2.1.1.1 X9M-2 Eighth Rack Upgrade Options

Upgrade of Oracle Exadata Database Machine X9M-2 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 upgrade Oracle Exadata Database Machine X9M-2 Eighth Rack systems as follows:

• Add a CPU upgrade kit to the database servers, which adds 1 CPU to each database server.

  As part of adding the CPU upgrade kit, you must also:

  1. Physically move the network interface card from PCIe slot 2 to PCIe slot 1.

  2. Run /opt/oracle.cellos/ipconf.pl to reconfigure the OS network configuration files.

• Add a memory upgrade kit to the database servers, which adds 4 x 32 GB DIMMs to each database server.

  On database servers with 384 GB of memory, you must install the memory upgrade kit if you want to install the CPU upgrade kit.

• Add more database servers.

  You can expand processing capacity by adding standard (fully-configured) 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 standard High Capacity (HC), Extreme Flash (EF), or Extended (XT) storage servers.
