Management modules

Two management modules (MMs) provide redundancy and act as the main controller on the Brocade VDX 8770-4 and VDX 8770-8 chassis. The management modules host the distributed Network OS that provides the overall control plane management for the chassis. You can install a redundant management module in slot M1 or M2 in any of the Brocade VDX 8770 chassis. By default, the system considers the module in slot M1 the active management module and the module in slot M2 the redundant, or standby, management module. If the active module becomes unavailable, the standby module automatically takes over management of the system.

Each management module maintains its own copy of the configuration database. The startup configuration is automatically synchronized with the other management module.

Brocade recommends that each management module (primary and secondary partition) should maintain the same firmware version. For more information on maintaining firmware, refer to the “Installing and Maintaining Firmware” section of the Network OS Upgrade Guide.

Each management module has two Ethernet interfaces, Eth0 and Eth2. Eth0 is the management interface and can be configured with an IP address. For more information on configuring the management interface, refer to Connecting to a switch.
