Figure 41 LSAN zone binding
After you set up LSAN zone binding, each FC router stores information about only those LSAN zones that
access its local edge fabrics. Table 71 shows what LSAN information is stored in each FC router before
and after LSAN zone binding is in effect.
To summarize:
• Without LSAN zone binding, the maximum number of LSAN devices is 10,000.
• With LSAN zone binding, the metaSAN can import more than 10,000 devices and the backbone
fabric can support more FC routers.
• With LSAN zone binding, CPU consumption by an FC router is lower.
How LSAN zone binding works
LSAN zone binding uses an FC router matrix, which specifies pairs of FC routers in the backbone fabric
that can access each other, and an LSAN fabric matrix, which specifies pairs of edge fabrics that can
access each other.
Set up LSAN zone binding using the fcrLsanMatrix command. This command has two options: -fcr
and -lsan. The -fcr option is for creating and updating the FC router matrix, and the -lsan option is used for
