Cluster Tab

Multiple standalone Deep Discovery Analyzer appliances can be deployed and configured to form a cluster that provides fault tolerance, improved performance, or a combination thereof.

Depending on your requirements and the number of Deep Discovery Analyzer appliances available, you may deploy the following cluster configurations:

Cluster Configurations

Cluster Configuration	Description
High availability cluster	In a high availability cluster, one appliance acts as the active primary appliance, and one acts as the passive primary appliance. The passive primary appliance automatically takes over as the new active primary appliance if the active primary appliance encounters an error and is unable to recover.
Load-balancing cluster	In a load-balancing cluster, one appliance acts as the active primary appliance, and any additional appliances act as secondary appliances. The secondary appliances process submissions allocated by the active primary appliance for performance improvement.
High availability cluster with load balancing	In a high availability cluster with load balancing, one appliance acts as the active primary appliance, one acts as the passive primary appliance, and any additional appliances act as secondary appliances. The passive primary appliance takes over as the active primary appliance if the active primary appliance encounters an error and is unable to recover. The secondary appliances process submissions allocated by the active primary appliance for performance improvement.

For details, see the Deep Discovery Analyzer Installation and Deployment Guide.

The following table lists the available configuration modes and associated appliance behavior.

Cluster Configuration Modes

Configuration Mode	Description
Primary (Active)	Management console is fully accessible Retains all configuration settings
Primary (Passive)	Management console is unavailable Automatically configured based on the settings of the active primary appliance On standby Takes over as the active primary appliance if the active primary appliance encounters an error and is unable to recover Does not process submissions
Secondary	Automatically configured based on the settings of the active primary appliance Identifies the active primary appliance using its IP address or virtual IP address Processes submissions allocated by the active primary appliance for performance improvement Management console only shows screens with configurable settings: Virtual Analyzer → Sandbox Management → Network Connection Virtual Analyzer → Sandbox Management → Sandbox for macOS Administration → Updates → Hotfixes / Patches Administration → Updates → Firmware Administration → Integrated Products/Services → SAML Authentication Administration → System Settings → Network Administration → System Settings → HTTPS Certificate Administration → System Settings → Cluster Administration → Accounts / Contacts → Accounts Administration → System Logs Administration → System Maintenance → Network Services Diagnostics Administration → System Maintenance → Power Off / Restart Administration → System Maintenance → Debug Administration → License

Note

In environments that use a load-balancing cluster or a High Availability cluster with load balancing, Deep Discovery Analyzer automatically slows down Virtual Analyzer throughput on the active primary appliance to prevent exhaustion of system resources
