What server hardware requirements do I need for 100GB of data (over 6 million records). I use it only for text search (not more then 3-4 words per search).
Which server is better for Elasticsearch?
How much CPU, RAM and disk space (HDD or SSD) do I need for 100GB?
the link below gives some information about hardware requirements. http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/hardware.html
Some thumb rules: one of the most important requirements is the RAM.. my suggestion is to choose a server with at least 16 GB ram.
HDD will work good for you
