There are three ways to interconnect QLogic 9000 Series switches. The method 
you choose depends on your port count and bandwidth needs:



SFP port-to-SFP port



X2 port-to-X2 port



ICC port-to-ICC port

An SFP-port connection provides up to 1700 MB of full duplex bandwidth for a 
FC8G16 I/O blade, while sacrificing an SFP port that would otherwise be available 
for devices.

An X2-port connection is established using an X2-X2 stacking cable. A 10-Gbps 
I/O blade is required in each switch. A 10-Gbps connection provides 2550 MB of 
full duplex bandwidth while preserving the SFP ports for devices. Refer to 

 for more information.

ICC port connections require the HyperStacking license key on both switches and 
four HyperStacking cables. Each HyperStacking cable consists of eight 10-Gbps 
links connecting a CPU blade on one switch to a CPU blade on the second switch. 
This provides a total of 81.6 GB of full duplex bandwidth while preserving the 
I/O blade ports for devices. Refer to 

 for more 

information.

                                                                                           

If you connect two QLogic 9000 Series switches that have the same domain 
ID, the switches will isolate–there is no automatic domain ID conflict 
resolution. You must explicitly change the domain ID on one of the switches.
