For AI, you want DAOS storage. It runs in userspace, you can use FUSE and it's the fastest storage on the planet when it comes to bandwidth (see io500). There are good companies supporting it like croit, and with their software it's easy to manage as well.

While DAOS looks cool, from their roadmap it looks like they still don't have a fault domain larger than a server... Their erasure coding profiles also look pretty thin. I'm ex-Meta, our infra had vastly different availability and reliability requirements but that looks like it'd be painful to support at scale.
