Hi Kory, It depends on the capabilities of your array in our experience...and also the zpool type. If you're going to do RAID-Z in a write intensive environment you're going to have a lot more I/Os with three LUNs then a single large LUN. Your controller may go nutty.
Also, (Richard can address this better than I) you may want to disable the ZIL or have your array ignore the write cache flushes that ZFS issues. Best Regards, Jason On 12/12/06, Kory Wheatley <[EMAIL PROTECTED]> wrote:
This question is concerning ZFS. We have a Sun Fire V890 attached to a EMC disk array. Here's are plan to incorporate ZFS: On our EMC storage array we will create 3 LUNS. Now how would ZFS be used for the best performance? What I'm trying to ask is if you have 3 LUNS and you want to create a ZFS storage pool, would it be better to have a storage pool per LUN or combine the 3 LUNS as one big disks under ZFS and create 1 huge ZFS storage pool. Example: LUN1 200gb ZFS Storage Pool "pooldata1" LUN2 200gb ZFS Storage Pool "pooldata2" LUN3 200gb ZFS Storage Pool "pooldata3" or LUN 600gb ZFS Storage Pool "alldata" This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
