10.6 A STORAGE ARCHITECTURE WITH MULTISWITCH TRUNKING<br />
If the switches to be used for IP storage networking support cross-stack Etherchannel trunking, then each<br />
storage controller needs only one physical connection to each switch; the two ports connected to each<br />
storage controller are then combined into one multimode LACP VIF with IP load balancing enabled. Multiple<br />
IP addresses can be assigned to the storage controller by using IP address aliases on the VIF.<br />
ADVANTAGES<br />
Provides multiple active connections to each storage controller.<br />
<br />
<br />
Easily scales to more connections by adding NICs <strong>and</strong> aliases.<br />
<strong>Storage</strong> controller connection load balancing is automatically managed by the Etherchannel IP load<br />
balancing policy.<br />
DISADVANTAGE<br />
• Not all switch vendors or switch models support cross-switch Etherchannel trunks.<br />
