How To Use Link Aggregation (LAG) For Ethernet Over IB (EoIB) VNICs In Exalogic Physical Environment (Doc ID 1487342.1)

Last updated on DECEMBER 01, 2023

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 2.0.0.0.1 and later
Oracle Solaris on x86-64 (64-bit)
Linux x86-64

Goal

This document provides information and detailed steps on how to create and use Link Aggregation (LAG) over multiple 10Gbps uplinks from InfiniBand Gateway Switch and enable Ethernet over InfiniBand (EoIB) Virtual NICs in Exalogic Physical environment. This facilitates high availability as well as higher bandwidth for EoIB network path from Exalogic and other Oracle's Engineered Systems to external Ethernet LAN.

Note:

This document is applicable only to the Exalogic Physical Enviroments and it is not supported to use this procedure in Exalogic Virtual Enviroments.
