Supported Configurations
Operation of multiple switches in a fabric topology is subject to the following
topology limits. Consider the impact of these limits when planning the fabric.

Fabric Elements – Each fabric element is defined by a unique domain ID that
ranges between 1 and 31; therefore, the theoretical limit of interconnected
switches in a single fabric is 31. The supported limit of interconnected
switches in a single fabric is 24. Because this number is subject to change,
contact your HP authorized service representative for the current number of
interconnected switches supported in a single fabric.
Inhomogeneous fabric – To determine if interoperability is supported for a
product, or if restrictions apply, refer to the product publications, or contact
your HP authorized service representative.
Number of Interswitch Links (ISLs) – The maximum supported number of
ISLs for edge switches is all available switch ports. For redundancy, at least
two ISLs should connect any two switch-class fabric elements. Because this
number is subject to change, contact your HP authorized service
representative for the current number of ISLs supported per switch.
Hop Count – The Fibre Channel theoretical limit of ISL connections
traversed (hop count) in a single path through a fabric is 7. The maximum
supported hop count in a single path through a fabric is 3. Because this
number is subject to change, contact your HP authorized service
representative for the current hop count supported by a single fabric path.
The hop count is equal to the number of ISL connections traversed in a single
.
