Title

Storage Performance By: David Chisholm (dmchisho@learn.senecac.on.ca)

Introduction

In order to have our Koji Build Farm run as efficiently as possible we needed to find out which form of data storage would be the fastest overall. The candidates were:

  • PATA Hard Drive connected via USB
  • NFS share from HongKong
  • iSCSI network connection to HongKong

Approach

Benchmark using a linux untiliy called Bonnie++ written by Russell Coker.

The Benchmark was run 3 times on each medium, the results were then averaged together.

The command used is as follows: 

bonnie++ -d <location> -s 2048 -u root

Process

What happened while you worked on the problem? You had multiple iterations -- what happened at each milestone? Did you go down the wrong path and have to start over? What barriers did you encounter?

Discovery

What did you discover and learn during the process -- about the technology, the open source process, the community, yourself and your abilities, collaboration?

Results

What did you end up with? Did you solve the problem?
