We have a server with 8 SAS internal disks. The OS is going to be RHEL 5 x86_64

We plan to mirror disk 1 and 2 using software RAID -- OS and Oracle software will be kept on this

Remaining 6 disks will be used for ASM.

Need your expert opinion on how to use the disks efficiently to maximize the available space without loosing ASM performance benefits much.

Our main worry is that if we spare 2 disks for storing online REDO logs (different ASM diskgroup with fine striping) then it will be a loss of space as well as we will have only 4 disks to store remaining oracle database files hence loosing performance a bit.

Please suggest how should we layout the various files under ASM.
