Large-scale server virtualization use case

The following figure shows an example of 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
