UCS fabric extenders vs fabric interconnect

[yasir.ilyas]

Hi,

So my question is pretty  basic. The C series servers  act independently and can be managed by fabric interconnects does  that  mean  they  have  built  in fabric extenders on board  that  connect  behind  to  FIs? so B  series  they have  to be inserted  in UCS  chassis  which means they dont have  fabric  extender built in so The UCS  chassis  has extenders that  connect  to FI, is my  understanding  correct?

Thanks

UCS B is chasis, so it got simple Layer 2 switch on the back as FEX (bumb module) to connect back to FI

UCS C Standalone 1 U or 2 U box which got on board Ethernet, you can directly connec to sweitch (parent ).

NONe of the above has build in Fabric Inter connect.
