Converged Network Adapters 5 TABLE 17 Property Environmental and power requirements (continued) Requirement Power Consumption adapter and optics 9 W typical with SFP running 16 Gbps traffic Operating Voltage 12V Converged Network Adapters Two types of CNAs are available: • Stand-up adapter • Mezzanine adapter The Brocade stand-up CNAs are low-profile MD2 form factor PCI Express (PCIe) cards, measuring 6.60 in. by 2.71 in. (16.77 cm by 6.89 cm). CNAs are shipped with a low-profile bracket installed and a standard bracket included for mounting in your host system. Table 18 lists the two bracket types and dimensions. TABLE 18 CNA mounting brackets Bracket Type Dimensions Low Profile Standard 73 in. by 3.15 in. (1.84 cm by 8.01 cm) 73 in. by 3.15 in. (1.84 cm by 12.08 cm) Mezzanine CNAs are smaller than stand-up modules. For example, the Brocade 1007 adapter is an IBM compact form factor horizontal (CFFh) adapter measuring approximately 4.9 in. (12.44 cm) by 0.5 in. (1.27 cm) by 6.3 in. (16 cm). Mezzanine adapters mount on blade servers that install in supported blade system enclosures. Refer to the "Server blades and blade system enclosures (mezzanine adapters)" on page 11 for references to CNA compatibility information. Note that mezzanine CNAs do not have external port connectors with optics such as stand-up CNAs, but internal ports that connect to switch and I/O modules installed in the blade system enclosure through high-speed links in the internal enclosure backplane. PCI Express interface Install Brocade stand-up CNAs in PCI Express (PCIe) computer systems with an Industry Standard Architecture/Extended Industry Standard Architecture (ISA/EISA) bracket type. Install the Brocade mezzanine 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 can negotiate from x8 to x4, x2, and x1 lanes. Following are transfer and data rate specifications for operation 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 of 500 MBps per lane. • PCIe Gen 1 connector. Transfer rate of 2.5 GT/s per lane. Data rate of 250 MBps per lane. Brocade Adapters Installation and Reference Manual 179 53-1002144-01
