Ta on the comments.... I'm going to use Jorg's 'star' to simulate some sequential backup workloads, using different blocksizes and see what the system do.
I'll save some output and post for people that might match the same config, now or in the future. To be clear though: (currently) #tar cvfE /dev/rmt/0cbn /tmp/foobar (42 MB/s to tape sustained, 70% util on tape device) #tar cvfE /dev/rmt/0cbn /oracle/datafiles/* ( 24 MB/s to tape sustained, 24-60 MB/s zfs fs bursts) I'll post the star, iostat and other findings later. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
