Oracle DB's preferred method of data storage is for you to hand it disks for Automatic Storage Management, ASM. It then takes care of replication and storage by itself.

In practice, this might be a little more performant but incurs significant manageability costs. If you're a committed Oracle shop, it's worthwhile. If you just want one or two database servers and you already have preferred storage methods, use those. (Or, more realistically, use PostgreSQL.)
