I use ZFS to present iSCSI to Microsoft Data Protection Manager to handle Exchange backups as well. Not sure if its just the workload DPM presents, but I had to disable the ZIL to increase performance as well. We do not have SSD's on our X4540s yet as we don't want to sacrifice any drive bays. Any way to handle the zil and synching on a per-filesystem basis would be great for our workload. -- Brent Jones [email protected] _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
