Hi Team,  
Currently, we have a 3TB data node, my question is do we have any restriction regarding disk size on ES node. And what would be the consequences of creating nodes with larger disks?

The two main factors that tend to limit how much data you can store on a node is often heap usage or query latency requirements. See [this webinar](https://www.elastic.co/webinars/optimizing-storage-efficiency-in-elasticsearch) for more details.
