Thanks for the info and feedback..... we are a small shop and currently
support 20 -25 users, but we want to build a box that will allow for
expansion up to 50 users before needing to replace hardware again.

Raid 5 should not be used for any kind of logs. Logs by nature are read
and write intensive. Raid 5 will slow down on heavy write.
If you can only have 4 drives, use 2 drives Raid one for OS, Page file
and logs. Use 2 drives Raid 1 for database.
If you can have 6 drives, use 2 drives raid 1 for OS and page file, 2
drives raid 1 for transaction log and 2 drives Raid 1 for database.
It kind of depends on the work load too.
How many users and what kind of usage?

I am in the process of identifying requirements for a new Exchange 2000
box and would like some clarification....
In an effort to keep costs manageable we were considering serial ATA
drives in some sort of RAID configuration.
If we have a separate drive for the OS should it also be a serial ATA
drive or can it be a standard IDE drive on one of the motherboard
controllers? If not recommended, I guess it should also be a serial ATA
drive on its own controller?
We were thinking of a RAID 5 configuration for the storing of the
Exchange database and logs. This would be a separate serial ATA
controller....
Not being a hardware techie... I'm not sure if I'm on the right path
regarding the hardware configuration....
Any advice from those who are?
Thanks

If money is a concern, here is my .02:
All drives Dynamic (unless mirroring the SCSI via hardware raid) and all
NTFS.
2 EIDE HD.
Partition 1 Partition 2
Partition 3
Boot and OS (Mirrored) Page File (One on each drive)
Exchange Tran log (Mirrored)
2 SCSI
One partition. Mirrored. Exchange DB.
The reason for have 2 page files, each on a separate partition on
separate drives, is it is not recommended to mirror the page file, and
having 2 will keep you from having a blue screen in the event of a drive
failure.
