Hi, We would like to upgrade 2 of our filers to DataOntap 7.3.0P3 and we would like to know the time it is going to take for the inode conversion. Details: F840.....6.4.4P8 (diskspace 5.4TB) FAS960.....6.4.4P8 (diskspace 20.2 TB) Also some of the volumes are around 90 - 95%. I appreciated your input....

Good Day, I am writing you in respect of the GLOBAL relief agency Medecins Sans Frontieres Charity Organization reimbursement donors campaign worldwide. The Organization is refunding back to donors their money out of the surplus 83 million euros they want to return to all donors who refused the Charity's offer to redirect their donations to lower profile cases like Sudan or the Democratic Republic of Congo. Please check the web link below for more information: http://news.bbc.co.uk/2/hi/asia-pacific/4535565.stm I am soliciting for your kind co-operation, to act as one of those that have donated funds to this charity organization and would want his/her fund return back to him/her so that part of this surplus 83 million euros will be reimbursed to you for us to share. Moreover, the amount to apply for should be 6.5million euro. This is the amount I have updated the information in my department and everything is set to be done legally without any fear or doubt. Upon your acceptance, reply me through my personal mailbox :(philippe.gil@3xl.net) for details. And I will send you backing documents issued to those who donated to victims of tsunami through MSF to enable the Organization reimbursed you with (6.5million euro) part of these surplus funds they are returning. In regards to your agreement with me, I will inform you on your percentage for your assistance. Best Regards, Philippe Gilot Account Officer, Medicines Sans Frontieres Charity Home.

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?

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

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.

Let's assume that my volume, call it, vol2, has two filesystems: A and .snapshot. Under .snapshot, I have three snapshots: oldest, old, latest. I start out by ndmpcopy the oldest: ndmpcopy -da -sa source:/vol/vol2/.snapshot/oldest/A destination/vol/vol2 Then, I take a snapshot on the destination: snap create oldest Next, I do old: ndmpcopy -da -sa source:/vol/vol2/.snapshot/old/A destination:/vol/vol2 snap create old Finally, latest: ndmpcopy -da -sa source:/vol/vol2/.snapshot/latest/A destination:/vol/vol2 snap create latest. Then, I proceed to do a level 0 ndmpcopy of vol2 ndmpcopy -da -sa source:/vol/vol2 destination:/vol/vol2 Michael Homa Operating Systems Support and Database Group Academic Computing and Communication Center University of Illinois at Chicago email: mhoma(a)uic.edu > you are > building them from the ground up.

RE: directory efficiency
by Glenn Dekhayser 20 Jul '06

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. Glenn (the other one) -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Stephen C. Losen Sent: Wednesday, July 19, 2006 4:54 PM To: Glenn Walker Cc: Page, Jeremy; David Lee; toasters(a)mathworks.com Subject: Re: directory efficiency > These considerations still matter, but the number of files in a directory have to be pretty large for performance considerations to come into play.

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. Perhaps something more along the lines of 10,000 entries would be a good place to start? > Directories with thousands of entries are always slow if you need to scan the entire directory to list its contents or look for file names that match a pattern. 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
