In this article, I’ll show you how to check a VMware ESXi Host Version and build number using the all new Sphere Web Client.
With the release of ESXi 6.5 the Windows “Fat Client” Is no longer available and all administration Is now done using the Web Interface.
Note: If you don’t have the Web Client and you are using ESXi 5, 5.5 or 6, you can use the Windows “Fat Client” to check the version using the following article: How To Check VMware ESX or ESXi Version and Build Number
