Can you provide us with more information on storage cluster, what is the logic behind ‘Storage cluster’?

The “Storage Cluster” is group of one or more elastic search node instances that connected together. So, this name represents underlaying physical nodes and as of now SapphireIMS has only one node to store the Log Analyzer data. In future as part of road map enhancement if we plan to introduce more than one physical node then same “Storage Cluster” name can be used by adding additional physical nodes as part of clustering.
