In an Elastic cluster with more than two nodes, what other configuration is necessary to ensure the replication of the vital information? (i.e., SRM related object)
This information is available on the following page on docs: https://docs.dataminer.services/user-guide/Advanced_Functionality/Databases/Configuring_dedicated_clustered_storage/Cassandra-compatible%20database%20service/Deploying_Cassandra/Replication_and_consistency_configuration.html
Note that the URL of this page may change in the near future; in that case, the fastest way to find it is to go to the user guide and enter "replication" in the filter box on the left.
