San & single point of failure
Date: Mon, 17 Nov 2008 12:50:45 -0800
I have just been given a new server to put a database on. It is a SAN server, but the apparent layout of drives to me is:
This means that I have just put control_file1, 2, and 3 all in the same place - on /big. I thought that the whole point of multiple control files was to avoid single points of failure, such as a single location.
I am told that SAN layout is to handle mirroring, striping, & hot spots behind the scene and I don't need to worry. If this is true, why do I need duplicates of the control file?
Something smells fishy to me. Does anyone else have an opinion?
