Great, as long as it will continue to work with S3(Minio), it's good for me. I am already using MinIO with Trains (older version).

Was planning to do a upgrade soon.

I am using MinIO current with trains=0.16.4, if this will still be an valid option for ClearML (>0.17.0)?

Yes, you can still use it (and many other options, include local and cloud storage),

Hi, what’s storage ClearML is using? I am considering self-host clearML on a Cloud machine, while separated the data storage with our own machine (reduce network cost)

You can choose the one that works for you (Shared folder, S3, GS, Azure, Http).

EnviousStarfish54 the server uses local storage by default for the fileserver. However, as you've commented, it's entirely possible to configure your ClearML SDK to use different kinds of storage (Minio, s3 etc) and simply not use the fileserver
