RAC Technologies Matrix for Linux Clusters

RAC Technologies Matrix for Linux Platforms

Oracle will support the Oracle software on clusters comprised of RAC compatible technologies and supported software combinations
Please consult your hardware and software vendors as not all vendors may choose to support their hardware or software in every possible cluster combination
For RAC database and server virtualization support see here.
To use Oracle Clusterware, even in a non-RAC environment, the RAC hardware and software requirements must be met (unless otherwise stated.)

NOTE: The information in the following matrix applies to all Linux platforms unless otherwise stated in the platform specific section.

Technology Category	Technology	Notes
Network Interconnect Technologies	Ethernet 100 Mbps or 1 Gigabit NIC's and Switches	Cross over cables are not supported
