Placement of the File Share Witness (FSW) on a Geographically Dispersed CCR Cluster
Hi Matt:
When planning for the public and private "heartbeat" networks in a geo-dispersed CCR implementation, do we need to have separate network links for the public/private networks (i.e. separate routers, switches, WAN connections), or can we use VLANs over a single wide area link?
The CCR Planning documentation at http://technet.microsoft.com/en-us/library/a26a07fc-f692-4d84-a645-4c7bda090a70.aspx says that "A separate cluster private network must be provided" and that "to avoid single points of failure, use independent VLAN hardware for the different paths between the nodes."
This suggests we should have two separate links, but I wanted to get clarification on this if possible.
Thanks for your help!
Jim
