How can I make a full use of those 8 hard disk to have maximum hard disk space with redundancy?<br><br>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:<br>
<br>disk1 to disk2 <<<<<<<<<<<-- OS/software- RAID 1 + 0<br>Disk3 to disk 8 = RAID5<<<---- for voicemailbox.<br><br>But heck , it doesn't give an option to manually define. <br>
<br>other question always bugs me<br><br>Question#2:<br>---------------<br><br>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?<br>
Assuming unity 4x server has RAID configured - disk1-2 = os, disk3-4 = D drive, disk5-8 = exchange server.<br><br>Would CCM or UCxn DVD modify the RAID config according to what they need?<br><br><br>
