Description
Rule
number
• FCFW does not work in FICON environments.
• FCFW flows may be routed to another 400 MPR or MP Router blade on the FC network. This 400 MPR or MP
Router blade may have active FCIP tunnels over an IP network. FCFW flows may be passed through the FCIP
tunnel, but only if the FCIP FastWrite option is disabled on the tunnel.
• FCFW does not support loop device configurations for more than one device.
For more information, see the Fabric OS FCIP Administrator's Guide, V6.3.0 (or later).
For redundancy, HP recommends using a minimum of two EX_Ports (router IFLs) for each fabric connected to an 400
MP Router or MP Router Blade. The number of EX_Ports required is based on the performance requirements for all
devices shared by fabrics through the router.

• For initial settings, calculate the number of EX_Ports using a 5:1 ratio of standard ISLs or switch device ports to
router EX_Port IFLs. Monitor port performance to determine if this ratio is acceptable based on usage. Use the
portperfshow command to monitor router port performance.
• For very high bandwidth requirements and applications, use a ratio of 3:1 or 1:1.

Scalability rules
Table 33 (page 112) lists the scalability rules for Meta SANs using integrated Fibre Channel routing,
the 400 MP Router, and the MP Router Blade. For MP Router scalability rules, see “Scalability
rules” (page 118). For configurations with an MP Router and a 400 MP Router or MP Router Blade,
apply the rules in Table 33 (page 112).
The following terms describe MP Router scalability:
• Front phantom domains—All EX_Ports on a Fibre Channel router that are connected to the
same edge fabric are presented as a single front phantom domain.
• Translate phantom domains—Assigned to each remote fabric connected to a 400 MP Router
or MP Router Blade. Each fabric has one unique translate domain, regardless of how many
EX_Ports are connected to the fabric.
• Backbone fabric—The 400 MP Router or MP Router Blade backbone fabric consists of at least
one 400 MP Router or MP Router Blade and includes all MP Routers and B-series switches
connected via E_Port to the 400 MP Router or MP Router Blades. When you install an MP
Router Blade in a 4/256 SAN Director, all devices connected to the SAN Director Fibre
Channel ports are part of the backbone fabric.
• Edge fabric—A fabric that is attached to an EX_Port on a 400 MP Router or MP Router Blade.
