raidsize recommendations
by Tavis Gustafson 21 Oct '04

21 Oct '04

I usually setup my filers with raidsize=7 having no more than 7 disks per volume. However, I would like create a raidsize=13 volume. The only risk i can glean from NOW is that rebuild time will increase and thus increase the chances of a second drive failure (during rebuild). Has anyone had any real world issues with using volumes of raidsize > 10 thanks, -Tavis

Hi Alan and Skip, This is just an "FYI" to eliminate any confusion. There has never been a version of SnapManager which supported the use of Exchange 5.5 on VLD. The first version of SnapManager for Exchange to support the use of Exchange 5.5 databases on NetApp LUNs is the most recent release, version 3.1. NetAppDrive is included with the SnapManager for Exchange 5.5 product. Its purpose is to maintain the CIFS drive letter mappings to the filer which Exchange uses as well as monitor the Exchange services. SnapDrive it different. It is a separate product and it is used for iSCSI and FCP LUN provisioning and management. Hope this helps.

Also, make sure that you have all the SP and hotfixes installed as per the NetApp SnapDrive/SnapManager Documentation. One other issue is the licensing of the newer versions of SnapDrive & SnapManager. You'll have to consult your agreement to determine if you can upgrade. Also, these products are now licensed either on a per filer or per host basis.

Tavis, Once we get raid groups above 10 or so then we start using the double disk parity. That way you have to lose 3 disks in a raid group before you have data loss. I think this was available in 6.5 and above. - jay -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Tavis Gustafson Sent: Thursday, October 21, 2004 2:29 PM To: toasters(a)mathworks.com Subject: raidsize recommendations I usually setup my filers with raidsize=7 having no more than 7 disks per volume.

One of my filers (F740 running DataONTAP 6.3.3P3D1) has one RAID group with 12 data disks, one parity, one spare, currently over 90% full. We had a data disk fail just a couple of days ago. The message file says reconstruction took 1:13:35.71. This is an older system that has had several disk failures, but never on the same day, let alone within an hour and a quarter. :-) ObWarning: Your mileage may vary. owner-toasters(a)mathworks.com wrote: > > I usually setup my filers with raidsize=7 having no more than 7 disks > per volume.

RE: replicating exchagne databse
by SKIP HOFMANN 21 Oct '04

We use nuview or another name for it is VFM. I setup a replication policy to replicate the DB and logs from the snapshot dir (most recent) and replicate this to the R200. If single mailbox restore can open up the DB then the DB has got to be good, so if I can replicate the DB and logs back to the FAS 250 point snap manager for exchange to the replicated DB then I'm thinking I should be able to mount the DB and get outlook access to it.

Hi Skip, Are you using SnapManager for Exchange? If so, then there is a new KB article on this topic which may be of interest. KB article 3990 is titled "Using SnapVault to Archive SnapManager for Exchange Backups Sets" and can be found on the NOW site. I think the paper details the solution that you are looking for. http://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb3990 <http://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb3990> Regards, Paul Benn NetApp ________________________________ From: SKIP HOFMANN [mailto:SKIP.HOFMANN@ttisg.com] Sent: Thursday, October 21, 2004 9:39 AM To: toasters(a)mathworks.com Subject: replicating exchagne databse Hi all We have our exchange DB on a FAS 250. We take 3 snapshots of the logs and DB everyday. I want to know if I can replicate the most recent snapshot of the DB and logs to my R200, and if a disaster were to hit could I copy this DB back to the FAS 250 and mount it? We use single mailbox recover version 2.11 to restore emails and inboxes. If point this product to the replicated exchange DB on the R200 It does work the product does read the DB and I can recover inboxes and emails. So I guess my question is a snapshot of a DB once moved off of a fAS250 to an R200 can it be remounted by snap manger for exchange once the DB is copied back to the FAS?
