GPFS/NSD on Linux/xSeries Using a 100 Megabit Ethernet Network

An IBM Redpaper publication

Abstract

A series of four benchmark tests were completed during 22-26 September 2003 at the IBM Benchmarking Center in Poughkeepsie, NY. The primary focus of these tests was to evaluate GPFS performance for HPC applications on Linux clusters. The clusters in this test were x345-based systems using FAStT900 disk controllers and EXP700 disk drawers. Each test was conducted on a different cluster network configuration [Gigabit Ethernet (GbE), bonded GbE, 100 Megabit Ethernet (MbE), and Myrinet]. Some of these test configurations are officially supported, while others are not.

This paper summarizes and interprets the results of the first benchmark test. It also proposes untested alternative designs that were suggested by these results.
