I am running a brand new install of vCenter with two brand new installs of ESXi 4.1 connected to it. I am running the ESXi servers on Dell PowerEdge 2950s. I have tired the Dell customized version and the vanilla vmware version of ESXi. My vCenter Host is Windows 2008 R2.
In vCenter, on both ESXi servers, no matter which version of ESXi I run, I get the error "Communication error with the server" when I click on the hardware status tab. No data shows up at all in the hardware status tab.
Dell's only suggestion was to upgrade the firmware/BIOS on the servers. I did that and it did not help.
Does anyone have any suggestions or ideas what would cause this?
