Fibre Channel routing, 400 MP Router, and MP Router Blade fabric rules This section describes the fabric rules for 8 Gb/s switches with license-enabled integrated Fibre Channel routing, the 400 MP Router, and the MP Router Blade, and other factors you should consider when building B-series fabrics that contain Fibre Channel routing. The fabric rules for Fibre Channel routing apply to SANs that include the same operating system and storage products as the B-series switches (see "Operating systems and storage products" on page 107). See "B-series 400 MP Router and MP Router Blade" on page 316 for information about configuring MP Routers for FCIP. Table 31 describes the rules for creating fabrics with Fibre Channel routing using 8 Gb/s switches, 400 MP Routers, and MP Router Blades. Table 31 Integrated Fibre Channel routing, 400 MP Router, and MP Router Blade fabric rules Rule nl number Description 1 The MP Router Blade supports only the DC SAN Backbone Director, DC04 SAN Director, and SAN Director 4/256. The maximum number of MP Router Blades per DC SAN Backbone Director is four; the maximum number of MP Router Blades per DC04 SAN Director is four; the maximum number of MP Router Blades per SAN Director 4/256 is two. 2 All configurations must use the default setting for R_A_TOV (10,000 seconds) and E_D_TOV (2,000 seconds). 3 Devices connected to edge fabrics can be routed through an LSAN to a backbone fabric. Note: Edge fabric-to-backbone fabric routing is supported using the 400 MP Router and MP Router Blade only. It is not supported if an MP Router is configured in the backbone. 4 Direct connection of devices to the 400 MP Router or MP Router Blade Fibre Channel ports (F_Port, FL_Port) is supported. 5 Fibre Channel server boot through the 400 MP Router or MP Router Blade is not supported. 6 Each 400 MP Router or MP Router Blade can only attach to one backbone fabric, multiple routers can attach to the same backbone fabric. 7 If an MP Router Blade has any port configured as an EX_Port, then the blade Fibre Channel ports, all Fibre Channel ports in the director the blade is in, and all other switches connected to the director using an E_Port are part of the backbone fabric. 8 A backbone fabric supports a maximum of 256 devices. 9 For the 400 MP Router and MP Router Blade, you can configure a Fibre Channel port as an F_Port, FL_Port, E_Port, or EX_Port (Fibre Channel routing), and configure a GbE port as a VE_Port (FCIP) or VEX_Port (FCIP with Fibre Channel routing). Traffic switching is supported between the following port types: • Fibre Channel switching (F_Port, FL_Port, E_Port) • Fibre Channel switching and Fibre Channel routing (F_Port, FL_Port, EX_Port) • Fibre Channel switching and FCIP (F_Port, FL_Port, VE_Port, VEX_Port) • Fibre Channel routing and FCIP (VE_Port, VEX_Port) Note: VEX_Ports and EX_Ports cannot be connected to the same edge fabric. 10 FCIP is supported between pairs of 400 MP Routers, MP Router Blades, or between a 400 MP Router and MP Router Blade. FCIP is not supported between an MP Router and either a 400 MP Router or MP Router Blade. See "B-series 400 MP Router and MP Router Blade" on page 316. 116 B-series switches and fabric rules
