Operational modes
Network OS supports three operational modes for Brocade VDX switches.
The three operational modes are:
• Logical chassis cluster mode — One of two types of "VCS" modes for a switch. This mode requires
Network OS 4.0.0 or later. In this mode, both the data and configuration paths are distributed. The
entire cluster is configured from the principal node. Refer to
55 for more information.
• Fabric cluster mode — The second of two types of "VCS" modes for a switch. In this mode, the data
path for nodes is distributed, but the configuration path is not distributed. Each node keeps its
configuration database independently. Refer to
on page 57 for more
information.
• Standalone mode — Only the Brocade VDX 6710-54, 6720, and 6730 support this mode. Refer to
on page 58 for more information.
When a new switch boots up, the switch enters either standalone mode or fabric cluster mode,
depending on the switch model.
ATTENTION
The generic term VCS mode in this manual applies to both fabric cluster mode and logical chassis
cluster mode unless otherwise stated.
Logical chassis cluster mode
Logical chassis cluster mode is defined as a fabric in which both the data and configuration paths are
distributed. The entire cluster must be globally configured from the principal node. Logical chassis
cluster mode requires Network OS 4.0.0 or later.
Logical chassis cluster mode support for platforms
The following platforms support logical chassis cluster mode and is used in any combination:
• Brocade VDX 6710
• Brocade VDX 6720
• Brocade VDX 6730
• Brocade VDX 6740
• Brocade VDX 6740T
• Brocade 6740T-1G
• Brocade VDX 8770-4
• Brocade VDX 8770-8
