LSAN zone configuration
24
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 81 on page 599 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.
FIGURE 81 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 85 shows what LSAN information is stored in each FC
router before and after LSAN zone binding is in effect.
