I am a little confused by some of the content in this Redbook and would like clarification. The Redbook states in section 2.4(page 18); "A rank enters a saturation state if it is saturated for five consecutive one-minute samples". However, in the documentation included with CKD Test 2(page 48), the results clearly show that the throttling begins immediately. Can someone please clarify when Rank I/O Throttling actually begins.
