1606 Extension SAN Switch and DC Dir Switch MP Extension Blade fabric rules This section describes the fabric rules for the 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade, and other factors you should consider when building B-series fabrics with Fibre Channel routing enabled. These fabric rules apply to SANs that include the same operating systems and storage products as the B-series switches (see "Operating systems and storage products" on page 107). See "B-series 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade" on page 312 for information about configuring the 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade for FCIP. Table 30 describes the rules for creating fabrics with Fibre Channel routing using the 1606 Extension SAN Switch, and the DC Dir Switch MP Extension Blade. Table 30 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade fabric rules Rule nl number Description The DC Dir Switch MP Extension Blade supports only the DC SAN Backbone Director and DC04 1 SAN Director. The maximum number of DC Dir Switch MP Extension Blades per DC SAN Backbone Director or DC04 SAN Director is two. 2 All configurations must use the default setting for R_A_TOV (10,000 seconds) and E_D_TOV (2,000 seconds). Devices connected to edge fabrics can be routed through an LSAN to a backbone fabric. 3 Note: Edge fabric to backbone fabric routing is supported using the 1606 Extension SAN Switch, DC Dir Switch MP Extension Blade, 400 MP Router, and MP Router Blade. It is not supported if an MP Router is configured in the backbone. 4 Direct connection of devices to the 1606 Extension SAN Switch or DC Dir Switch MP Extension Blade Fibre Channel ports (F_Port, FL_Port) is supported. 5 Fibre Channel server boot through the 1606 Extension SAN Switch or the DC Dir Switch MP Extension Blade is not supported. 6 Each 1606 Extension SAN Switch or DC Dir Switch MP Extension Blade can attach to one backbone fabric only; multiple routers can attach to the same backbone fabric. If a DC Dir Switch MP Extension Blade has a port configured as an EX_Port, then the blade Fibre 7 Channel ports, the Fibre Channel ports on the director containing the blade, and all 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. 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: • F_Port, FL_Port, E_Port (Fibre Channel switching) 9 • F_Port, FL_Port, EX_Port (Fibre Channel switching and Fibre Channel routing) • F_Port, FL_Port, VE_Port, VEX_Port (Fibre Channel switching and FCIP) • VE_Port, VEX_Port (Fibre Channel routing and FCIP) Note: VEX_Ports and EX_Ports cannot be connected to the same edge fabric. VEX_Ports are not supported on the DC Dir MP Extension Blade with firmware 6.3.0. 112 B-series switches and fabric rules
