.Part 2 Fabric Infrastructure Rules HP SAN Design Reference Guide 785352-001
XPath OS compatibility
Table 20 (page 94) through Table 22 (page 95) list the B-series switches and firmware versions
that are supported in a SAN with the MP Router XPath OS.
Scalability rules
Table 35 (page 118) lists the scalability rules for Meta SANs using the MP Router.
The following terms describe MP Router scalability:
• Front phantom domains—Individual EX_Port connections from the MP Router to the edge
fabrics.
• Translate phantom domains—Assigned to each remote fabric connected to an MP Router.
There is one unique translate domain for each fabric, regardless of how many EX_Ports are
connected to the fabric.
• Backbone fabric—The MP Router backbone fabric consists of at least one MP Router and
includes all MP Routers and B-series switches connected to the MP Router via E_Ports.
• Edge fabric—A fabric that is attached to an EX_Port on an MP Router.

Edge fabric scalability
24Maximum number of front domains (number of EX_Ports) per edge fabric
Domains
1
33Maximum number of translate domains (number of remote fabrics) per edge fabric
34Maximum number of real domains (local switches) per edge fabric
80
Maximum 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.
1,280
Maximum 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

Maximum number of entries per LSAN zone

Note: LSAN zones support WWN-based zoning only.

For more information, see Figure 56 (page 119).
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 33 (page 112).
