Advanced Zoning—The maximum zoning database size is as follows:
• If all switches in a fabric are using firmware 5.2x (or later), the database size must not exceed
1 MB.
• If the fabric contains 1 Gb/s switches with firmware 2.6.1x (or later), the database must not
exceed 96 KB.
• If the fabric contains 2 Gb/s or 4 Gb/s switches with firmware 3.2.x (or later), the database
must not exceed 256 KB.
Note: Use the cfgsize command to determine the size of the zoning database.

ISL maximums
You can use all ports on all B-series Fibre Channel switches for ISLs, with a maximum of one half of
the total ISL port count configured to the same destination switch.
NOTE:
Some switches require licensing for additional ISL ports.
B-series Encryption Switch fabric rules
This section describes the fabric rules for the B-series Encryption Switches (HP StorageWorks Encryption
SAN Switch and HP StorageWorks Encryption FC Blade) and other factors you should consider when
building fabrics. These switches have a built-in encryption engine and contain 8 Gb/s Fibre Channel
ports (32 for the encryption switch, 16 for the encryption blade) and two GbE ports.
Table 29 describes the rules for creating fabrics with B-series Encryption Switches. For more information
about the security uses of these switches, see “B-series Encryption Switch and Encryption FC Blade
security” on page 410. HP strongly recommends that you read the Brocade Fabric OS Encryption
Administrator's Guide at http://h18006.www1.hp.com/storage/saninfrastructure/switches/
encrypt_sanswitch/index.html?jumpid=reg_R1002_USEN before configuring a fabric using the
encryption switch or encryption blade.
