Is it true that at least 128GB of memory is needed?

RustFS needs at least 2 GB of memory to run test environments, production environments need a minimum of 128 GB of memory.

We need to know the production concurrency and production data.

Preparing for trial use, the amount of data is uncertain—it could be very small or very large—but the documentation says at least 128GB is required, which makes it feel difficult to even get started.

Agree, better to give a simple guide for different scenarios, and how to get start with small scale business? because not all the scenarios require such high performance, especially when involved with HDDs.

You should actually base your data on your own actual business operations.

By testing it yourself, you can obtain your company's concurrency, memory, and disk metrics.

This isn't an answer to the original stated question; from here:

RustFS needs at least 2 GB of memory to run test environments, production environments need a minimum of 128 GB of memory.

Why? These seem made up, or there's a massive barrier to using RustFS in production. 128GB is steep, even if it's the total memory across multiple nodes.

Just looking at a single node stat in docker shows it doesn't need remotely 2GiB:

If you have enabled caching and have very high concurrency, you will need a lot of memory to speed things up.

If your data volume is small and caching is not enabled, RustFS is very memory-efficient.

It uses at least one-third less memory than other storage solutions.
