Hi Kirk,  Yes you are correct.  However, if you want to move across disk types, you can do so with Virtual LUN Technology (VLUN).  Mike
Just finally getting around to setting up optimizer on our dmx4-24 with code 5722. This is different from prior symms in that it has both 10k rpm drives and  15k rpm drives. I don't want to swap between the 2 speeds. I know I can create lists to segragate those disks in the optimzer but I found this to be a pain. I've not seen it documented but it appears the optimizer won't actually suggest a swap across differing rpms - I say that because in attempt to create the lists I get errors if I accidently put a 10k drive in the 15k list (and visa versa). Am I right about that?
