Hi, I am planning to use Elasticsearch Cluster with 4 different servers with each Node on one server. Out of which 3 Nodes are Master Eligible and Data Nodes and the other is Coordinating only Node(Kibana is also running on the same machine).
Data ingestion would be 2GB daily. I am planning to have 2 Primary Shards and 1 Replica Shard for each index(Having too many Primary Shards would effect Performance).
CPU - 4x2.2ghz
Disk - 600gb
Please let me know if I am missing anything. Your help is highly appreciated.
