[. . . ] Integrating the switch within the enclosure simplifies SAN network deployment by reducing the costs of cabling, SFP transceivers, and installation time. Cost is further reduced by sharing intelligent power and cooling resources provided by the enclosure. The Cisco 4-Gb SAN Switch includes Cisco Fabric Manager for integrated, comprehensive SAN management including fabric configuration, verification, and monitoring. Also included is a broad range of integration tools, including the Cisco MDS 9000 family Command Line Interface (CLI) and industry-standard third-party SNMP and SMI-S application programming interfaces (APIs). This switch is available in 12-port and 24-port models that include two and four short-wave 4-Gb SFP transceivers respectively. A 12-port upgrade license is available for the 12-port model. Additional capabilities include: · Traffic management ­ Simplified deployment with virtual output queuing and Fastest Shortest Path First (FSPF) technology optimizes the fabric performance. 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. The HP BladeSystem c-Class system includes the HP Onboard Administrator for BladeSystem. This Onboard Administrator provides run-time management and configuration of all components in the enclosure. When the system is booted, the Onboard Administrator of the enclosure checks the configuration of server blades and interconnect modules for errors. The system status, including interconnect data, appears on the HP Insight Display at the front of the enclosure. Figure 5 shows screen shots from the HP Insight Display of the c7000 enclosure. A display highlighted in green indicates no errors; a display highlighted in amber indicates that an error has been detected. Figure 5.

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 capability is required.

HP recommends the use of redundant SANs. To provide redundancy for FC HBA mezzanine cards: · One or more server blades with a dual-port FC HBA card require two FC interconnect modules. · One or more server blades with two dual-port FC HBA cards require four interconnect modules. [. . . ] Two switches are required for redundant path support. SAN Management controls the embedded SAN switches and also manages SAN resource access and security. Each server HBA port can see any or all of the eight external FC ports on the SAN Switch Figure 9.
