As shown in the network diagram, a VLT domain is established between ToRs that belong to the same system and also between the aggregation switches. This is essential to ensure that an HA networking topology and maximum bandwidth is available during fault scenarios. Ensure that the interfaces participating in the VLT domains have adequate bandwidth to continue to serve required storage performance at times of switch or cable failure.
Configuration of the VLT domains is beyond the scope of this implementation guide.
