[cisco-voip] Unity connection 7x RAID controller best practice

these are appliances expecting a certain type of hard disks in a certain config. I'm pretty sure in the past and now, things have pretty much always been 2 sets of mirrored disks. 

i don't usually say this, but i'd just leave things better off alone. the installation process will overwrite whatever you have anyways. 

would raid 5 be better? yes. raid 6 would be even better! but those controllers cost more and you need more bays. with the newer models you have 8 bays, so two raid 6 arrays would be neat. or just one raid 6 array would be fine. 

you could always file a PERS. ;)

I can't find any document which gives me a clear idea of bumping up the disk space in 7845-H2 server. 

I am thinking to order a 7845/h2 hardware with 8 x 156 Hard disks in it. 

Question#1: 
---------------- 
How can I make a full use of those 8 hard disk to have maximum hard disk space with redundancy? 

If Unity cxn had an option to manually define partion and had option to define message location in a certain partion, I would do this: 

disk1 to disk2 <<<<<<<<<<<-- OS/software- RAID 1 + 0 
Disk3 to disk 8 = RAID5<<<---- for voicemailbox. 

But heck , it doesn't give an option to manually define. 

other question always bugs me 

Question#2: 
--------------- 

What happens to the disk array of unity 4 server, when we pop-in Unity connection or call manager DVD and try installing CCM5/6 or UCxn 2/6/7x on unity 4 server? 
Assuming unity 4x server has RAID configured - disk1-2 = os, disk3-4 = D drive, disk5-8 = exchange server. 

Would CCM or UCxn DVD modify the RAID config according to what they need?
