There are Works to make NDMP more efficient in highly fregmanted file Systems with a lot of small files. I am not a development engineer so I don't know much and I do not think that there is any committed work. However ZFS engineers on the forum may comment more Mertol

Now...yes. We implemented this pool years ago. I believe, then, the server would crash if you had a zfs drive fail. We decided to let the netapp handle the disk redundency. Its worked out well. I've looked at those really nice Sun products adoringly. And a 7000 series appliance would also be a nice addition to our central NFS service. Not to mention more cost effective than expanding our Network Appliance (We have researchers who are quite hungry for storage and NFS is always our first choice). We now have quite an investment in the current implementation. Its difficult to move away from. The netapp is quite a reliable product. We are quite happy with zfs and our implementation. We just need to address our backup performance and improve it just a little bit! We were almost lynched this spring because we encountered some pretty severe zfs bugs. We are still running the IDR named "A wad of ZFS bug fixes for Solaris 10 Update 6". It took over a month to resolve the issues. I work at a University and Final Exams and year end occur at the same time. I don't recommend having email problems during this time! People are intolerant to email problems. I live in hope that a Netapp OS update, or a solaris patch, or a zfs patch, or a iscsi patch , or something will come along that improves our performance just a bit so our backup people get off my back! -- Ed _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
