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 (Oracle VM, LPAR, vPAR, LDOM, etc.) support see here.
  • For RAC database and SAP certification information see SAP support note 527843.

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).
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).
Fibre Channel over Ethernet (FCoE).
SCSI Support for two nodes only.
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.
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.
