Hi, When you have a lot of random read/writes, raidz/raidz2 can be fairly slow. http://blogs.sun.com/roch/entry/when_to_and_not_to
The recommendation is to break the disks into smaller raidz/z2 stripes, thereby improving IO. >From the ZFS Best Practices Guide: http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#RAID-Z_Configuration_Requirements_and_Recommendations "The recommended number of disks per group is between 3 and 9. If you have more disks, use multiple groups." -Scott -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
