Self managed cluster

A few questions on setting up a self managed cluster:

  1. I will be ingesting 100 gb data per day, want to do queries for a month. How to set up hot, warm, cold, frozen tier with self managed cluster?
  2. If I have to set up just hot, can I have just 2 nodes with 3 TB storage in each server?

Really impossible to answer as so little information is supplied.

Technically you certainly can setup a 2-node cluster, with enough space to handle your daily volume, but I presume there will be tools querying the data, and data needs to be ingested, and maybe somehow transformed or enriched. How many replicas of the data do you expect to need? How much CPU power for handling the queries. Do you even already know the main queries?

And it seems you are asking before you tried anything yet?

Your 100gig of daily data, do you understand its structure, before and once indexed into elasticsearch? Do you have a mapping? Is it something generic like "logs"? Or something more exotic?
