Hello,

Does Elasticsearch have a storage limit that it can handle?  
Does this limit go to RAM and / or CPU? Is there a formula?

And in the case of 3 or 5 node clusters how do we understand the maximum storage that can be had?

Thanks

Daniele

It is often limited by heap size. Have a look at [this webinar](https://www.elastic.co/webinars/optimizing-storage-efficiency-in-elasticsearch) for details.
