that are possible to configure with Pacemaker.
Two-node Active/Passive clusters using Pacemaker and DRBD are a cost-effective solution for many High Availability situations
By supporting many nodes, Pacemaker can dramatically reduce hardware costs by allowing several active/passive clusters to be combined and share a common backup node
When shared storage is available, every node can potentially be used for failover. Pacemaker can even run multiple copies of services to spread out the workload.
Pacemaker 1.2 will include enhancements to simplify the creation of split-site clusters
