Giving over 25% of the IOPS capacity to OS+ORACLE_HOME? Is there a lot of
UTL_FILE , securefiles or other such demand for structured data?
Also, how are these 8 disks connected to the system (specifically what I/O card
and what is the nature of the PCIe slot they plug into) ?

Subject: ASM+internal disks
Hi,
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.
