Thus, not only does the hardware platform need to support such an approach but the individual SAP Technology Stack layers and components that sit atop the hardware stack must support dynamic reallocation as well. These types of solutions are labeled "hardware partitioning" and are typically predicated on less than commodity hardware platforms. • Software partitioning is becoming more popular, too, as companies like Microsoft and VMware (recently swallowed up by EMC) promote virtualization software that allows a single physical server and its resources to be chopped up virtually into multiple servers, each capable of hosting applications in a "guest" OS instance.
