Re: Filesystem for Archive logs in RAC

I'd agree with the FRA option, but if you have a small number of nodes, and you want the comfort of having your archive logs outwith ASM, you can potentially implement cross instance archiving to local storage on all nodes.
Essentially all nodes then have copies of all archived redo, and you neatly swerve around the problem Tim mentions of an archive log being unavailable should a particular node crash. In some ways you could argue this is better than having your eggs all in the one basket of 1 storage array.
