Hi Davide, Dynamic Reconfiguration (DR) is a hardware+software feature of midrange and high-end SPARC systems and so it is available on SPARC only.
With DR you can add or remove to a domain a physical board (4 CPUs with memory) on E3800-E25Ks or even a single CPU (with memory) on a M-series system. Dynamic Recource Pools (DRP) is a Solaris 10 and OpenSolaris feature that is available on any platform Solaris runs on. With DRP you can partition a domain in pools of "Solaris processors" (that can be cores or threads/strains on multi-core/multi-threaded processors) and have the number of processors change to match a certain goal (usually maintain CPU utilization < certain percentage). You can use pools as a resource constrain for Solaris Containers/Zones or for a Solaris Project. With Zones you can use the Fair Share Scheduler (FSS) to have an even more flexible CPU allocation.
