Zoning database size and zone merging
Table 61
presents zoning database size limitations for various Fabric OS release versions. The maximum
size of a zone database is the upper limit for the defined configuration. It is determined by the amount of
flash memory available for storing the defined configuration.
Before linking two switches together, it is important that you know the zone database limit of adjacent
switches. For example, when switches running Fabric OS 3.2, 4.4.0, or 5.1.0 discover that the zone merge
database is larger than its pre-determined zone database size limit, they issue a reject notification before
symmetrically segmenting their own ends of the ISL, thereby preventing the new switch from joining the
fabric.
NOTE:
Fabric OS 5.2.0 and later support a zoning database size of 1 MB. To support a 1 MB zoning
database, the entire fabric must be upgraded to 5.2.0 or later. If any pre-5.2.0 switches are part of the
fabric, the maximum zone database size is 256 KB. If the zoning database size exceeds 256 KB, switches
not upgraded to Fabric OS 5.2.0 or later are segmented out of the fabric. Use the
cfgSize
command to
display the zoning database size.
Symmetrical segmentation occurs when both ends of an ISL are shut down. Subsequently, no frames are
exchanged between those two switches.
Asymmetrical 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. The following tables provide the expected behavior based on different database sizes after a
zone merge is specified.
