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 (KVM) support see here.
For RAC database and SAP certification information see SAP support note 527843 on https://support.sap.com/.

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 1 Gigabit NICs and switches. 10 GigE recommended (see notes).	10 Gigabit Ethernet solution is supported generically. Crossover cables are not supported. Use the correct type of cable (Cat 5, 5e, or 6).
Network Interconnect technologies	InfiniBand (IB) RDS over IB is supported. IP over IB is supported.	Oracle only supports Oracle InfiniBand HCAs.
Storage technologies All storage products must be supported by the server (host) and storage vendors	Fibre Channel (FC)	Switch required for greater than two nodes (if the storage system does not have enough FC port for the cluster nodes).
Storage technologies All storage products must be supported by the server (host) and storage vendors	Fibre Channel over Ethernet (FCoE)	None
Storage technologies All storage products must be supported by the server (host) and storage vendors	SCSI	Support for two nodes only.
Storage technologies All storage products must be supported by the server (host) and storage vendors	iSCSI	Support up to 30 nodes. Private GigE storage network is required. The iSCSI accessed storage must be supported by the system and storage vendors.
Storage technologies All storage products must be supported by the server (host) and storage vendors	NFS file server	NFS file servers do not require RAC certification. The NFS file server must be supported by the system and storage vendors. NFS protocol version 3 (NFSv3) and version 4 (NFSv4) are supported.
