Re: databases and RAID ...

Good Morning Mallah,
I've heard bad things from a friend that worked at IBM about using RAID and
databases. He said there could be a definite performance hit with a
hardware raid controller doing RAID5, so i can only imagine that software
raid would be worse :(. Mirroring should be as bad, but i would definitly
look into a hardware raid controller if you could.
hope thishelps
corey
