Symptoms
Most common symptom is SAN freezing. You will definitely notice if that happens 🙂
Rare symptoms are:
- Storage performance degradation (XXXXms) messages in StarWind and Windows Application logs.
- Storage becomes unreachable due to freezes and performance degradation.
- Synchronization might get lopped (more information about that can be found here: http://knowledgebase.starwindsoftware.com/explanation/synchronization-process-is-looped/
Solution
Enable Jumbo Frames (MTU) of switch and check that it is enabled on all network interfaces that are presented to StarWind.
