I'm currently in the process of planning an Exchange upgrade, and I'd like to use CCR (Cluster Continuous Replication) as a DR mechanism. It looks like I need to find a way to stretch a VLAN across the WAN. This sounds like a terribly painfull idea, but according to a post from one of the links below,
"MSCS requires a stretched subnet for geographically-dispersed clusters. In my experience, setting up a VLAN is a fairly straightforward and simple process. If you are experiencing difficulty, I recommend contacting your network hardware vendor, as they can probably walk you through the process pretty quickly."
What am I missing?
As per Microsoft's document,
"1. The private and public network connections between cluster nodes must appear as a single, non-routed LAN (for example, using technologies such as VLANs to ensure that all nodes in the cluster appear on the same IP subnets) between the three sites.
a. All three-site public interface must be on same subnet
b. All three-site private interface must be on same subnet"
I'm really not sure how to go about setting this up. Does anyone have any experience here?
