low throughput with NetApp filer.
by Harbhajan Julka 26 May '04

26 May '04

Hi everyone, I have encountered a problem with a NetApp filer F720. I get a very very low throughput from the filer when i try a backup to a StorageTek tape connected to it, the throughput being 6 MB/min. And, i have known from some other NetApp users that the filer can give a max of 45 MB/min. If i connect the same tape to some other windows m/c and do the backup, the throughput rises to 116 MB/min and keeps increasing thereon. Now, i tried both local and remote backups to the tape. I did a backup of data from the disk on the filer to a tape locally connected to it. Also, i tried a remote backup of data from a remote m/c to the tape. The throughput in the 1st case was 13 MB/min while for the second, it was 6 MB/min. I have considered any network congestion that might cause a low throughput, but a remote backup to a tape on a windows m/c was pretty high (116 MB/min), which only leads to that probably the filer's is reducing the throughput. I need help in figuring out where the problem lies. To my conjecture, i believe it is the filer thats somehow spending a lot of time reading and writing from/to the tape. Any suggestions are welcome. I look forward to a lot of replies. Thanks a lot, Sonia. --------------------------------- Do you Yahoo!? Win a $20,000 Career Makeover at Yahoo! HotJobs

RE: NDMP backup speeds
by Blake, Delroy 25 May '04

25 May '04

You should see at least native rates on you backups. I would do s sysstat -s -c 100 1 and see what CPU and network speeds are. For AIT-2 I get 6-12 MB/s For LTO it was Closer to 15 MB/s This was three way backup with Sun 420R or Windows 2002 (DL580/DL580 G2) How many filers are backing up at once? You may need multiple GE networks to take advantage of the speed. Also Contention on the volumes that house qtree could also slow you down. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Geoff Hardin Sent: Tuesday, May 18, 2004 5:53 PM To: toasters Subject: NDMP backup speeds Toasters, What is the general consensus for NDMP backup speeds? I have four older F760Cs that are getting about 5-6 MB/s to local tape drives. The problem is that I also have another nine filers (1 F630, 1 F720, 1 F740, 6 F760C) that are backing up via 3-way NDMP and we are lucky to see 4-5 MB/s; most are in the 1-2 MB/s range. And don't even get me started on the Solaris/SunOS/Linux/HP-UX/DEC clients that backup through the drives attached to the filers (0.1 - 2 MB/s). We were looking at upgrading the tape drives and such, but we have done a few test dumps from filer to filer, filer to LTO-2, and filer to LTO-2 attached to a Sun, and the numbers didn't improve much (definitely not enough to justify buying a new tape library / tape technology). Just a little background: We are using DLT7000 tape drives, which should have a maximum through put of about 10 MB/s (2:1 compression), contained in a Quantum P3000 library. We have all our filers on two separate networks; one for general data sharing and a private one for our backups. The private network is all GbE (fibre) using the Alteon GbE cards (Gigabit Ethernet Controller II). We are doing qtree dumps, and while some of the filers have only four qtrees per volume, others have over 40. Each qtree is generally capped at 200 GB max, and for those filers that have lots of qtrees, we still try to limit each saveset to around 200 GB. So, I guess what I'm really asking is 1) "What kind of speeds are you seeing?" and 2) "Am I doing something wrong?" Many thanks, Geoff Hardin geoff.hardin(a)dalsemi.com Difficulty is the excuse history never accepts.
