I have a requirement to handle 1TB data per day? what is the best suitable hardware configuration for this? I want to handle it by starting multiple nodes of elastic search on the same sever under one cluster. I have a server with following config-

- 12 core
- 20 TB HDD
- 256 GB RAM  
Is it possible or should I use multiple hosts with less server configuration?

You can do but it is not suggested, if you place all the data in the same server, because there is only one machine, which means you don't have failure over once the server is down. but you know it depends to your scenario.
