Moveing Exchange databases and logs

On my enterprise exchange server the MDBDATA folder that stores the log files and the databases is at 19 gig.  I have have a NStore fiber channel array that is 2gbs on a 2gps Sanblox Qlogic fiber switch that supports the 2bps fiber.  I believe the Sanblox 5200 has a 10gig backplane.  

Eventhough I think this is fairly fast I was wondering if it is wise to move the database and logs to the NAS storage box.  I have a fiber card in the server that access the the NAS box.  Here is the link to the NAS unit.  I'm providing this because of the performance of the system in dealing with remote databases.

Anyways, is it wise to move the databases to a NAS or just add more disk space to the server?

Thanks for your help.

As long as the storage is seen as a disk drive to the server then you are fine to move it to the storage server although I am sure the server will see the storage as a drive.
The data can be moved to a different drive already attached to the server if needs be ... follow Mark Fugatt's advise here http://www.msexchange.org/tutorials/MF001.html although this is for 2000 it is the same process for 2003. you have not specified which version you have.

Is it wise? well depends on your recovery strategy and how quick you can get things back from backup, and wether or not you want the space on the storage server used for this function... I would do it, as storage servers have noramlly a quicker access time than normal raid disks in raid 5 configs.

hope this helps

I haven't done the change yet.  I will try it out this next weekend.  I've done this before but I had heard that move the database to a NAS unit may cause corruption.  However, I think my network is fast enough to support this.

Thanks,

When I said, I've done this I move the databases to another drive on the same server.  This time I'm going to move it to my NStore box.

Make sure you have a full backup before doing this just to be sure.
