Configuration for the Brocade VDX 6740 switches
The Brocade VDX 6740 switches can be configured in VCS™ mode, which is enabled by default.
In VCS mode, the switch is part of an Ethernet fabric involving two or more VCS-enabled switches.
VCS technology embodies the concepts of distributed intelligence and logical chassis. Distributed
intelligence means that all configuration and destination information is automatically distributed to
each member switch in the fabric. Distributed intelligence has three major characteristics:
• The fabric is self-forming. When two VCS-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). Automatic Migration
of Port Profiles (AMPP) supports VM migration to another physical server. If the VM moves, it is
automatically reconnected to all of its original resources.
Logical chassis means that the entire VCS fabric appears and can be managed as a single Layer 2
switch. There are three major characteristics to logical chassis:
• Each physical switch in the fabric can be managed as if it were a blade in a chassis. When a
VCS-enabled switch is connected to the fabric, it inherits the configuration of the fabric and the
new ports become available immediately.
• You can manage the entire fabric from any switch.
• You can manage the edge switches in the fabric as if they were a single switch.
