Hi,
i have several equallogic groups, mostly consisting of PS6500's. and in every setup the volume move happens at aproximately 33.5MB/s
so about 1/3 of a single connection. The volume move actually does only use a single connection as well.(but that is not an issue).
I don't use automatic tiering, so i do this manually. But transferring a volume to a differente pool does take a considerable amount of time. During nighttime there are almost no iops in my setup, so it would be a great feature if volume movement could be speeded up a little :)
