Hi, we have a F200 filled with 48 NL drives that are working pretty hard. IOPS still seem within an acceptable range, but the Services Time seem high to me, sometime going over 100ms. Now what I am wondering is how can I define a "service time" in the 3PAR. Are they the same as the response time of a single HDD? In that case, a service time over a 100ms would mean something very problematic. But in our scenario, beside few exeptions, most of our systems seem to perform ok, assuming they are running on NL drives.
So I am trying to define exacly what they mean by "service time"
Any thoughts welcome
