|Description||string||A Partition is an instance of a UnitaryComputerSystem (with its own OperatingSystem and Devices dedicated to the Partition) that is supported by underlying hardware and software. A Partition is not a virtualization of a Computer System, but the segmentation of the System's compute capabilities. Partitions can run independent copies of possibly different OperatingSystems and have dedicated Devices. The 'real', underlying System (perhaps a Cluster or another UnitaryComputerSystem) aggregates its Partitions. These semantics are described by the System Partition association.
