True High Availability Architecture

Hello,

Is it truly possible to design a High Availability Business Objects architecture?

A clustered CMS, network FRS will reduce failure points. However if the machine that hosts IFRS/OFRS goes down, i would have to manually create/activate IFRS/OFRS in another cluster machine as we cannot have more than one FRS service running at a given time in the environment.

Is there a way to automate so that fail-over is automatic? Your feedback/advice is much appreciated.

Thanks
