Re: Do you still ned RAID 5 if you follow OFA?

You have to understand that RAID can serve two purposes...speed and protection from Drive failure. RAID5 is to protect against Drive Failure (God knows you don't run RAID 5 for speed). If you are operating without a RAID solution, and if one of your drives crash, you would need to replace the drive and restore the lost datafile(s) and recover your database. If you have a RAID solution in place, and experience a Disk crash, your database will still be up and you can "simply" replace the damaged disk (Hot-plugable in most cases).

I have yet to see a company that doesn't use some sort of RAID solution on thier production machines (Doesn't mean it doesn't exist).
