connections to be implemented.
The following mezzanine cards are available for the server blade:
– 1 Gbit/s Ethernet mezzanine card with 4 ports
– 6 Gbit/s SAS HBA mezzanine card
– 6 Gbit/s SAS expander mezzanine card
– 8 Gbit/s fiber-channel mezzanine card with 2 ports
– 10 Gbit/s Ethernet mezzanine card with 2 ports
– 10 Gbit/s CNA mezzanine card with 2 ports
– 40-Gbit/s Infiniband mezzanine card with 2 ports
– 56-Gbit/s Infiniband mezzanine card with 2 ports

If a server blade is configured with one or two mezzanine cards, this does
not exclude other configurations for any of the other server blades in a
system unit.
If you want to install mezzanine cards in server blades, the system unit
must be fitted with the corresponding Fibre Channel, SAS, Infiniband
and/or Ethernet connection blades. You can find detailed information
about the equipping rules for connection blades in the operating manual
for the system unit.
