This guide covers two common DRBD Proxy implementations. The first method uses DRBD proxy in a newly configured two-node DRBD cluster to replicate data to a peer over a high latency WAN connection; this method is common for customers looking for a disaster recovery solution. The second method demonstrates adding a third off site (stacked) node, to a pre-existing high availability cluster using DRBD Proxy; this method is very common for customers who are already using DRBD for high availability, and would like to add disaster recovery capabilities.
