Volume heavily fragmented

Server: SBS 2003 w/ Exchange using Diskeeper 10 Enterprise Server

The report shows warning that the volume on C drive has been degraded - heavily fragmented. I have been trying to remove all unnecessary software. I will work on volume shadow copy to reduce the size but am running out of options. The exchange has total of 21 GB..

See below from diskeeper report - any feedback and thoughts would be appreciated especially I'm bit confused why it shows: fragmentation percentage = volume fragmentation: 41%; data fragmentation: 60%

Is that bad ? How can I improve this situation? Thanks!

The obvious answer is that Diskeeper will reduce your fragmentation, but I don't believe that the answer is that simple.  Be sure to run a boot-time defrag on it, first.

You must actually have another question in mind.  What is it?

Yes I have been running Diskeeper constantly and still get the same result..

I will be rebooting the server tomorrow evening when the main office closes to defrag the paging file..

I'm seeking for more info on how to improve the situation other than diskeeper running defrag and boot time defrag as well.. or am I doing the right thing?
If you run defrag then analyze immediately after, is the drive almost as fragmented as when you started?

Actually very beginning using Diskeeper a year ago - stated healthy and avg frag per file was 1.0 and now it's 1.12
If your exchange database is big your not leaving much room to work within (free space) . Your rate of fragmentation will increase when moving within such a small free space. If you could add disk space, you'd be better off. I would not go below 25% free space.

Exchange does well when it has lots of free space for the database to move around in.

Hmm..I've been wondering if it is possible to redirect the Exchange data to different hard drive instead of C drive ?
Lee W, MVPTechnology and Business Process AdvisorCommented:
Why is everything on the C: drive?  This is inefficient and, in my opinion, potentially dangerous.  You have a HUGE C: drive - if the server was properly managed.  One reason you're fragmenting so much is likely to be exchange - the Exchange information store is constantly growing and as a result, using more and more space.  In the mean time, other things on the C: are also using more and more space - like the MSDE SQL Databases, Logs, and Windows Updates.

I would strongly encourage you to reconfigure your server and put ONLY the operating system and application executables on C:, putting the data on other drives.

The reason you're probably having difficulty defragmenting is that the Exchange database is so fragmented and using 1/2 of the used space and is otherwise always in use.  Further, this fragmentation is probably affecting your overall exchange performance.

For help cleaning up your C: drive, I would suggest you review my web page on Boot Drive Sizes - www.lwcomputing.com/tips/static/bootdrivesize.asp

Yes, the Exchange Database SHOULD be redirected to a different drive - see:

(Sorry - I typed that previous comment out about 25 minutes ago and the post didn't catch for some reason... came back to the tab and it was still there).

I agree - am picking up the slack and mess from former IT manager and got bad feeling about this..

Thanks for your 2 cents..
SBS defaults everything to C. The person who installed it maybe left all of the defaults.

Definitely add additional RAID'd space, and relocate the Exchange databases to it. If this is your only server, then you may also need to move the shared files to the new space as well....

kgspitfireAuthor Commented:
*nod* yes that's true.. this main server as primary domain controller has 2 drives (C and E)

C drive: exchange and sql

E drive: shared folders

ClientApps and others on 2nd server (backup domain controller) but this server is dedicated for several databases - don't think it's good idea to move Exchange database there..

I'm figuring out how to install additional RAID on primary domain controller - would need 2 hard drive to mirror to each other correct?

correct. Typically to install additional RAID, you get a good raid card and a direct attached storage unit, unless you have more room in the server, in which case I hope it's just easy hot swap adding....

However, consider something more scaleable than RAID1. Consider a RAID 5 or 10 (more cost, but best) setup with more drives.
You get more performance (speed) and much more space and potenetial for growth. Hardware is cheap, labor and time are not.
An external RAID setup would allow you to move it later to another server...
