Re: Fwd: RE: RAID or NOT to RAID?

OOOOOOOOOOOOOOOOh Paaaaaaaaaaauuuuuuul!

Can you give a quick explication of how many drives/mount-points are advised, in terms of recovery issues, for the OS (NT/Win2k), Oracle software, database files, etc.?

(is there something about this in Sean O'Neill's NT standards document?)

thanks,
ep

ps, glad you enjoyed the midwest, I have a friend in Omaha.
