other in another city, I just added 11TB of storage to apiece to them. I want to use the storage for NFS volumes to store VMware guests, and the goal is to have failover capabilities if one of the cities goes dark.
Does this make sense below?
Set up 5TB NFS volume on City 1's SAN
Set up 5TB NFS volume on City 2's SAN
Attach City 1's SAN to the City 1 datacenter vSphere
Attach City 2's SAN to the City 2 datacenter vSphere
Configure a SnapMirror relationship on City 1's SAN to perform nightly mirror of its 5 TB NFS volume to City 2's SAN.
Configure a SnapMirror relationship on City 2's SAN to perform nightly mirror of its 5 TB NFS volume to City 1's SAN.
The connection between the two cities isn't robust enough for an always-on DR plan for every VM. We are running nightly tape backups for the data on these guests as well.
