Hello, Dmitry. You wrote 19 марта 2013 г., 21:45:57: DM> I'm currently in process of making new backup server, based on LSI 9260 DM> controller.

You don't need JBOD mode, you need many separate disks, added to ZFS vdev. It allows ZFS to plan parallel requests & distribute vital metainformattion properly. -- // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
