Protocols used by Oracle RAC in an InfiniBand environment

There are 3 major components in an Oracle RAC cluster that make use of the cluster interconnect:

• Oracle Cluster Ready Services (CRS)

• Database or ASM instances

• Oracle Cluster File System (OCFS)

On Linux, each of these components is designed to communicate across a standard Ethernet network

using the UDP protocol.

When an InfiniBand fabric is used for the cluster interconnect, support for UDP is transparently

provided via InfiniBand's IP over InfiniBand (IPoIB) protocol. By default, all of the Oracle components

can transparently use IPoIB for inter-cluster communication. In addition to IPoIB, Oracle has developed

libraries that allow a database instance to use the User Direct Access Programming Library (uDAPL)

protocol for communication between cluster database instances.

Figure 2 is a pictorial representation of the protocols used in an Oracle RAC environment.
