Exadata Storage Servers automatically delete old diagnostic and metric files.

Exadata requires a running database instance on all storage servers and database servers.

Redundancy for the user data that is stored in a database that is running on Exadata is achieved with RAID5.

Communication between a database and an Exadata storage flows over low latency 10 Gigabit Ethernet.

Exadata uses network affinity to determine which storage server data is written.
