InfiniBand Fabrics – Advanced Training

Part Number: MTR-IB-OST-A

Duration: 2 Days

This course is focusing on multicast, along with fabric design guidelines and what obstacles you should avoid when designing a fabric.
We will also focus on how to select and configure the most suitable routing algorithm for a chosen topology.
In addition this course provides the necessary skills and knowledge to effectively diagnose and troubleshoot InfiniBand fabrics.  
You will also receive and overview of the required tools to effectively compare InfiniBand fabrics

This course is a continuation of the Fundamentals of InfiniBand Fabrics Course (MTR-IB­OST-B, MTR-IB-OPEC-3). 
It is designed to provide more advanced materials to support InfiniBand Level 1 and Level 2 technologists by focusing on fabric design, tuning and troubleshooting, multicast, and SNMP principles. 

What's in it for me?

Do you find yourself needing to understand InfiniBand with multicast or needing to know how to properly design fabrics? Maybe configure SNMP monitoring with InfiniBand? How about using virtualization with InfiniBand?
We have created this InfiniBand advanced course for just that reason.

Much of the Financial Services Industry (FSI) has adopted InfiniBand to accelerate their multicast applications. This advanced course is going to focus on multicast, along with fabric design and which tools to use when comparing InfiniBand fabrics. What obstacles you should look out for and avoid when designing your fabrics. Do you need to set up SNMP with InfiniBand? Or basic RDMA with InfiniBand? We have a section for that as well, plus much more.

This course is a continuation of the InfiniBand Foundations Basic Course (MTR-IBOST- B). It is designed to provide more advanced foundation materials to support InfiniBand Level 1 and Level 2 technologists by focusing on fabric design, fabric tuning, multicast, and SNMP principles.
