Now that the team is back from VMWorld, we wanted to share the configuration for our VSAN demo that drew so much attention. This blog is intended to give you the high-level view of how we created the demo and provide some ideas for your own VSAN explorations. We documented other information such as node configurations, VSAN observer settings, and fio test workloads but didn’t provide it here for brevity’s sake. We’d love to hear comments and questions from anyone who wants to know more; post your comments below.
Our primary goal was to demonstrate best-in-class VSAN performance and show how that compared to a standard VSAN configured with SAS HDDs. One of the most interesting aspects of our configuration was that our M500 client SSDs were actually less expensive than the SAS 10K HDDs.
