Combining FCP lif read latency 1.68ms + LUN read latency 1.78ms, would it be right to say complete FCP latency "inside" the controller is 3.46ms? What I'm trying to get is total time spent when FCP read request arrive at controller and leaves FCP port to user.
EDIT: Does LUN or FCP latency include compression, dedup etc?
First testing is OK, but I don't understand how one round trip (which I understand is host requesting two read operations to get two 64k chunks), can add 100ms to the lun latency. And to read 256 (4*64k) adds 2 * 100ms. Must be testing thing or something, those latencies are grazy..
