This tech-guide describes a setup consisting of two highly available Pacemaker clusters in two sites, with a routed IPv4 or IPv6 connection in between that can range from a few Mbit/sec up to 10GBit/ sec, depending on the IO load imposed on the cluster nodes.
Disaster Recovery with DRBD Proxy: Configuration Guide
Implement your disaster recovery solution using off site block level replication. DRBD Proxy mirrors your local DRBD resources over a WAN or Internet connection despite possible network performance or high latency. This tech guide illustrates the configuration of a 3-node DRBD setup with stacked resources and DRBD proxy for WAN replication.
In this guide we will show how to utilize Amazons EC2 and LINBITs DRBD/DRBD Proxy combo to replicate data to the cloud for off-site replication. Common uses of this type of implementation are Disaster Recovery and Disaster Avoidance.
