Hi, when creating LUNS greater than 200GB we generally create them as meta volumes, the members are generally 200GB. 

If I was to create a 2TB Meta Volume would it make a difference to performance if the members were 100GB compared to say 200GB? I'm thiking that would require a greater spread of TDATS across more disks

I'm seeing consistent high latency on a SQL mirror backed by a raid6 pool lun.  FAST isn't promoting the LUN which is a total of 4TB, I'm told that only hot spots are moved not the entire LUN, but nothing moves and performance isn't great, which brings me to my second question - if I migrate the LUN to FC on a RAID10 pool would that be my safest bet to preserve data and improve performance?

Thanks All
