Use the SAS drives as l2arc for a pool on sata disks. If your l2arc is the full size of your pool, you won't see reads from the pool (once the cache is primed).
If you're purchasing all the gear from new, consider whether SSD in this mode would be better than 15k sas. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
