High availability
1
Port groups for configuring operation modes are illustrated in
. If you configure a port group
in Performance mode, the first two ports in a group are enabled for Performance mode. The third
port is disabled as it can only be configured in density mode only. If you configure the port group in
Density mode, all three ports are enabled for density mode. To identify the port group, use the
format rbridge-id/slot-id/port group-id. For example, 1/3/9 denotes RBridge 1, slot 3, and
port-group-id 9.

commands, refer to

High availability
High availability is currently limited to management module configuration synchronization. Failover
to the standby module will occur in case of active module failure, but the standby module will go
through a cold recovery in which all system components are reset. This will disrupt traffic on the
chassis. The reset could take up to eight minutes depending on chassis configuration and traffic
load.
The Brocade VDX 8770-4 provides the following features to enhance and ensure serviceability:
•
Modular design with hot-swappable components.
•
Flash memory that stores two firmware images per control processor.
•
USB port on management module for most tasks that formerly required an FTP/SCP server,
including software and firmware upgrades.
•
Nonvolatile random-access memory (NVRAM), containing the OEM serial number, Brocade
serial number, revision information, and part number information.
•
Background health-check daemon.
•
Memory scrubber, self test, and bus ping to determine if a bus is not functioning.
•
RASlog messages.
•
SMI-S compliant.
