I've set up an iScsi volume on OpenSolaris (snv_134) with these commands: sh-4.0# zfs create rpool/iscsi sh-4.0# zfs set shareiscsi=on rpool/iscsi sh-4.0# zfs create -s -V 10g rpool/iscsi/test The underlying zpool is a mirror of two SATA drives. I'm connecting from a Mac client with global SAN initiator software, connected via Gigabit LAN. It connects fine, and I've initialiased a mac format volume on that iScsi volume. Performance, however, is terribly slow, about 10 times slower than an SMB share on the same pool. I expected it would be very similar, if not faster than SMB. Here's my test results copying 3GB data: iScsi: 44m01s 1.185MB/s SMB share: 4m27 11.73MB/s Reading (the same 3GB) is also worse than SMB, but only by a factor of about 3: iScsi: 4m36 11.34MB/s SMB share: 1m45 29.81MB/s Is there something obvious I've missed here? -- Hi Matt, here is a decent post on how to setup the COMSTAR and disable the old iscsitgt service. http://toic.org/2009/11/08/opensolaris-server-with-comstar-and-zfs/ Have a great day!
