Can the Oracle Database use Exadata Storage simultaneously with traditional non-Exadata storage products?
Yes, databases can be concurrently deployed on Exadata storage and non-Exadata storage. Tablespaces can exist on Exadata storage, non-Exadata storage, or a combination of the two, and this is transparent to database applications. However, Exadata smart scans will only work if the tablespace(s), being queried, reside entirely on Exadata storage.
