Suggestion to contact Virtuozzo:

They offer cloud solutions, such as storage, to resellers and distributors for resale, and focus on joining forces to compete against the cloud hyperscalers.

I see 2 different types of partnership options as I understand it: Either selling Storj solutions to MSPs directly or providing storage as part of the Virtuozzo storage offering.
