A little setback.... We found out that we also have the issue with the Dell H800 controllers, not just the LSI 9200-16e. With the Dell it's initially faster as we benefit from the cache, but after a little while it goes sour- from 350MB/sec down to less than 40MB/sec. We've also tried with a LSI 9200-8e with the same results.
So to recap... No matter what HBA we use, copying through the network to/from the external drives is painfully slow when access is done through either NFS or iSCSI. HOWEVER, it is plenty fast when we do a scp where the data is written to the external drives (or internal ones for that matter) when they are seen by the Nexenta box as local drives- ie when neither NFS or iSCSI are involved. What now? :) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
