Large-scale server virtualization use case
The following shows a logical two-tier architecture with Brocade VCS fabrics at the edge. Each Brocade
VCS fabric appears as a single virtual switch to the switches outside the fabric, which results in
flattening the network.
FIGURE 6 Collapsed, flat Layer 3 networks enabling virtual machine mobility
Brocade VCS Fabric technology in this use case provides the following advantages:
• Optimizes the multipath network (all paths and Layer 3 gateways are active, no single point of failure,
and STP is not necessary)
• Increases sphere of Virtual Machine (VM) mobility
