Thanks for the CIFS info, I remembered someone mentioning this, but had a hard time finding any documentation on this.
You are making out the iSCSI thing out to be a lot worse than it really is.
You can mount snapshots as writeable volumes to the server and copy of files out of them into the main LUN. This is particularly easy with SnapDrive, and takes all of 5 minutes to have a snapshot mounted. You can then copy the files off. This makes recovery of individual mailboxes easy, without requiring a lot of space.
Additionally to backup, you mount the snapshot of the LUN to a server and read the files off using a host agent rather than just backing up the LUN files, this allows quicker recovery from tape for individual nsf files.
All of this is easy to accomplish with SnapDrive.
I like the CIFS method as recovery from snapshots is easy, but if you have a lot of traffic this can be an issue (CIFS isn't a particularly fast protocol compared to iSCSI).
Anyway just wanted to clear that up a little.
Thanks

I used to work at a place where we deployed Domino over CIFS.
The application worked extremely well and setting this up is almost as easy as using DAS storage.
As far as I remember NetApp recommend you use the AUTOEXNT.EXE (resource kit tool) to run a batch file which maps your drive/s when the server starts and you must also run domino as a service rather than an application (a choice during install). Domino is happy to access data files on mapped drives.
Don't forget if you decide to use iSCSI you have to have an area big enough on your filer to restore the entire LUN just to retrieve one email (potentially). Also, your user would have to wait for the entire LUN to be restored from tape if you don't have a snapshot available. Flexclone may help with this but I'm not sure as I've not used it.
The beauty of this is that restore can be done easily and quickly from regular snapshots as .NSF files are pretty robust.
As far as clustering goes I would recommend using Domino application clustering over windows clustering especially if you have more than one site with decent bandwidth between them. It will give you a full DR solution and means you don't have to buy a snapmirror license if your using the filer exclusively for Domino as domino can handle replication pretty efficiently.
I also recommend that if you have roaming profiles hosted on a filer you keep your users personal notes data files (there are about 4 or 5 main ones such as address book) somewhere in the profile. Just means you can recover these just as easily.
Hope that helps.

Andrew,
I worked with a customer here to deploy NetApp storage with their existing Notes on Windows installation.
The Notes databases are effectively files rather than open databases, so SnapDrive initiated snapshots are sufficient for recovery without having to quiesce them.
The implementation we used was a LUN mapped to the Windows host with SnapDrive. We then created a Windows Scheduled Task to take regular snapshots using SnapDrive. To recover an individual mailbox, you just mount the snapshot of the LUN and copy that users mailbox file out and back into the main LUN, to recover all of Notes to a point in time, you just shut down Notes and do a LUN SnapRestore then remount the LUN and restart Notes.
There used to be some TR's for Lotus Domino, but I can't seem to find them anymore.

Andrew,
I could be wrong, but without application-specific support to quiesce the Notes databases (which is what SME/SMSQL/SMO do), then you won't be able to get guaranteed consistent snapshots. In addition, even if you do get good snapshots, you would still need some level of application-specific software (like SMBR) that understands the Notes database format and has the ability to reach into a snapshot and retrieve specific pieces of information.
Without these application-specific pieces, you are left with the ability to take "ordinary" snapshots (I would assume of a LUN, since Notes probably doesn't support mounting databases over CIFS or NFS) and then using SnapRestore to restore those snapshots as needed. I'm not intimately familiar with Lotus Notes, but if you could restore the database from snapshot to an alternate location you could then use Notes-specific software to retrieve specific items from there.

Has anyone installed, implemented, deployed Lotus Notes with a NetApp filer? I know there "SnapManager for Lotus Notes" doesn't exist so how can I do this with the same functionality and SME, and SMBR for that matter. I would appreciate any suggestions.
Thanks
