The best practice in setting the RAID Configuration for Exchange Server 2007
Hi All,
Im currently in the process of rebuilding my Dell 2950-III server which has got these specs:
1x Quadcore Xeon 5420 @ 2.33 GHz 5x 400 GB SAS 10k rpm HDD Dell PERC 6/I RAID Controllers 16 GB RAM
RAID connector 0: 4 HDD RAID connector 1: 1 HDD
While inside the Dell RAID configuration utility apps, I saw the following configuration:
Stripe Element Size: 64k Read Policy: No Read Ahead* Write Policy: Write Back Disk Cache Policy: Disabled
From: http://g4u0420c.houston.hp.com/en/B7961-90025/ch12s02.html You cannot set the read policy on a RAID-5 data plex. RAID-5 plexes have their own read policy (RAID).
As Im about to use this server as the RAID-5 for Exchange Server 2007, is there anything that I could tune for the best performance?
Thanks,
AWT

We can get the recommended configuration suggestions by putting RAID 5 into Storage Requirements Calculator
I assume that its a small/middle size environment, so IOPS shouldnt be the issue. Otherwise, please consider using RAID 10, the following resources will help

How's the deployment? Any update?

it went fine, it seems that having a faster 10k rpm SAS drive could be a big impact in terms of memory usage (now lower). I guess it is because the email queue scanned and processed faster :-) Cheers./* Windows Infrastructure Support Engineer */
