Run IOMeter on an Azure Linux VM with Azure Premium Storage


I had to do some IO testing for a customer with Azure Premium Storage. I was able to get some numbers using this command:

dd if=/dev/zero of=test.dat bs=1M count=10000;rm –f test.dat

However, wouldn’t it be cool if we could use the same IOmeter as Windows users in Linux? Well, it turns out this is actually possible!

I first created a 4 disk RAID 0 array on my DS3 size VM using these instructions: http://azure.microsoft.com/en-us/documentation/articles/virtual-machines-linux-configure-raid/

Once I had my RAID array, I then followed the instructions to add GNOME to my Linux VM: http://blogs.msdn.com/b/cloud_solution_architect/archive/2015/05/02/remote-desktop-to-your-linux-azure-virtual-machine.aspx

I used CentOS 7.1 from the Azure VM Gallery. Unfortunately, it turns out that you can’t just sudo yum install wine to get Windows application support in Linux because IOMeter is a 32-bit Win32 application and CentOS 7.1 only supports 64-bit Windows apps out of the box.

This Wiki article talks about how to install IOMeter on Linux: http://www.linuxintro.org/wiki/Iometer. However, there are a few issues with it. Here’s what I did:

wget http://downloads.sourceforge.net/project/iometer/iometer-stable/2006-07-27/iometer-2006_07_27.linux.i386-bin.tgz
tar xvzf iometer-2006_07_27.linux.i386-bin.tgz
cd iometer-2006_07_27.linux.i386-bin
cd src
chmod +x dynamo
sudo yum install ld-linux.so.2
sudo yum install libstdc++.so.6
sudo ./dynamo

This guide talks about how to install Wine on CentOS 6 (also works on 7.1): http://stackoverflow.com/questions/20971960/the-right-way-to-install-wine-on-centos-6-64bit. Here’s what I did:

1) Open another terminal window
2) Type this in the command window to download the Wine source:
wget http://downloads.sourceforge.net/project/wine/Source/wine-1.7.42.tar.bz2
3) Type these commands in the terminal window:

$mkdir wine64
$ cd wine64

$cd wine32
$wget http://downloads.sourceforge.net/project/iometer/iometer-stable/2006-07-27/iometer-2006.07.27.win32.i386-setup.exe

$sudo Iometer.exe

Once IOMeter launched, I selected my RAID disk for each of the workers:

With a 4K Read Access Specification for each worker thread: (Note: Host cache for each data disk was set to none; these are not official benchmarks and are specific to my environment)

This is actually a littler better than the DS3 VM Specification:

The same test on a scaled up DS 13 with the same 4 disk RAID 0 array:
