We do almost the same. We pull every week the data from dfm in a sql 2005 database and use the report module of ms sql 2005 to make reports. We need an overview longer than 1 year and we need also to track data movements. This last thing (I move a qtree/volume to another filer) is very difficult to do in dfm. This is a new resource for dfm. We have create in dfm a lot of custom tags that we use to build our reports.

RE: Interesting FAS250 note on Tape connectivity
by Learmonth, Peter 11 Oct '06

11 Oct '06

Hi Guys Couple notes on ROHS v. non-ROHS FAS250/270. Yes, all the FC connections are now SFP sockets. ROHS FAS270 has two SFP ports: one for tape or FC SAN (with SFP installed) and one for disk expansion shelves (no SFP installed). ROHS FAS250 has one SFP port for tape (with SFP installed). You can tell in sysconfig -a or -v which one you have by the manufacturing part number (a.k.a. 3x5 number) FAS250 non-ROHS 110-00016 FAS250 ROHS 110-00052 FAS270 non-ROHS 110-00046 FAS270 ROHS 110-00051 Supposedly, all units shipped after a certain date (08 May 2006) are supposed to be ROHS versions. I haven't found that to be entirely reliable. As for what you get via RMA, "It depends (tm)". Basically, if you have ROHS, you should get ROHS. If it ships to a ROHS country and it's after the ROHS compliance date, you get ROHS even if you originally had non-ROHS. If it ships to a non-ROHS country and you have non-ROHS, you get a non-ROHS replacement, at least until they run out. In general, the only problems with getting a ROHS replacement for a non-ROHS is tape connection on FA250 and shelf connection on FAS270. For the non-ROHS FAS250 and tape, if you have an optical tape interface, you're probably using some kind of converter, like Tim Naple was talking about. Now you don't need it. If you have a copper connection to tape, you need a different cable with SFP instead of HSSDDC2. For FAS270 shelves, you'll need X6530 SFP-SFP shelf cables from each head (i.e. 2 in a cluster) to the first shelf. I don't know if the RMA procedure checks for that, but you can certainly tell from sysconfig (it lists both the head part numbers and the modules in the shelves). Personally, I think the change to SFP is a good thing since overall it greatly simplifies cabling. Share and enjoy!

FAS960: backup speed vs simultaneous dumps...?
by Glascock, Donald 11 Oct '06

11 Oct '06

Hi, Toaster folks -- We're a small research group on our third Filer, which is a single FAS960 with five shelves on two cross-connected 2-Gb loops. We trigger flexVolume-level dumps of our one aggregate directly to 2-Gb-fibre-connected LTO-3 drives. When we dump two volumes simultaneously to two tape drives, the time taken to dump each volume increases by a third to a half again, compared to dumping each volume independently. For example, a stand-alone dump may take two hours, but if another dump of another volume to another drive is run simultaneously, then that two-hour dump becomes a three-hour dump. Adding a third simultaneous dump to a third drive causes an even greater increase in dump times. For diagnostic purposes, I've launched a conventional dump of one volume triggered via NDMP our backup software, waited for the dump to reach Phase-IV (the writing-data phase), and launched from the FAS960's console a dump of another volume to the FAS960's null device. Soon after this second dump starts, the write speed on the tape drive associated with the first dump falls off by quite a bit. This write speed picks up instantly when I kill the second dump. Since the second dump was only in Phase-I (inspecting files, but not writing them), and since this second dump was to the local null device anyway, I'm led to think that the performance issues lie somewhere within the Filer's head and Disk I/O subsystem. With one-at-a-time backups of our volumes, our full backup window is about eight hours (for about two terabytes). We were planning to buy two more shelves in early 2007. Should I expect a FAS960 to handle two or three simultaneous full dumps without a significant loss in dump speed? Are you getting nearly-linear performance out of your simultaneous dumps? Thanks for your time & have a great day! Don Glascock -- Donald S.

Well, our secondary suppliers (Majenta Solutions, for the record, and they are totally blameless in all this as far as I can see) did finally manage to get us the following deal 4 hour onsite cover for the base filer Next Busness Day parts delivery for the shelf and disks (it proved impossible to distinguish the shelf from the disks) for about the mean of the all-4hr and all-NBD quotes. So we went for that. Or so we thought... We have had two disk failures since then [*] and on each occasion NetApp shipped a replacement disc to the 4-hour schedule. So they must think that is what we paid for. I suppose it ought to be flattering that NetApp think we require a replacement disk that fast, but actually it's a pain in the posterior, as we aren't set up to accept deliveries 7x24. I suppose next year we'll say To Hell With It, and go for NBD for everything. [*] an unusually high rate in a 14-disc system, on past experience: one of them was just after a reboot upgrading ONTAP, the other a few hours after a scheduled outage of our Uninterruptible Power Supply ... no, don't ask, you don't want to know :-( -- Chris Thompson Email: cet1(a)cam.ac.uk

Has it been anyone else's experience that IBM is beating the pants off of other resellers? I'm talking by 50%? I'd like to hear from you if you find this the case as well.

RE: Removing a disk from an aggregate
by Fox, Adam 10 Oct '06

This is generally not possible. The only disks that can be removed from an aggregate is the dparity disk by changing the RAID type from RAID-DP to RAID-4. And you can only do this if your current RG is not over the max size for RAID-4. Sorry. -- Adam Fox NGS Tools Developer adamfox(a)netapp.com -----Original Message----- From: Alan Biren [mailto:ABiren@asisystem.com] Sent: Tuesday, October 10, 2006 12:37 PM To: toasters(a)mathworks.com Subject: Removing a disk from an aggregate Does anyone know of a way to permanently remove a disk from one a RAID Group in an Aggregate. One of my Administrators create an aggregate with raidsize of 14 disks and used all available disks to fill the raid group. There are now no spares in the system. The current aggregate already has a production volume on it so destroying the aggregate is really not an option.
