Primary Failover Timing Measurements
The table below demonstrates how much time is needed once the primary node fails, until the high available instance (which has been created there), becomes active and healthy again on failover node.
| Recovery Status on Failover node | Maximum Elapsed time |
|---|---|
| Controller active on Failover node | 1 minutes, 22 seconds |
| Controller is reachable | 1 minutes, 24 seconds |
| Database METADATA synchronization | 3 minutes, 35 seconds |
| Sunlight API becomes ready | 6 minutes, 13 seconds |
| High available VM is active and healthy on Failover node. (the reported time might vary according to the number and the size of the HA VMs to be migrated |
8 minutes, 12 seconds |
