Hi Elastic search team,

We want implement hot, cold , warm tier in index ILM. So, we know how ro define cofigs but how we can map those tier with storage  
Lets say hot tier keep index data for initially 30 days with storage as SSD. And Cold tier will move the data after 30 days to NFS mount. So, how we do such configuration in Elasticsearch nodes.

Thanks,  
Ravi Gopalani

Elasticsearch can not move data between different types of storage witin a node so you need to have separate nodes with SSD and other nodes with slower storage so ILM can move data between nodes.

So where we define storage at node configuration. Can you share the sample.

The data path for each node is defined through the `path.data` setting in the config.
