Managing Sheer DNA Units

The clustered N+m High Availability mechanism within the Sheer DNA Fabric is designed to handle the failure of a Sheer DNA Unit. Sheer DNA Unit availability is established in the Gateway, running a Protection Manager process, which continuously monitors all the Sheer DNA Units in the network. Once the Protection Manager detects a Sheer DNA Unit that is malfunctioning, it automatically signals one of the m servers in its cluster to load the configuration of the faulty unit (from the system Registry), taking over all its managed Network Elements. The switchover to the redundant standby Sheer DNA Unit does not result in any loss of information in the system, as all of the information is auto-discovered from the network, and no persistent storage synchronization is required. When a Sheer DNA Unit is configured it can be designated as being an active or standby unit.

Note: The Sheer DNA system is usually configured with Sheer’s High Availability mechanism enabled.

For more information about high availability, standby units, and defining a redundant unit, refer to the Cisco Active Network Abstraction High Availability User’s Guide.

5.2Adding New Sheer DNA Units

Sheer DNA Manage enables the user to add a Sheer DNA Unit to the Sheer DNA Fabric. Sheer DNA Manage automatically registers the Sheer DNA Unit in the registry and creates a transport uplink between the Sheer DNA Unit and the Sheer DNA Gateway. The Sheer DNA Units are linked to the Sheer DNA Gateway in a star topology.

In addition, the administrator can enable or disable high availability for a Sheer DNA Unit. These settings enable the administrator to define to which protection group a Sheer DNA Unit is assigned and whether it is enabled for high availability.(For more information on high availability, refer to the Cisco Active Network Abstraction High Availability User’s Guide.)

Note: By default all Sheer DNA Units in the Sheer DNA Fabric belong to one big cluster, namely, the default-pgprotection group.
