Scalability rules
Table 32 lists the scalability rules for Meta SANs using integrated Fibre Channel routing, the 1606
Extension SAN Switch, DC Dir Switch MP Extension Blade, 400 MP Router, and MP Router Blade.
See
Scalability rules on page 124 for MP Router scalability rules. For configurations with an MP Router
and a 400 MP Router or MP Router Blade, apply the rules in Table 32 .
The following terms describe 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade
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 1606 Extension
SAN Switch, DC Dir Switch MP Extension Blade, 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 1606 Extension SAN Switch or DC Dir Switch MP Extension Blade backbone
fabric consists of at least one 1606 Extension SAN Switch or DC Dir Switch MP Extension Blade,
and includes all MP Routers and B-series switches connected via E_Ports to the 1606 Extension
SAN Switch or DC Dir Switch MP Extension Blade. When you install a DC Dir Switch MP Extension
Blade in a DC SAN Backbone Director or DC04 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 1606 Extension SAN Switch or DC Dir
Switch MP Extension Blade.
1606 Extension SAN Switch and DC Dir Switch MP Extension Blade hop count
The 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade are counted in the same
way as a Fibre Channel switch when determining the fabric hop count (
Figure 45 ). Devices
communicating across fabrics through an MP Router must adhere to both the B-series 7-hop limit within
an edge fabric and the MP Router 12-hop limit .
1606 Extension SAN Switch and DC Dir Switch MP Extension Blade usage
Use a DC Dir Switch MP Extension Blade:
• If you want to add multiple fabrics to a Meta SAN, and one of those fabrics contains a DC SAN
Backbone Director or DC04 SAN Director with an available slot for a DC Dir Switch MP Extension
Blade
