Couple of questions about the 10GbE mezz cards for this chassis:
- Is there a difference in Dell part numbers between TCK99 and X53DF or is one just a revision that launched with a newer chassis, e.g. C6220?
- Anyone know which chipsets these are using? I was suspecting it might have been Intel 82599 for one of them but I think the X53DF might be X520-DA2.
