An important decision to take when planning an ESXi deployment is the choice of the hardware platform of the server. ESXi doesn't support all the hardware available on the market (storage controllers, NICs, and so on) and has some restrictions that can prevent the successful installation of the hypervisor.
Only tested and supported hardware ensures that your ESXi can be installed without any problem and can operate as expected. Before purchasing the hardware for your server, it is strongly recommended you verify whether ESXi supports the chosen hardware platform.
To check for hardware compatibility, you can refer to the VMware Compatibility Guide available at https://www.vmware.com/resources/compatibility/
