Following on from my introduction Exalogic Blog Entry (Exalogic Networking Part 1) this entry describes the Oracle A-Team Exalogic Scripts to help facilitate a simpler ECU installation and provide an example on configuring a standard Oracle ACS type environment. The scripts and a pdf document can be downloaded using the link below :
This blog will summarise the functionality that is provided by the A-Team Exalogic Scripts. These expand upon the existing “Exalogic Configuration Utility” functionality simplifying repetitive jobs, for example creating VNICs on the switches, and building base environments.
Version 1.0.1 contains the following scripts that will be detailed later:
During the process of execution the scripts above will generate additional scripts that will be specific for Exalogic Rack they are being executed on.
Technical discussion on how to adjust Linux bonding configuration parameters depending on how a host participates in a given network. Limitations of link level failure detections and an easy solution within bonding driver to overcome it.
Technical discussion on an approach to achieve virtualization through network layers. Comparison between InfiniBand Partitions and Ethernet VLANs. Consolidation and Isolation of logical network channels leading to virtualization. How to satisfy computing platforms need to be multi homed ? If these are topics of interest to you, then read on.
In the context of Oracle's Engineered Systems, I am going to explain how an InfiniBand network is actually created using various building blocks of hardware and software. Includes a very basic view of a host participating in IB network and their connectivity to achieve redundancy and high availability.
