Brocade Adapters Installation and Reference Manual 17953-1002144-01Converged Network Adapters 5Converged Network AdaptersTwo types of CNAs are available:• Stand-up adapter• Mezzanine adapterThe Brocade stand-up CNAs are low-profile MD2 form factor PCI Express (PCIe) cards, measuring6.60 in. by 2.71 in. (16.77 cm by 6.89 cm). CNAs are shipped with a low-profile bracket installedand a standard bracket included for mounting in your host system. Table 18 lists the two brackettypes and dimensions.Mezzanine CNAs are smaller than stand-up modules. For example, the Brocade 1007 adapter is anIBM compact form factor horizontal (CFFh) adapter measuring approximately 4.9 in. (12.44 cm) by0.5 in. (1.27 cm) by 6.3 in. (16 cm). Mezzanine adapters mount on blade servers that install insupported blade system enclosures. Refer to the “Server blades and blade system enclosures(mezzanine adapters)” on page 11 for references to CNA compatibility information. Note thatmezzanine CNAs do not have external port connectors with optics such as stand-up CNAs, butinternal ports that connect to switch and I/O modules installed in the blade system enclosurethrough high-speed links in the internal enclosure backplane.PCI Express interfaceInstall Brocade stand-up CNAs in PCI Express (PCIe) computer systems with an Industry StandardArchitecture/Extended Industry Standard Architecture (ISA/EISA) bracket type. Install the Brocademezzanine CNAs in supported server blades that install in supported blade system enclosures.On-board flash memory provides BIOS support over the PCIe bus.The CNA is designed to operate on an x8 lane DMA bus master at 250 GMhz. Operation cannegotiate from x8 to x4, x2, and x1 lanes. Following are transfer and data rate specifications foroperation in PCIe Gen 2 and Gen 1 connectors:• PCIe Gen 2 connector. Transfer rate of 5 Gigatransfers per second (GT/s) per lane. Data rate of500 MBps per lane.• PCIe Gen 1 connector. Transfer rate of 2.5 GT/s per lane. Data rate of 250 MBps per lane.Power Consumptionadapter and optics9 W typical with SFP running 16 Gbps trafficOperating Voltage 12VTABLE 17 Environmental and power requirements (continued)Property RequirementTABLE 18 CNA mounting bracketsBracket Type DimensionsLow Profile 73 in. by 3.15 in.
