Suitable number of hard disk

By noorazman ·
Dear all,
I will buy a compaq server ml330. It will run win2003 and oracle 9i. I wish to do RAID and I will buy smart array model 641. It is capable of RAID 0, 0+1 & 5. Let say I have 3 unit 36.4gb SCSI HDD. What kind of RAID should I do ?
I would prefer an on-line standby, please advice.

RAID 5 would be your best option, but for an online standy you would need an additional drive. You can do RAID 1 with a standy, but if you have a failure, I believe you will have to power down to insert the standy drive. With RAID 5 you should be able to "Hot-Swap" without powering down.
