The VMware ESXi download page has two new downloads, ESXi installable with Dell and IBM customizaions:
VMware ESXi 4.0 with Dell Customization
Version 4.0.0 | 164009 - 07/16/09 348 MB ISO Image for ESXi Installable that includes Dell customization.
VMware ESXi 4.0 with IBM Customization
Version 4.0.0 | 164009 - 07/16/09 348 MB ISO Image for ESXi 4.0 Installable that includes IBM customization for use on supported IBM server platforms.
I can't find any information detailing what 'customization' is included in either install. Is it management (OpenManage stand alone), drivers???
I suppose I'll have to install it on one of the m600 servers and find out.
Update: I got a response from a Dell rep on the Power Edge mailing list "Vmware ESXi 4.0 includes Dell OpenManage as well apart from drivers."
