Thunder Devices Cluster and Device¶
The Thunder device connecting to the A10 HarmonyTM Controller may be Single, part of a HA pair or part of a VCS cluster. On connecting, a Device Cluster is created within the Provider account in the HarmonyTM Controller. When the next device of the cluster joins, it automatically joins the device cluster.
Partitions and Logical Clusters¶
Thunder devices typically have multiple partitions. The first one is management partition and is used for device administration. Other partitions can only be used for running application services. When Thunder devices are in HA or VCS, the partition structure of the devices is exactly same. Group of same partitions from all the devices make a logical cluster that hosts application services for the servers. When Thunder devices connects to the HarmonyTM Controller for the first time, a tenant account is created under the provider for each logical cluster and the logical cluster is placed under this tenant. However, there is provision to add more than one logical cluster or Lightning ADC cluster in a tenant account.
Users from the devices are synchronized from devices to the A10 HarmonyTM Controller. Users on shared partition are provider administrator and continue to have access to device management. Users on the individual partition are tenant administrator for the tenant created for that partition. Any user created on the device after the first connection of device to A10 HarmonyTM Controller are also synchronized with A10 HarmonyTM Controller.
