Host Bus Adapters 5 TABLE 24 Property Environmental and power requirements for Brocade 1741 CNA mezzanine card Requirement Operating Voltage Dimensions Per PCIe 2.0 specifications 3.6 in. by 1.5 in. by 3.3 in. (9.144 cm by 3.81 cm by 8.382 cm) The Brocade 1741 mezzanine adapter conforms to environmental and power specifications for the supported server blades and blade system enclosures where they install. Refer to the documentation provided for these products for more information. Also refer to "Server blades and blade system enclosures (mezzanine adapters)" on page 11.for references to CNA compatibility information. Host Bus Adapters Two types of HBAs are available: • Stand-up • Mezzanine The stand-up HBAs are low-profile MD2 form factor PCI Express (PCIe) cards, measuring 6.6 in. by 2.714 in. (16.765 cm by 6.89 cm), that install in standard host computer systems. HBAs are shipped with a low-profile bracket installed and a standard bracket included for mounting in your host system). These HBAs contain either one or two external ports for connecting to Fibre Channel switches via fiber optic cable. Table 25 provides the dimensions for the two bracket types. TABLE 25 Mounting brackets for stand-up HBAs Bracket Type Dimensions Low Profile Standard 1.84 cm by 8.01 cm (73 in. by 3.15 in.) 1.84 cm by 12.08 cm (73 in. by 4.76 in.) The mezzanine type HBAs are smaller cards. For example, the Brocade 804 adapter measures approximately 4 in. by 4.5 in. (10.16 cm by 11.43 cm). Mezzanine adapters mount on server blades that install in supported blade system enclosures. Refer to "Hardware compatibility" on page 15 for references to HBA compatibility information. Note that mezzanine adapters do not have external port connectors with optics such as stand-up HBAs, but internal ports that connect to the switch and interconnect modules installed in the enclosure through high-speed links in the internal enclosure backplane. PCI Express interface Install Brocade stand-up HBAs in PCI Express computer systems with an Industry Standard Architecture/Extended Industry Standard Architecture (ISA/EISA) bracket type. Install Brocade mezzanine HBAs in supported blade servers that install in supported blade system enclosures. Multiple HBAs may be mounted in connectors located at different locations in the blade server.
