Defining DSE topologies

Define the topology for DSE at the cluster, datacenter, and node levels.

The Lifecycle Manager (LCM) topology consists of cluster, datacenter, and node models. LCM uses the topology for installing and configuring DataStax Enterprise (DSE) at these levels. When installing and configuring DSE clusters, the topology provides flexibility and powerful inheritance mechanisms.

LCM requires manually defining the cluster topology when creating a new DSE cluster. For existing clusters, import the cluster topology automatically and LCM will add the cluster models on your behalf in the Clusters workspace, provided all target nodes use a single SSH credential. The logical LCM model should reflect the actual physical topology of a cluster.
