HP 4Gb Pass-Thru Module for the HP c-Class BladeSystem The HP 4Gb Pass-Thru Module provides transparent, 1:1 port connectivity (16 internal/16 external) between HBA mezzanine ports and external SAN devices or switches. The module, which has 16 ports with short-wave 4-Gb SFP transceivers, provides a solution for connecting c-Class FC HBAs to a local SAN. It is suitable for installations where the SAN is in close proximity and the amount of cabling is not a major concern. Cisco MDS 9124e Fabric Switch for HP c-Class BladeSystem The Cisco MDS 9124e Fabric Switch installs directly into c-Class enclosures. 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. The Cisco switch provides the following additional capabilities: • Traffic management - Simplified deployment with virtual output queuing and Fastest Shortest Path First (FSPF) technology optimizes the fabric performance. • Virtual SAN (VSAN) support - Up to 16 VSANs per switch can be managed as independent fabrics for more efficiency and lower cost through shared use, and for increased security through isolation of devices on the same physical SAN. Port mapping of server blade FC HBA mezzanine cards The mapping of server blade communications ports is hard-wired into the signal midplane of c-Class enclosures. All c-Class server blades include two or four embedded network interface controllers (NICs) connected by the midplane to interconnect bays 1 and 2, which are dedicated for Ethernet modules. The fabric designation of interconnect bays 3 through 8 is dependent upon the optional mezzanine cards installed on the server blades. Figure 5 shows the mapping of FC options for the HP BladeSystem c7000 enclosure. NOTE: Mezzanine cards for c-Class server blades are defined as being 1x, 2x, or 4x port types, with nx referring to the number of interconnect lines per port provided by the controller. FC HBA mezzanine cards are 1x port type. 7

The mapping of server blade communications ports is hard-wired into the signal midplane of c-Class
enclosures. All c-Class server blades include two or four embedded network interface controllers
(NICs) connected by the midplane to interconnect bays 1 and 2, which are dedicated for Ethernet

NOTE:
Mezzanine cards for c-Class server blades are defined as being
1x, 2x, or 4x port types, with
n
x referring to the number of
interconnect lines per port provided by the controller. FC HBA
mezzanine cards are 1x port type.
