Re: ESXi 4 - working whitebox
Now this will work fine in ESXI 4.0, but im worried as the card is slightly larger than a regualr network card, and that it may not fit in a smaller case, please correct me if im wrong?
PCI-X card in a PCI slot will work if you can get it into the slot. PCI-X is a little longer and some MBs have components where the PCI-X card connector is located. Performance wise you will see a drop but it will most likely work just fine.
For expansion cards the general rule is:
"If you can get it in the socket, it will work" (however it may not work at maximum sustained performance).
Same for PCI-E X1 to PCI-E X4 or X8 or PCI-E X8 to X16 etc.
And Same for PCI to PCI-X
