With Brocade VCS Fabric technology, all relevant information is automatically distributed to each member switch to provide unified fabric functionality, as illustrated in the following figure.
A Brocade VCS Fabric is designed to be managed as a single "logical chassis," so that each new switch inherits the configuration of the fabric, and the new ports become available immediately. The fabric then appears to the rest of the network as a single switch. This significantly reduces complexity for the management layer, which in turn improves reliability and reduces troubleshooting.
In addition, VCS Fabrics provide a NETCONF application programming interfaces (API), as well as extensions to OpenStack Quantum to orchestrate both physical and logical networking resources as part of virtual machine deployment to support multi-tiered application topologies.
Distributed intelligence has the following characteristics:
- The fabric is self-forming. When two Brocade VCS Fabric mode-enabled switches are connected, the fabric is automatically created and the switches discover the common fabric configuration.
- The fabric is masterless. No single switch stores configuration information or controls fabric operations. Any switch can fail or be removed without causing disruptive fabric downtime or delayed traffic.
- The fabric is aware of all members, devices, and virtual machines (VMs). If the VM moves from one Brocade VCS Fabric port to another Brocade VCS Fabric port in the same fabric, the port-profile is automatically moved to the new port, leveraging Brocade’s Automatic Migration of Port Profiles (AMPP) feature.
