LSAN zone binding
LSAN zone binding is an optional, advanced feature that increases the scalability envelope for very
large metaSANs.
NOTE
LSAN zone binding is supported only on FC routers with Fabric OS v5.3.0 and later. The FC router
matrix feature is supported only on FC routers with Fabric OS v6.1.0 and later.
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.
Figure 75 on page 486 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.
