Hi guys
I wanted to ask how i could setup a iSCSI device to be shared by 2 computers

I tried and setup iSCSI on both computers and
NTFS is not a clustered file system and thus can't handle multiple clients
accessing the data. You could use MelioFS if you're Windows based, which
handles metadata updates and locking between the accessing nodes to be able
to share a NTFS disk between them - even over iSCSI.
MelioFS:
And.. if you're using iSCSI towards ZFS and want to have shared access, take
a look at GlusterFS which you use in front of multiple ZFS nodes as
accessing point.

Yes, and I apologize for basic nature of these questions. Like I said, I'm
pretty wet behind the ears with zfs. The MB/sec metric comes from dd, not zpool
iostat. zpool iostat usually gives me units of k. I think I'll try with smaller
