Hi sachin
In case you have a single SSA controller , I suppose you would be better off
putting all your disk in one raid , so you can stripe across five disks
instead of 3 or 2 as the case maybe.

Subject: How many SSA disks to configure in a RAID array ?
Hi
I am going to install 5 x 72 GB SSA disks (10K RPM) in RAID 0 configuration
in a 7133 box. I have a SSA controller with onboard 128 MB SDRAM & 32 MB
FastWrite cache. Do I configure 1st RAID 0 set with 3 disks in loop A and
2nd RAID 0 set with 2 disks in loop B or do I configure these 5 SSA disks in
single RAID 0 array on loop A ? I am not bothered redundancy / fault
tolerance.
Your expert comments please ....
Thanks & regards
