What is a BIG-IP Device Service Clustering (DSC) group and how do I start managing it from BIG-IQ?
Device Service Clustering
, or DSC, is a BIG-IP TMOS feature that lets you organize BIG-IP devices in groups to share configurations. These groups are called device service clusters
(also DSC). With BIG-IQ, you can manage devices configured in a DSC, and their shared objects, from one centralized location. Before you can manage BIG-IP systems configured in a DSC, you must:
- Add the DSC device members to the BIG-IP Devices inventory.
- Add the DSC group to the BIG-IP Clusters inventory.
- Ensure that each DSC group includes at least one sync-failover configuration.
When a DSC group is in the BIG-IP Cluster inventory, you can view its properties and the devices within those groups, and synchronize their configurations, all without having to log in to each device individually. This allows for automatic synchronization among devices for any changes on objects defined in the cluster.
For specific information about BIG-IP DSC groups, refer to the
BIG-IP Device Service Clustering: Administration
guide.It is important to note, that although objects are shared among devices in a DSC group, they appear based on the state of each managed BIG-IP device. This can indicate that objects, such as a shared pool, is offline for a specific device that is experiencing network issues. However, the pool will appear as online for other devices in the DSC group.
