Notice that all these servers provide a rather modest storage system. In most applications, shared storage will be necessary to avoid a storage bottleneck and to provide the necessary redundancy.

VMware recognizes the problem as being a reporting issue between the BIOS and ESX. It should be fixed by U1 of ESX4.More info here.
