We used four partitions across 3 disk on a 2650. 

1. OS (RAID1)
2. Imail (RAID1)
3. Users POP3 (RAID1)
4. Imail spool - stripped

At least that's how I think we did it!!! :)

Subject: [IMail Forum] Imail Drive/Partitions



I have a situation with available hard drives and Imail partitioning
that I'm unsure of. (I am VERY familiar with the optimum setup, so
please keep reading).

I have 3x 15k RPM 18G hot swap drives on 64M RAID card.  This Dell 2650
will hold 2 more but NO money in budget for any more.  This machine will
be used as a gateway as Store and Forward only to Exchange so there will
be no user mailboxes to speak of.  It will be doing A/V and Anti-Spam
and handle about 150-200k messages per day.

Now, I can't figure out the best setup for the drives.  I don't want to
make them all 3 a RAID 5 set because I don't want the spool on RAID 5.
It would be a waste to use each drive independently and lose any
redundancy.  So, the only setup I see is RAID 0 and a single drive.
Should I put the OS/Page File/Programs on RAID 0 and the spool on the
single drive?  Or just put everything on the RAID 0 pair since storage
space won't be that much of an issue?  Or put the OS/Paging on single
drive and spool/programs on the RAID 0? (Of course all in separate
partitions).  I just can't figure out the best scenario.

Any input greatly appreciated.

Thanks
