主题: Question: About the number of identify

We know that identify frame can be sent one or three to the other side after speed negotiation completed.
What I want to know is what is the consideration? Just ensure the other side can receive identify?
Is there any chance that a SAS PHY will miss the first identify frame?
Now I met a issue. When the host send just one identify frame, the HDD will occur receiving identify expired with little probability. This issue will be fixed when the host send three identify frame.
