I have Storage-SAN of HDS(AMS500), and I want to do striping on luns from the storage. I don''t want any raid-5(because I have one on the disks in the HDS storage). I only want to do strip on 2 luns(25GB each) that cames from different controllers and deffrent fiber channel port(dual HBA). I test the preformance by writing 512MB in to the zfs, with 2 luns striped(each lun from diffrent controller and connected from diffrent port of the dual HBA). also I test the by writing 512MB into zfs, with only one lun, BUT the preformance was the same. I thougth the the preformace should be doubled!??? another question , can I do concatination in zfs? This message posted from opensolaris.org
