homeLAB Storage performance test – iSCSI (Single HDD, Striped HDD) and VSAN

Hi everyone.

Time to do a posting of my homeLAB storage and its performance.

First of the following:

PLEASE NOTE: THIS IS IN NO WAY AN INDICATION OR REAL WORLD PERFORMANCE OF ANY TECHNOLOGY MENTIONED.

What I mean by the above note is that these are test I performed on my homeLAB system to gauge the performance of the storage I have. This is in no way a true reflection/statement of performance of what similar products will have in a real world setup. As always, please ensure you engage with the vendors for best practise setup and configuration to best suit your requirements.

For my homeLAB setup and configuration, browse to my homeLAB setup on this site.

Performance tests:

  1. Why did I test the performance?
    1. I just wanted to see what the performance of my setup is. I have various configurations of disk and technologies and wanted to see the performance differences if any.
  2. What did I use to test?
    1. I used VMware’s IO-analyser, which can be found here: https://labs.vmware.com/flings/io-analyzer
    2. I am currently doing a lot of testing with vCD-SP, vRA and NSX and needed to know some performance characteristics.

I made some remarks under each test which shortly describe the setup, and my observations

SimpleHDD

Setup: iSCSI over 1Gbps network to a Windows Server running Starwind 6. There is a small cache of 2048MB configured in Starwind. Starwind image is on a Single Disk, 1.5 TB Seagate Harddisk 7200rpm.

Observation: First test is a max IOPS test of the device which resulted in about 16 000 IOPS.

Observation: The following test is a max Throughput test of the device which resulted in about 69.24 MBps.

StripedHDD

Setup: iSCSI over 1Gbps network to a Windows Server running Starwind 6. There is a small cache of 2048MB configured in Starwind. Starwind image is on a dual Disk, 1.5 TB Seagate Harddisk 7200rpm. These disks are striped.

Observation: First test is a max IOPS test of the device which resulted in about 15 000 IOPS.

Observation: The following test is a max Throughput test of the device which resulted in about 44.92 MBps.

VSAN

Setup: 3x Hosts VSAN Cluster running version of vSPhere 5.5. Each server has a 64GB SSD (Transcend) and a 250GB HDD (Seagate 7200rpm). It should be noted that the default VSAN policy was left in place.

Observation: First test is a max IOPS test of the device which resulted in about 24 900 IOPS.

Observation: The following test is a max Throughput test of the device which resulted in about 24 MBps.
