Expansion of Oracle Exadata X10M Eighth Rack systems requires hardware modification. Compared with non-Eighth Rack systems, Eighth Rack database servers have one CPU, and less memory, and Eighth Rack storage servers have fewer CPU cores, less memory, less disk storage, and less flash storage.

You can expand Oracle Exadata X10M Eighth Rack systems as follows:

• Expand the database servers.

  You can expand each Eighth Rack database server by replacing the original 32-core CPU with two 96-core CPUs and expanding the memory. You can expand the memory by adding to the existing memory or replacing it with higher-capacity memory modules (DIMMs).

• Add more database servers.

  You can expand processing capacity by adding standard (non-Eighth Rack) database servers. Though not mandatory, upgrading the original Eighth Rack database servers before adding more database servers is recommended to maximize consistency across the rack.

• Add more storage servers.

  There is no upgrade kit to expand Eighth Rack High Capacity storage servers. However, you can expand storage capacity by adding more Eighth Rack High Capacity storage servers.

  You can also expand storage capacity by adding regular (non-Eighth Rack) High Capacity (HC), Extreme Flash (EF), or Extended (XT) storage servers.
