I'm planning to buy an IPS 4255 appliance, but I might need to increase the throughput in the future. Can I add IPS appliances parallel as and when I need higher throughput. Can those multiple appliances work as a single unit and not influence my existing design, when I need to upgrade the IPS throughput. Also, can this be done with any of the models in the 4200 family, interchangeably ?
Lot of questions, sorry if too much
