HI Gurus
I am very new to UCS and I am not even close to be as knowledgeable as you gurus are , so go easy on me.
Here is my problem and I hope you gurus can help.
I have a blade that shows 8 DCE interface , and I think this is the reason why this particular Host is on 40GE, now all my other blades on the same chassis has 4 DCE interface creating a set of 20GE, I really need to know.
I hope I made sense for any of you.
Thanks a bunch

Yes, this all depends on the hardware configuration of your blade, specially the I/O adaptor config. Port-channel between I/O adaptor and IOM are done automatically and cannot be changed.
Not to my knowledge. It's autoconfigured and cannot be changed.
eg. if you have a blade with 2 I/O adaptors, one VIC-1240, one VIC-1280, plus a IOM 2208.
you see 4 DCE interfaces for VIC-1240, and 4 for VIC-1280; and the 4 are configured as a 2 link port-channel to fabric A resp. B.
in the case of a VIC-140 and a extender, you would see 8 DCE interfaces; 4 in a port-channel to each fabric.
This has been discussed before
