correct device type to use for exchange database... ?

dcox · by **dcox** » Tue Nov 18, 2008 8:03 am

I'm not sure all the possibilites, but it appears there are at least two.

What would be the best type of device to create to hold the exchange data if it would be stored on an iSCSI target?

"Image File device" or "Snapshot, CDP & De-Duplication device" or something else?

I'm not familar yet with the snapshot solution, so I'm not sure if that would apply for a DB or if it was more designed for files.

Thanks,
Duane Cox

If you don't want to protect your database content with the CDP and if you don't want to take any snapshots - obviously use flat image file as it's faster (CDP thing needs some extra CPU cycles for internal housekeeping).

is it possible to use CDP with exchange? Meaning, would I be able to resotre an individual email and not the entire DB? I plan on using tape to do off site storage and long term archiving...

I wasn't sure CDP would give me the benefit of selecting individual emails as a restore option, rather I invisioned it restoring the entire DB...

Please clarify.

Any application which is VSS aware will be usable with CDP.

so do I use the iSCSI CDP over top of VSS (in addition to), or aside from?
Sorry, I'm new at this and trying to learn as much as possible as quickly as possible.

We use VSS to signat to the application it should suspend writers. So if application is VSS-aware (does process VSS callback to hold the writes) we'll create consistant image. If not (application is old and broken) - we'll create inconsistant snapshot (or CDP increment).

In that case, am I to load the "StarWindVSS.x64.exe" VSS Helper on the iSCSI Target Server?

On initiator side.

any users out there (on the forum) that's using exchange with this kind of setup?

What's the feedback?

No idea about the forum but we do have customers with such a configuration.
