Table 34 MP Router scalability rules
Edge fabric scalability
24Maximum number of front domains (number of EX_Ports) per edge fabricDomains
(see Figure 46)
33Maximum number of translate domains (number of remote fabrics) per edge fabric
34Maximum number of real domains (local switches) per edge fabric
80Maximum number of domains per edge fabric (real domains + front domains + translate
domains)
Note: The total number of domains in the first three rows must not exceed 80.
1,280Maximum number of local and remote devices per edge fabric. (For edge fabrics with more
than 600 devices, 4.2.0c or later is required for all switches in the fabric when using the
MP Router.)
Devices (user ports)
1,000Maximum number of imported devices per edge fabric
LSAN zone scalability
200Maximum number of entries per LSAN zone
Note: LSAN zones support WWN-based zoning only.

Meta SAN scalability
34Maximum number of edge fabrics connected in a Meta SANEdge fabrics
12,800Maximum number of total ports per Meta SANMeta SAN
14Maximum number of MP Routers per Meta SANRouters
10,000Maximum number of LSAN device entries (proxy devices) per Meta SANLSAN
1,000Maximum number of LSAN zones per Meta SAN
Hop count scalability
12Maximum number of hops between switches (including routers) in a Meta SAN (Figure 45)Hop count
NOTE:
For configurations that have an MP Router with a 400 MP Router or MP Router Blade in the same
Meta SAN, apply the 400 MP Router and MP Router Blade scalability rules
(lowest-common-denominator limits apply). See Table 32 on page 119.
MP Router hop count
The MP Router counts the same as a Fibre Channel switch is counted with respect to 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.
