What is an SAP "Active-Active Cluster"?

An active-active cluster consists of two independent server nodes at a minimum. The workload within a cluster resource is shared between the server nodes.

If a cluster node crashes the processes are resumed by the remaining cluster nodes. An active-active cluster configuration means that a cluster resource is active on all cluster nodes.

The aim of an active-active cluster is not only to provide high availability system but to distribute the workload between the cluster nodes. Applications with a very high workload like databases benefit from an active-active setup.
