FC SAN connectivity Figure 8 shows FC port connectivity in the c7000 enclosure for full-height and half-height server blades connecting to a SAN through FC interconnect modules. Figure 8.

To ensure high availability, each FC HBA mezzanine card is dual-ported, and each port is routed to a separate interconnect bay. For example, as indicated in Figure 6 and in Table 1, the ports on an HBA mezzanine card in slot 1 are routed to bays 3 and 4. Interconnect modules must be installed in pairs if redundancy is required.
