Connection blades within one fabric must have the same technology, i.e.
either Ethernet or Fibre Channel or Infiniband.
When installing the different types of mezzanine cards, make sure that
the slots in fabrics 2, 3 and 4 of the system unit are fitted with the
appropriate connection blades.
The following rules apply for fitting the mezzanine card slots of the server
blades:
●
If a 1 Gb Ethernet mezzanine card is installed in slot 1 of a server blade, at
least one 1 Gb Ethernet connection blade must be installed in fabric 2 of the
system unit.
●
If a 10 Gb Ethernet mezzanine card or a 10Gb CNA mezzanine card is
installed in slot 1 of a server blade, at least one 10 Gb Ethernet connection
blade must be installed in fabric 2 of the system unit.
