+In order to prevent unexpected volume crash, you can use the following formula to calculate an appropriate value for this setting:

+'Guaranteed Engine CPU = The estimated max Longhorn volume/replica count on a node * 0.1'.
-By default 0.25.'
+The result of above calculation doesn't mean that's the maximum CPU resources the Longhorn workloads require. To fully exploit the Longhorn volume I/O performance, you can allocate/guarantee more CPU resources via this setting.
+If it's hard to estimate the volume/replica count now, you can leave it with the default value, or allocate 1/8 of total CPU of a node. Then you can tune it when there is no running workload using Longhorn volumes.
