I have 3000 EPS from 300 log sources and retention rate is 1 month, so is 16Gb RAM 1Tb SSD for 2 eligible master-data nodes enough ? ---

2 master nodes are bad, see [https://www.elastic.co/guide/en/elasticsearch/guide/2.x/important-configuration-changes.html#\_minimum\_master\_nodes](https://www.elastic.co/guide/en/elasticsearch/guide/2.x/important-configuration-changes.html#_minimum_master_nodes). As for the rest, you would need to check how many GB that is. ---
