Sample Test Plan

The following evaluation test plan will walk you through basic setup of the InfiniBand-based switching
fabric, introduce you to some of the ULPs (Upper Layer Protocols) supported on the fabric, and perform
some basic tests that showcase the fabric's performance.

Overview

•

“Requirements” on page 67

•

“Network Topology” on page 68

•

“Host and Switch Setup” on page 68

•

“IPoIB Setup” on page 69

•

“IPoIB Performance vs Ethernet Using netperf” on page 70

•

“SDP Performance vs IPoIB Using netperf” on page 71

Requirements

Prerequisites

This test plan requires basic knowledge of Linux administration, networking protocols, and network
administration. This test of basic functionality and performance of the system should be completed in 3
days or less.

Hardware and Applications

•

A minimum of two x86-based servers are required for demonstrating some of the basic
functionality of the switch and the associated ULPs. To take advantage of the high throughput and
