NOTE
Optimizer policies are also implemented globally across all cluster nodes. For example, if there were a single policy to
restrict all traffic to 1Mbps, this would be applied across all cluster nodes. So, the sum of all traffic through all cluster
nodes would not exceed 1Mbps.
Shared Monitoring Information
All appliances in the cluster can be monitored. Most monitoring information is shared across the cluster. Some reports
don’t make sense to share (e.g. Interface reports); however, most reports are synchronized, including:
Realtime
Network
AQS
Applications and URLs
Hosts
Conversations
Subnets
NOTE
When monitoring information is shared across the cluster, the timestamp on this information is not shared across the
cluster. New timestamps are added to the data when it enters the other appliances in the cluster. If there is a delay
in sharing this information, which could be due to the appliances in the cluster being separated physically by a
great distance or by not providing enough bandwidth between the clustered appliances, the reports may not
appear similar on the different appliances in the cluster.
When a cluster node fails
In the event that a node in the cluster fails, is rebooted, or powered off, bypass mode is enacted and traffic passes
though unaffected. When the appliance comes back online, the node is updated with the latest configuration settings
from the Cluster Master and normal operations resume. Monitoring and reporting information during the downtime is
not synchronized after the fact.
In the event that the Cluster Master fails, is rebooted, or powered off, a new Cluster Master is automatically elected. The
offline node (previously the Cluster Master) is treated as a regular offline node. When it comes back online, it does not
necessarily become the Cluster Master.
