There are 61.44 TB NVMe drives (best price I've seen right now is ~6200. They were ~4800 earlier this year). You can have a 1U server with 32 E1.L slots so you should be able to fit ~1.9PB raw storage into 1U for a little over $200k. Don't know how business financing works, but at 8% interest with a 5 year amortization, that's a bit over $4k/month.

Do you have any good recommendation for such 1U server with 32 slots? Thanks

Shows 2U in order to fit 32 drives, but hopefully you can find a 2U slot for this absolute monster of a storage box if you have that need.

This one is 1U and supports dual socket CPU and 6 TB RAM:

I've never done procurement so can't really speak to recommendations. I just see that the products apparently exist.

There's also 32 drive 1U JBOF enclosures for more expansion:

Our ops team actually wanted to do this, but we on the project have nightmares from putting 1PB of database on a single host ><
