I Have a hardware-raid running. A = mirror thats the only storage in my zfs pool. Im going to add another mirror to the machine and my question is, what is the best = option performace-wise? Is it to add the other mirror to the same pool or create another = separate pool for that mirror?=20 Btw. Today my disk are quite saturated r/w wise. -- Peter Ankerst=E5l peter@pean.org http://www.pean.org/
