Hi Bruno,

When a Failover switch is triggered, it will go through 4 steps:

1. Stop the DataMiner software
2. Release the VIP IP (or the first steps are covered by the server going offline abruptly)
3. The other DMA can take over the VIP
4. The DMA can perform a DataMiner start.

To know where your system is losing most of its time, you will need to go through logging. It's easiest to look for the reassignment of the VIPs, which can be checked in the SLFailover logging on both main and Failover. This will already tell you when these steps occurred and how long they took. If you lose most of the time after reassigning the VIPs, it is best to look into the SLDataMiner logging file. There you will find how long it took to offload data (if any) to the DB, evaluate all the protocols in your system, start all the elements and services. An easy way to speed up your startup time is by removing unused protocol versions in your system.

Note: Logging can be found on the server itself in the folder C:\Skyline DataMiner\logging.
