Configuration of the SAN

Hi,

We are trying to do a good configuration of our SAN. Let's see that exemple.

EMC, with disk of 146G.
- one LUN of RAID-5 for data (4+1 disks = 534G)

• one LUN of RAID-5 for index (4+1 disks = 534G)

Here is my question, about redo logs
- one LUN of RAID-1 for redo group 1 (2 disks mirroired = 146G)

• one LUN of RAID-1 for redo group 2 (2 disks mirroired = 146G)
• one LUN of RAID-1 for my archived log files (2 disks mirroired = 146G)

I will have a filesystem of 146G to store my redo group of 2G .... what a waste. Same thing for my redo group 2 and my archived log files ...

What is your LUN configuration regardinf redo log groups and archived log files ?

Thank you
