2204 > 1240, only 2 x 10Gb??

I read a very good article on TJs Thoughts regarding how UCS achieves 80Gb per Blade. Within this blog TJ has a diagram (see attached) of the internal 10Gb-KR connectivity between the various IOMs, through the backplane and finally to the mLOM and mezz via the system board. Diagram B show a 2204 > VIC1240 on an B200 M3.

My question is this; within this configuration if the mezz slot is not populated with the port-expander is this configuration really limited to 20Gb per blade (1x 10Gb-KR lane from each IOM)…….????

Or does the mezz slot come pre populated with a port-expander by default……?M3-blade+IOM.png

Here's the breakdown:

IOM-2208

B200M3 + VIC 1240 Only = Dual 2x 10Gbe

B200M3 + VIC 1240 + Expander = Dual 4x 10Gbe

IOM2204

B200M3 + VIC 1240 Only = Dual  1x 10Gbe

B200M3 + VIC 1240 + Expander = Dual 2x 10Gbe

The Port Expander is not a base option, it must be added.  The port Expander essentially doubles the available bandwidth (based on the IOM used).
