HP StorageWorks 2.128 SAN Director Switch - Manual (Page 189)

Fabric OS 5.x administrator guide 189
Symmetrical segmentation occurs when both ends of an ISL are shut down. Subsequently, no frames are
exchanged between the two switches.
Asymemetrical segmentation not only prevents frames from being exchanged between switches, but also
causes routing inconsistencies.
The best way to avoid either type of segmentation is to know the zone database size limit of adjacent
switches. Table 36 through Table 39 provide the expected behavior based on different database sizes
after a zone merge is specified.
Table 37 Resulting database size: 96K to 128K
Table 36 Resulting database size: 0 to 96K
