1,UCS not only refers to the server of B or the server of C, from FI to b/c the whole set is called UCS, Unified Computing System (note: not called server)
2,FI is not a fibre switch, his earlier version of the equivalentof 55XX, now version equivalent to 93XX, the difference lies in the integrated UCSM management chip
3, with the UCSM management chip, you can manage the GUI,fi through the in-band channel to connect chassic IOM, so you can manage including CHASSIS includes all the resources of IOM BLADE.
