Not content with pulling disks and SSDs out of nodes, I also did some testing of powering off a node. I used a small cluster, two SimpliVity nodes, with 80 workload VMs. At the start, the VMs were split between the two nodes. Then I powered off one node using it’s built-in IPMI management controller. As you would hope, vSphere HA did its job and after a few minutes all the VMs were running on the one surviving node.
I’ve been doing a lot of work with SimpliVity and wanted to share a few videos of what happens when things go wrong with the hardware in their hyperconverged platform. This video looks at the results of hard disk and SSD failure in a SimpliVity node. A cluster running 120 VMs had no outage with two hard disks and one SSD failed.
Steven and I talk about some of what he learned deploying vMSC with HP 3Par storage.
We look at what vSphere Metro Storage Cluster is and how Steven has implemented it.
