LSAN zone binding
LSAN zone binding is an optional, advanced feature that increases the scalability envelope for very
large metaSANs.
Without LSAN zone binding, every FC router in the backbone fabric maintains the entire LSAN zone
and device state database. The size of this database limits the number of FC routers and devices you
can have.
With LSAN zone binding, each FC router in the backbone fabric stores only the LSAN zone entries of
the remote edge fabrics that can access its local edge fabrics. The LSAN zone limit supported in the
backbone fabric is not limited by the capability of one FC router. In addition, due to the lower LSAN
count, the CPU consumption by the FC router is lower. If you configure the metaSAN such that the
backbone fabric has two groups of FC routers and there is no LSAN zone sharing and device access
between the two groups, the number of FC routers and devices supported in the backbone fabric can
be higher.
The following figure shows a sample metaSAN with four FC routers in the backbone fabric. Without
LSAN zone binding, each FC router in the backbone fabric would store information about LSAN zones
1, 2, 3, and 4.
