HP BladeSystem c-Class SAN connectivity technology brief

Figure 5 shows the mapping of the FC connectivity options for the c7000 enclosure. Figure 5
illustrates the maximum FC connection capability of the c7000 enclosure. In practice, server blades
can support a mix of mezzanine cards of different interface types (FC, Ethernet, or InfiniBand)
simultaneously within the enclosure. Having two or more FC HBA mezzanine cards on each server
blade offers redundancy and enhanced throughput.

NOTE:
The mezzanine slot fabric designation of all blades in a given
enclosure must be consistent. For example, the mezzanine card
installed in slot 1 of each blade must be the same technology (FC,
Ethernet, or InfiniBand) to work with the FC, Ethernet, or InfiniBand
interconnect modules in interconnect bays 3 and 4. However, it is
not mandatory that every server blade include a mezzanine card if
a connection to a fabric is not required by a server. Technical
