VMware vSphere 4.0 on a Dell 2850 Irvandale CPU. I can’t believe it!

We are in the process of readying an old Dell 2850 for a DR CO-LO site. Before I send it out, I wanted to test it’s limitations so when we upgrade to a 64 bit guest OS or want to run the newest version of ESX we don’t find out by surprise that it won’t work. I know our server won’t run a 64 bit guest. That’s a given. Despite that I wanted to see if I could leverage ESX 4.0’s new feature set.

So step one was to install a DVD iso to a server with a CD optical drive. The easiest way I found is to use a 1Gb USB stick.

Here are the instructions I used to download esx-DVD-4.0.0-164009.iso a 797mb iso and copy it to a USB stick.

Once your media is ready you will need to change your Dell 2850 to boot to USB. I had to look it up. Here are the instructions.

Once you boot to the USB it’s a “click next” install to ESX 4.0 running on a DEll 2850.

I’m running bios A4.

Roger’s Take:

I find this Interesting because the Server is not on compatibility list, it has Older hardware, wont run a 64 guest, but it runs vSphere. None of my 64bit IBM Servers that book a 64bit OS will run vSphere.
