Use of Irules in persistence profile and vs

You've asked a very good question.

 

 

There actually isn't any difference in terms of how the rules are evaluated.

 

The difference is really how you want to manage the rule.

 

 

For example, if the rule is really about setting up persistence and a particular virtual simply wants to use that persistence, then putting the rule on the persistence profile might make more sense. This way, if you need to change the rule to include some virtual specific stuff like which pool(s) to use, you can keep that in a separate rule that's only attached to the virtual. Then if you later need to modify either rule, you are not affecting the other. Another case might be that you want to add or remove that persistence on a given virtual, in which case it might make more sense to add or remove the persistence profile instead of the rule.

 

 

So, in summary, there really isn't any difference in how the rule is evaluated and the difference purely allows for your choice of management.

 

 

Hope that helps.
