Exchange Server problem

[Firefly86]

Hi guys,

Need some advice for my exchange server.

THe server is running Exchange Server 2003 on Windows Server 2003 Standard Sp2.

It supports around 100 mailboxes at the moment.

Its a DL 360 G4P, 4GB RAM with 2 x 250GB SATA drives in a Raid 1 configuration.

The problem is that for the past few months, there has been a very high amount of disk usage, to be more specific, disk utilization is at 100% for the better part of the day!

I suppose this is not normal, and its been recommended I upgrade my disk subsystem.

Was thinking of setting up larger hard disks in Raid 4, then I realised my exchange server only has 2 slots for hard drives.

I know its never recommended to use Raid 0 on an exchange server, what else can I do? I do however use Neverfail for Exchange so wondered wether maybe then Raid 0 was acceptable? Or still stupid

Current setup of exchange is as follows :

C Partition (30GB) : OS files, exchange installation and page file
D Partition ( 220GB) : Exchange .edb, .stm and .log files from various storage groups

This was how the setup was when I originally arrived at my current workplace

Any suggestions on how to improve performance?

not sure if this is exactly what you mean but its the store.exe process which is making the most disk requests. How can i collect data on this?

Ive monitored using performance but that dusnt really tell me whats causing *** activity
