Rossaluss's questions

We've recently purchased 2 x Dell R710s and 2 x Dell MD3400 SAS storage devices with 12 2tb drives in each with 2 dual SAS connections from each server to 2 dual raid controllers on both MD3400s (I've attached a diagram to show the connection config).

It's my first foray into DAS and I'm trying to set it all up using guides and am struggling to accomplish what I'd like to do.

What I'm after is creating a virtual disk that contains all the disks on both the MD3400s (raid 5, creating a ~40tb drive), however I'm not sure if I'm able to pool the disks on the separate MD3400s to create this. I only seem to be able to find a way to create 2 individual virtual drives of ~20TB each on each individual MD3400.

Is what I'm trying to do possible? Or would we need to interconnect the MD3400s directly with SAS cables?

Any help would be greatly appreciated.

There's a user on our exchange who moved a subfolder of his inbox into a subfolder beneath that, and now an infinitely nested folder loop has been created (see screenshot).

This is prevalent on both Outlook 2007 and on OWA so it appears to be an issue server side, however I can't think what will have caused it let alone how to resolve the issue.

I've tried to create a copy of the folders and then move the copy back to a copy of the original folder structure, however when I've done this, the 2 looping folders are subsequently empty (When originally, they were not).

As this issue is also visible via OWA, the usual local OST fixes etc don't have any effect, and I'm drawing a blank on how this would be resolved and wondered if anyone has seen anything like this before and how to fix it?

The local client is Outlook (Office 2007) running on XPSP3 and the exchange server is running Windows Server 08 and Exchange 2007.

Thanks
