Support for F760s?
by Patricia Dunkin 21 Jul '06

21 Jul '06

My records indicate that NetApp stops supporting F760s at the end of this month. Does anyone have experience with companies providing third-party support, especially in New Jersey? Thanks. -- Patricia Dunkin Lucent Technologies - Bell Labs Innovations pdunkin(a)lucent.com 600 Mountain Avenue 3C-306C Phone: 908-582-5843 Murray Hill, NJ 07974-0636

FAS3050 and Oracle over NFS - recommendation needed
by Sto Rage© 21 Jul '06

21 Jul '06

Fellow Toasters, We purchased a new FAS3050c with the intent of using it for Oracle over NFS. This will be our first exposure to Oracle over NFS as we are migrating from a SAN environment (EMC Symm 8430), so we need to ensure we get as good a performance we got from our SAN. The filers would also be serving regular CIFS and NFS data. Here's the configuration, please suggest the best way to lay out the aggregates in order to provide optimum performance for Oracle over NFS. Filer Configuration: - FAS3050c with 6 shelves (3 shelves per head). Shelves are with 300GB 10K FC drives. No additional add-on cards, just with 4 built-in Gig-E and FC ports each. - The 3 shelves are all on a single loop now, would this be a problem? There are 2 FC ports free for future shelf expansion. Should we start off with 2 loops now, 1 loop with 2 shelves and 1 with just 1 shelf? - On each head, we have created a VIF using 2 NICs each, exclusive for Oracle NFS traffic with Jumbo frames enabled and hooked to a dedicated Gigabit switch with no routing outside. One NIC is configured for regular CIFS/NFS traffic and will be on our normal LAN. The 4th NIC is un-configured at present. There will be 4 Solaris 10 boxes running Oracle, 2 production and 2 dev, each with 1 NIC dedicated for oracle NFS and jumbo frames enabled. We may add a 2nd NIC to the production hosts and trunk it for Oracle NFS in the future and at that time add the 3rd NIC on the filers to the VIF. Does this network configuration look reasonable. The oracle application will have about 100 to 150 users running ERP, with about 50 to 60 concurrent users. The database size is not large, under 500GB (including dev and production) Now the question on creating the aggregates. We definitely want to get the best performance possible and at the same time don't want to sacrifice too much capacity by creating smaller RAID groups. So this is what I have in mind: On each head, create 2 aggregates with 20 disks each, leaving 2 disks as spare. The aggregates will have a raid size of 20 disks (instead of the default 16), there by maximizing the disks for data (about 4 TB usable per aggregate). This means there is just 1 RAID set per aggregate. Is this OK? What would be the impact when there is a disk failure and rebuilds? Is it better to create smaller raid groups with a raidsize of 10 to minimize rebuild performance? Should we look at creating 1 single aggregate with 40 disks? I know more the spindles the better for an aggregate, how big a difference will a 40 disk aggregate make over a 20 disk one? When does the spindle count max out performace? Hope this is enough information to start a meaningful discussion. Looking forward to all of your valuable inputs. The NetApp white papers don't have these kind of detailed configuration inforamtion. TIA -G

ESTATE ACQUISITION
by Rev Dave Igebe 20 Jul '06

20 Jul '06

Hello Dear, I am Dave Igebe, a West African based legal practitioner from Britain,a spiritual counsellor with MEN OF FAITH INT. and Pro- Director of Rwanda Rehabilitation Project. I have a colleague/client who was the former Director of environmental matters in the defunct Government of assasined President Juvenal Habyarimana of Rwanda. My client was unjustly removed from office by succeeding President Bizimungu for being a Tutsi origin; She was detained and brutalised for her historical origin. You can visit this website: http://news.bbc.co. uk/1/hi/world/africa/1288230.stm http://www2.unog. ch/news2/documents/newsen/sg04003e.htm http://www.un. org/av/photo/unhq/projectrwanda040704.htm for further details. My client ( Ms Mebezu Osimatoye) is presently in Adis Ababa and wants to acquire Estates or landed properties in your country. Considering her very strategic and influential position, She would want the transaction to be as strictly confidential as possible.She further wants her identity to remain undisclosed at least for now, untill the completion of the transaction to avoid traces by the present Government of President Paul Kagame that laid embargo on fund transfer to/from Rwanda more especially when it has to do with Tutsi origins; Hence her desire to have an overseas agent. I am therefore making enquiries on her behalf if you would agree to act as her oversea agent in order to actualize this dream. The deal,in brief, is that the funds with which she intend to carry out her proposed investments in your country is invested in the oil rich Delta region of West Africa; she needs your assistance to transfer the invested funds to your country in a convenient bank account that will be provided by you before she can put the funds into use in your country. Should you be interested to help, feel free to contact me with your private telephone numbers for discussion of this transaction. Thank you in anticipation of your cooperation. Sincerely, Rev. (Barr) Dave Igebe Pro-Director, Rwanda Rehabilitation Project (www.rwandaproject.org)

Questions on Storage Allocation with Snap Manager for Exchange
by Hadrian Baron 20 Jul '06

20 Jul '06

We are running Snap Manager for Exchange 3.1 R1 with an Exchange 2000 cluster. LUNs are sitting on a 940C with DOT 7.1. Lately we have been having issues with our server getting very close to filling up their log drive. We have the Snap Manager directory also sitting on the Exchange log drive. To alleviate this issue temporarily I created a seperate LUN and pointed SME to store its own log files there instead. Until we can upgrade to SME 4.x (no more SME log directory), I have two questions: 1. Is this a best practice to store the SME log files on a different drive/LUN than the Exchange log lun? 2. Would it harm or significantly slow down the SME backup process to store the SME log LUN on an R200 instead of our 940? How does everyone else have this set up? Thanks for your input, Hadrian Baron Network Engineer VEGAS.com

RE: Suggestions regarding migration from 740 to 270
by Fox, Adam 20 Jul '06

That's pretty much the accepted procedure using ndmpcopy. Of course, if your plan is only to do one pass of the active filesystem, you will need to cut off users during that transfer so that changes don't get lost. Or you could do multiple levels of ndmpcopy and cut off users at the last one. -- Adam Fox adamfox(a)netapp.com -----Original Message----- From: Michael Homa [mailto:mhoma@uic.edu] Sent: Wednesday, July 19, 2006 8:30 PM To: Fox, Adam Cc: toasters(a)mathworks.com; Blair, Bill Subject: RE: Suggestions regarding migration from 740 to 270 > It is possible to preserve snapshots and migrate data, but it's > tedious at best and unpractical at worst, it just depends on your > data. > > You can use ndmpcopy or qtree SnapMirror (I prefer QSM if you have it). > But basically > you start with the oldest snapshot you want to keep.

RE: directory efficiency
by Glenn Dekhayser 20 Jul '06

There used to be a Netapp tech report (I can't find it anymore) that gave some specifics on this very question; it was about large directories on Netapp versus other technologies; perhaps the paper has obsolete information.

I would think keeping it less than 100,000 wouuld suffice for WAFL, but at some point the client will take an inordinate amount of time to enumerate all of the entries.

But if you are accessing one file whose name you know, then WAFL will access it very quickly, even if the directory has many thousands of entries. I am pretty sure that WAFL avoids sequential directory scans by using hashing and/or search trees. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

RE: Suggestions regarding migration from 740 to 270
by Fox, Adam 20 Jul '06

It is possible to preserve snapshots and migrate data, but it's tedious at best and unpractical at worst, it just depends on your data. You can use ndmpcopy or qtree SnapMirror (I prefer QSM if you have it). But basically you start with the oldest snapshot you want to keep. Migrate that snapshot for each qtree you want to migrate (or I suppose you can just do the volume if you are doing ndmpcopy). Then take a local snapshot on the destination flex vol (probably with the same name). Repeat this process with each snapshot you want to preserve. Basically, you are building them from the ground up. It works, but like I said, it's tedious for most and impossible for some. Another alternative for those who don't want to go through this process is to just copy the active filesystem over using anything you want, then keep the older disks around until they would have been deleted anyway. Not sure how that would work with your manual snapshots, but some sites with time-based snapshots have found that to be more practical, even if a bit inconvient, for a few weeks/months. Hope this helps. -- Adam Fox adamfox(a)netapp.com -----Original Message----- From: Michael Homa [mailto:mhoma@uic.edu] Sent: Monday, June 05, 2006 3:51 PM To: toasters(a)mathworks.com Subject: Suggestions regarding migration from 740 to 270 Hi: Recently, we elected to replace our primary 740 (we have two) with a 270.
