So you have to install the hypervisor on DELL R720 server. Let’s have a look on VMware’s HCL:






Checked! You boot the server from a DVD and you are warmly welcomed with the following message:






Really? The network card is Broadcom 5720 QP 1Gb Network Daughter Card. Here it is:






Let’s check DELL website. A quick search and here‘s the solution. So what DELL says is: The reason for this is because the VMware native ESXi 5.0 image does not contain the required version(s) of network drivers for Network Daughter Cards (NDC) or Network adapters used in Dell 12G Servers.

Fortunately a modified ESXi image is available on so no need to play with the Image Builder.

    If a hardware is on HCL, it doesn’t automatically mean its included in the image ;)

    Lesson learned: Always use vendor branded ISO image, if available of course :)
