The ram:disk ratio is described here: [ECE RAM to Storage Ratio](https://discuss.elastic.co/t/ece-ram-to-storage-ratio/101878/8?u=alex_piggott)

To set that via the api

- get the `/clusters/elasticsearch/ID/metadata/raw` And save the json body
- edit the json to add the FS multiplier change as per the link
- post that back to `/clusters/elasticsearch/ID/metadata/raw`
