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”
(page 102). For information about configuring the 1606 Extension SAN Switch and DC Dir Switch
MP Extension Blade for FCIP, see “B-series 1606 Extension SAN Switch and DC Dir Switch MP
Extension Blade” (page 285).
Table 32 (page 107) describes the rules for creating fabrics with Fibre Channel routing using the
1606 Extension SAN Switch and the DC Dir Switch MP Extension Blade.

Description
1
The DC Dir Switch MP Extension Blade supports only the HP SN8000B 8-Slot SAN Backbone Director,
HP SN8000B 4-Slot SAN Director, DC SAN Backbone Director and DC04 SAN Director. The maximum
number of DC Dir Switch MP Extension Blades per HP SN8000B SAN Directors (both 4 and 8-slot) is
four. 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 milliseconds) and E_D_TOV (2,000
milliseconds).
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 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.
7
If a DC Dir Switch MP Extension Blade has a port configured as an EX_Port, then the blade Fibre 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 512 devices.
9
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)
• 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.
10
FCIP is supported between pairs of 1606 Extension SAN Switches and DC Dir Switch MP Extension
Blades, or between a 1606 Extension SAN Switch and a DC Dir Switch MP Extension Blade. FCIP is not
supported in between the 1606 Extension SAN Switch or DC Dir Switch MP Extension Blade and the MP
Router, 400 MP Router, or MP Router Blade. See “B-series 1606 Extension SAN Switch and DC Dir Switch
MP Extension Blade” (page 285).
