In Oracle 10gR1, Oracle introduced Automatic Storage Management (ASM) and changed the way we think of managing database storage. Exadata is the first Oracle product to rely completely on ASM to provide database storage. Without ASM, databases would not be capable of utilizing the Exadata storage servers at all. Because of this, ASM is a hard requirement for running Exadata. While ASM may not be a new technology, the storage servers are a concept that had not been used prior to Exadata.
