about configuring MP Routers for FCIP, see “B-series 400 MP Router and MP Router Blade”
(page 290).
Table 32 (page 111) describes the rules for creating fabrics with Fibre Channel routing using 8
Gb/s switches, 400 MP Routers, and MP Router Blades.
Table 32 Integrated Fibre Channel routing, 400 MP Router, and MP Router Blade fabric rules
Description
Rule
number
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
1
Router Blades per DC04 SAN Director is four; the maximum number of MP Router Blades per SAN Director 4/256
is two.
All configurations must use the default setting for R_A_TOV (10,000 milliseconds) and E_D_TOV (2,000 milliseconds).2
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 400 MP Router and MP Router Blade only. It is
not supported if an MP Router is configured in the backbone.
Direct connection of devices to the 400 MP Router or MP Router Blade Fibre Channel ports (F_Port, FL_Port) is
supported.
4
Fibre Channel server boot through the 400 MP Router or MP Router Blade is not supported.5
Each 400 MP Router or MP Router Blade can only attach to one backbone fabric; multiple routers can attach to the
same backbone fabric.
6
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.
7
A backbone fabric supports a maximum of 256 devices.8
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:
9
• 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.
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” (page 290).
10
FCIP is supported with IPsec data encryption. This requires a minimum firmware version of 5.2.0a. IPsec is supported
with HP P6000 Continuous Access and HP P9000 (XP) Continuous Access.
11
Note: IPsec and FCIP FastWrite are mutually exclusive and cannot be configured simultaneously.
FCIP FastWrite support:
• FCIP is supported with FCIP FastWrite SCSI write acceleration. This requires a minimum firmware version of 5.2.0a.
For firmware version 6.3.x, version 6.3.0c (or later) is required for FCIP FastWrite. FCIP FastWrite is supported
with HP P9000 (XP) Continuous Access and is not supported with HP P6000 Continuous Access.
Note: FCIP FastWrite and IPsec are mutually exclusive and cannot be configured simultaneously.
12
Fibre Channel FastWrite support:13
• FC FastWrite is supported starting with Fabric OS 5.3.0. However, the following rules apply while configuring
FCFW:
• FCFW disables the local Ethernet ports (ge0 and ge1), making it impossible to configure FCFW and FCIP tunnels
on the same 400 MPR or the MP Router blade.
